40153df63a imx: bootaux: get stack from elf file
To i.MX8, M core stack is pre-coded in source code, so need to get it
before kicking M core. The stack pointer is stored in the first word of
the first PT_LOAD section __isr_vector. So use a num to index the
section loading.

290ffe5788 imx8m: fix reading of DDR4 MR registers
I was trying to employ lpddr4_mr_read() to something similar to what
the imx8mm-cl-iot-gate board is doing for auto-detecting the RAM
type. However, the version in drivers/ddr/imx/imx8m/ddrphy_utils.c
differs from the private one used by that board in how it extracts the
byte value, and I was only getting zeroes. Adding a bit of debug
printf'ing gives me

 tmp = 0x00ffff00
 tmp = 0x00070700
 tmp = 0x00000000
 tmp = 0x00101000

and indeed I was expecting a (combined) value of 0xff070010 (0xff
being Manufacturer ID for Micron). I can't find any documentation that
says how the values are supposed to be read, but clearly the iot-gate
definition is the right one, both for its use case as well as my
imx8mp-based board.

So lift the private definition of lpddr4_mr_read() from the
imx8mm-cl-iot-gate board code to ddrphy_utils.c, and add a declaration
in the ddr.h header where e.g. get_trained_CDD() is already declared.

This has only been compile-tested for the imx8mm-cl-iot-gate
board (since I don't have the hardware), but since I've merely moved
its definition of lpddr4_mr_read(), I'd be surprised if it changed
anything for that board.

c329f9349b ARM: imx: imx31: Introduce and use UART_BASE_ADDR(n)
Introduce helper macro UART_BASE_ADDR(n), which returns Nth UART base
address. Convert all board configurations to this new macro. This is the
first step toward switching CONFIG_MXC_UART_BASE to Kconfig. This is a
clean up, no functional change.

The new macro contains compile-time test to verify N is in suitable
range. The test works such that it multiplies constant N by constant
double-negation of size of a non-empty structure, i.e. it multiplies
constant N by constant 1 in each successful compilation case.

The non-empty structure may contain C11 _Static_assert(), make use of
this and place the kernel variant of static assert in there, so that
it performs the compile-time check for N in the correct range. Note
that it is not possible to directly use static_assert in compound
statements, hence this convoluted construct.

Button is used by firmware to indicate (after reset, power up) that user

For bootloader or OS is this just user button which is worth to have it

Also button can be used as a wakeup source and pressing it for more time
can generate more chars that's why also adding wakeup-source and autorepeat

In all the ZynqMP boards dts files tx-buswidth is by default set to 1. Due
to this the framework only issues 1-1-1 write commands to the GQSPI driver.
But the GQSPI controller is capable of handling 1-4-4 write commands, so
updated the tx-buswidth to 4 in ZynqMP boards dts files. This would enable
the spi-nor framework to issue 1-4-4 write commands instead of 1-1-1. This
will increase the tx data transfer rate, as now the tx data will be
transferred on four lines instead on single line.

67bdaa0165 arm64: zynqmp: Fix split mode reset functionality
This patch fixes two issues in the set_r5_reset function.

1. When in split mode, the lpd_amba_rst bit should only be set when
both r5 cpu cores are in reset. Otherwise, if one r5 core is still
running, setting the lpd_amba_rst bit will cause an error for the
running core. The set_r5_reset function has been modified to check
if the other r5 core is still running before setting the lpd_amba_rst
bit.

2. The cpu_disable function was always assuming that the r5 cores
are in split mode when resetting either core 4 or 5. This is
incorrect for lockstep functionality. This patch adds a function
check_r5_mode to handle the cpu_disable function correctly for
the r5 cores by checking the mode and handling the reset appropriately.

So do it earlier in arch_very_early_init() instead of arch_cpu_init().

Movement is done in proper U-Boot, not in SPL. SPL may return to bootrom
and bootrom requires internal registers at (old) expected location.

outright 1V8 in case of 1V8 IO DHCOR without the Empirion DCDC converter.

The 2V9 mode in case of AV96 DHCOR variant is used to reduce unnecessarily
high input voltage to the Empirion DCDC converter, so move it into matching
DTSI to stop confusing users.

49bb245f1d armv8: psci: add ARMV8_PSCI_RELOCATE Kconfig option
There is an user-selectable SYS_HAS_ARMV8_SECURE_BASE, which has the
same meaning but is just for the ls1043ardb board. As no in-tree config
uses this, drop it and replace it with something more sophiticated:
ARMV8_PSCI_RELOCATE. This option will then enable the ARMV8_SECURE_BASE
option which is used as the base to relocate the PSCI code (or any code
in the secure region, but that is only PSCI). A SoC (or board) can now
opt-in into having such a secure region by enabling
SYS_HAS_ARMV8_SECURE_BASE. Enable it for the LS1043A SoC, where it was
possible to relocate the PSCI code before as well as on the LS1028A SoC
where there will be PSCI support soon.

Additionally, make ARMV8_PSCI and SEC_FIRMWARE_ARMV8_PSCI exclusive.

cb14cc8867 armv8: layerscape: get rid of smc_call()
There are two different implementations to do a secure monitor call:
smc_call() and arm_smccc_smc(). The former is defined in fwcall.c and
seems to be an ad-hoc implementation. The latter is imported from linux.

smc_call() is also only available if CONFIG_ARMV8_PSCI is not defined.
This makes it impossible to have both PSCI calls and PSCI implementation
in one u-boot build. The layerscape SoC code decide at runtime via
check_psci() if there is a PSCI support. Therefore, this is a
prerequisite patch to add PSCI implementation support for the layerscape
SoCs.

Note, for the TFA part, this is only compile time tested with
(ls1028ardb_tfa_defconfig).

However, according to Ran Wang in [1]:

 normal use case, I think it's fine."

So just disable this erratum by default for these processors.

The impedance of the QSPI PCB lines on the sama7g5ek is 50 Ohms.
Align the output impedance of the QSPI0 HSIOs by setting a medium drive
strength which corresponds to an impedance of 56 Ohms when VDD is in the
3.0V - 3.6V range. The high drive strength setting corresponds to an
output impedance of 42 Ohms on the QSPI0 HSIOs.
This is just a fine tunning. The memory that we have populated on sama7g5ek
works fine even with high drive strength, but it's better to adjust it and
use medium instead, in case some other flashes with higher frequencies are
tested.

a609353e82 arm: apple: Point stdout-path to framebuffer when keyboard present
Unless you have a spare Apple Silicon machine, getting access to
the serial port on Apple Silicon machines requires special
hardware. Given that most machines come with a built-in screen
the framebuffer is likely to be the most convenient output device
for most users. While U-Boot will output to both serial and
framebuffer, OSes might not. Therefore set stdout-path to point
at /chosen/framebuffer when a keyboard is connected to the machine.

This behaviour can be overridden by setting the "stdout" variable
in the U-Boot environment. I addition to that keep the serial
console as the default when running under the m1n1 hypervisor.
The m1n1 hypervisor virtualizes the serial port such that it
can be easily accessed from any other machine with a USB port.

LD 0 Marvell Internal Use line seems that was burned in factory with some

9e778c7ffc arm: mvebu: dts: uDPU: fix non-working networking
uDPU is a bit of a specific device in that it does not have any copper
ports nor any ethernet PHY-s but 2 SFP ports.

This is an issue since MVNETA requires a PHY phandle or a fixed-link to
be defined under its node.
Since U-boot has no SFP support this is reasonable in order to know how
to configure the MAC.

However this also means that networking does not work on uDPU at all
currently, and fails with:

uDPU>> dhcp
Could not get PHY for neta@30000: addr 0
phy_connect failed
Could not get PHY for neta@40000: addr 1
phy_connect failed

So, to provide working networking using only SFP-s let add the fixed-link
at 1G which is much more common than 2.5G SFP-s as well as disable the
TX_DISABLE pins like done on Armada 7040 and 8040 platforms.

Since uDPU is not using any of the GPIO-s on the SB controller for any
purpose other than GPIO, a call to the pinctrl must be made in order for
it to get probed and thus register the SB GPIO bank, otherwise SB GPIO-s
are not registered at all.

c8b00da695 arm: mvebu: a37xx: Add support for reading Security OTP values
It is not possible for the A53 core (on which U-Boot is running) to read it
directly. For this purpose Marvell defined mbox API for sending OTP
commands between CM3 and A53 cores.

Implement these Marvell fuse reading mbox commands via U-Boot fuse API.

Banks 0-43 are used for accessing Security OTP (44 rows with 67 bits via 44
banks and words 0-2).

Note that of the 67 bits, the 3 upper bits are: 1 lock bit and 2
auxiliary bits (meant for testing during the manufacture of the SOC, as
I understand it).

Also note that the lock bit and the auxiliary bits are not readable
via Marvell commands.

With CZ.NIC's commands the lock bit is readable.

Write support is not implemented yet.

a37b68820c arm: mvebu: Fix Espressobin build for configs where ENV is not in SPI
When storing the UBoot Environment in for example EXT4,
the U-Boot build is broken for several reasons:
1. armada-385-turris-omnia-u-boot.dtsi will not allow
   CONFIG_ENV_OFFSET and CONFIG_ENV_SIZE to be undefined
2. armada-37xx/board.c ft_board_setup function does not
   exist if CONFIG_ENV_IS_IN_SPI_FLASH is not defined

This commit changes these files so that selecting a
different location for the environment is possible.

730a402450 rockchip: rk3066: add clock driver for rk3066 soc
Add the clock driver for the rk3066 platform.

Derived from the rk3288 and rk3188 driver it
supports only a bare minimum to bring up the system
to reduce the TPL size for:
  SDRAM clock configuration.
  The boot devices NAND, EMMC, SDMMC, SPI.
  A UART for the debug messages (fixed) at 115200n8.
  A SARADC for the recovery button.
  A TIMER for the delays (fixed).

There's support for two possible frequencies,
the safe 600MHz which will work with default pmic settings and
will be set to get away from the 24MHz default and
the maximum of 1.416Ghz, which boards can set if they
were able to get pmic support for it.

After the clock tree is set during the TPL probe
there's no parent update support.

In OF_REAL mode the drivers ns16550.c and dw-apb-timer.c
obtain the (fixed) clk_get_rate from the clock driver
instead of platdata.

The rk3066 cru node has a number of assigned-clocks properties
that call the .set_rate() function. Add them to the list so that
they return a 0 instead of -ENOENT.

This is the only place where i.MX8M code does SMCCC call, remove it.
The output has little value as it prints some part of commit ID, and
worse, if there is no SMC handler installed, the code outright hangs
or crashes the system.

By removing this one instance of SMCCC call, U-Boot no longer depends
on SMC handlers and can boot without hanging in any case. If there is
a need to dump this commit ID, use CMD_SMC instead and do 'smc' call
from U-Boot shell or scripts instead of hard-coding SMCCC dependency
into architecture code. This particular code can be replaced by:
 => smc 0xc2000003 0 0 0 0 0 0

Card did not respond to voltage select! : -110

Fix this as follows:
- Re-name the signaling voltage rail regulator from vmmc to vqmmc.
- Fix the name of the GPIO property to gpios.
- Specify 4-bit bus width, no write-protect capability and no 1.8
  volt signaling voltage capability.

This commit also adjusts the code in setup_fec and follows

This commit also slows down the boot-process by about 150ms
as it now waits for the regulator-fixed-clock voltage that
drives the PHY to go up.

aa42894471 mx6: ddr: Wait before issuing the first MRS cmd
Wait 1ms before issuing the first MRS command to write DDR3 Mode
registers.

There is a requirement to wait a minimum time before issuing command to
the DDR3 device, according to the JEDEC standard this time is 500us
(after RESET_n is de-asserted until CKE becomes active) + tXPR (Reset
CKE Exit time, maximum value 360ns).

It seems that for some reason this is not enforced by the MMDC
controller.

Without this change we experienced random memory initialization failures
with about 2% boot failure rate on specific problematic boards, after
this change we were able to do more than 10.000 power-cycle without a
single failure.

09dbac8174 mx6: ddr: Restore ralat/walat in write level calibration
The current DDR write level calibration routine always overwrite
the ralat/walat fields to their maximum value, just save
the existing values at the beginning of the calibration routine
and restore it at the end.

In case the delay is estimated by the user to be more than one cycle the
walat should be configured according to that, this is not
automatically done.  From the i.MX6 RM:

   The user should read the results of the associated delay-line at
   MPWLDECTRL#[WL_DL_ABS_OFFSET#] and in case the user estimates that the
   reasonable delay may be above 1 cycle then the user should indicate it at
   MPWLDECTRL#[WL_CYC_DEL#]. Moreover the user should indicate it in
   MDMISC[WALAT] field. For example, if the result of the write leveling calibration
   is 100/256 parts of a cycle, but the user estimates that the delay is above 2 cycles
   then MPWLDECTRL#[WL_CYC_DEL#] should be configured to 2, so the total
   delay will be 2 and 100/256 parts of a cycle

Probably it would just possible to not overwrite the mdmisc register in
the first place, since this is not present in the write_level_calib() example
in NXP AN4467 nor in the i.MX6 RM (44.11.6.1 Hardware Write Leveling
Calibration).

This converts the following to Kconfig:
   CONFIG_CM_INIT
   CONFIG_CM_REMAP
   CONFIG_CM_SPD_DETECT
   CONFIG_CM_MULTIPLE_SSRAM
   CONFIG_CM_TCRAM

We make the first three of these options be always enabled, as that
matches usage.  We select the last two based on how they were defined in
armcoremodule.h.  This also allows us to remove some unused code in
board/armltd/integrator/lowlevel_init.S

4de720e98d Merge branch 'master' of https://source.denx.de/u-boot/custodians/u-boot-sunxi
A big part is the DM pinctrl driver, which allows us to get rid of quite
some custom pinmux code and make the whole port much more robust. Many
thanks to Samuel for that nice contribution! There are some more or less
cosmetic warnings about missing clocks right now, I will send the trivial
fixes for that later.
Another big chunk is the mkimage upgrade, which adds RISC-V and TOC0
(secure images) support. Both features are unused at the moment, but I
have an always-secure board that will use that once the DT lands in the
kernel.
On top of those big things we have some smaller fixes, improving the
I2C DM support, fixing some H6/H616 early clock setup and improving the
eMMC boot partition support.

The gitlab CI completed successfully, including the build test for all
161 sunxi boards. I also boot tested on a A64, A20, H3, H6, and F1C100
board. USB, SD card, eMMC, and Ethernet all work there (where applicable).

b9a2e18533 sunxi: eMMC: Improve automatic boot source detection
When the Allwinner BROM loads the SPL from an eMMC boot partition, it
sets the boot source byte to the same value as when booting from the
user data partition. This prevents us from determining the boot source
to load U-Boot proper from the proper partition for sure.

The generic SPL MMC code already looks at the enabled boot partition
number, to load U-Boot proper from the same partition, but this fails
if there is nothing bootable in this partition, as the BROM then
silently falls back to the user data partition, which the SPL misses.

To learn about the actual boot source anyway, we repeat the algorithm
the BROM used to select the boot partition in the first place:
- Test EXT_CSD[179] to check if an eMMC boot partition is enabled.
- Test EXT_CSD[177] to check for valid MMC interface settings.
- Check if BOOT_ACK is enabled.
- Check the beginning of the first sector for a valid eGON signature.
- Load the whole SPL.
- Recalculate the checksum to verify the SPL is valid.

If one of those steps fails, we bail out and continue loading from the
user data partition. Otherwise we load from the selected boot partition.

Since the boot source is needed twice in the boot process, we cache the
result of this test to avoid doing this costly test multiple times.

This allows the very same image file to be put onto an SD card, into the
eMMC user data partition or into the eMMC boot partition, and safely
loads the whole of U-Boot from there.

92e46092f2 arch: arm: mach-k3: am642_init: Probe ESM nodes
On AM64x devices, it is possible to route Main ESM0 error events to MCU
ESM. MCU ESM high error output can trigger the reset logic to reset the

 When these ESM device nodes are properly configired it is possible to
route the Main RTI0 WWDT output to the MCU ESM high output through Main
ESM and trigger a device reset when
CTRLMMR_MCU_RST_CTRL:MCU_ESM_ERROR_RESET_EN_Z is set to '0'.

On K3 AM64x devices, the R5 SPL u-boot handles the ESM device node

f8a1b33889 board: starqltechn: get board usable - add bootcmd and docs
U-boot is intended to replace linux kernel in android boot image(ABL), and
it's FIT payload to replace initramfs file. The boot process is similar to
boot image with linux:
- android bootloader (ABL) unpacks android boot image
- ABL sets `linux,initrd-start property` in chosen node in unpacked FDT
- ABL sets x0 register to FDT address, and passes control to u-boot
- u-boot reads x0 register, and stores it in `prevbl_fdt_addr` env variable
- u-boot reads `linux,initrd-start` property,
and stores it in `prevbl_initrd_start_addr`

In this way, u-boot bootcmd relies on `prevbl_initrd_start_addr` env
variable, and boils down to `bootm $prevbl_initrd_start_addr`.
If more control on boot process is desired, pack a boot script in
FIT image, and put it to default configuration

What done:
- strip unneeded config options
- add FIT image support
- add framebuffer node, u-boot logo and video console
- increase LMB_MAX_REGIONS, to store all linux dtb reserved memory regions
- add linux kernel image header

Uart driver causes hang, when u-boot is used in android boot image instead
of linux. Temporary disable console driver, until investigated and fixed.

12a3e1ada0 arm: init: save previous bootloader data
When u-boot is used as a chain-loaded bootloader (replacing OS kernel),
previous bootloader leaves data in RAM, that can be reused.

For example, on recent arm linux system, when chainloading u-boot,
there are initramfs and fdt in RAM prepared for OS booting. Initramfs
may be modified to store u-boot's payload, thus providing the ability to
use chainloaded u-boot to boot OS without any storage support.

Two config options added:
- SAVE_PREV_BL_INITRAMFS_START_ADDR
  saves initramfs start address to 'prevbl_initrd_start_addr' environment
  variable
- SAVE_PREV_BL_FDT_ADDR
  saves fdt address to 'prevbl_fdt_addr' environment variable

bbe310cdaf arm64: Catch non-emulated semihosting calls
If a debugger is not attached to U-Boot, semihosting calls will raise a
synchronous abort exception. Try to catch this and disable semihosting
so we can e.g. use another uart if one is available. In the immediate
case, we return an error, since it is not always possible to check for
semihosting beforehand (debug uart, user-initiated load command, etc.)

We handle all possible semihosting instructions, which is probably
overkill. However, we do need to keep track of what instruction set
we're using so that we don't suppress an actual error.

A future enhancement could try to determine semihosting capability by
inspecting the processor state.  There's an example of this at [1] for
RISC-V. The equivalent for ARM would inspect the monitor modei
enable/select bits of the DSCR. However, as the article notes, an
exception handler is still helpful in order to catch disconnected
debuggers.

385d69d76b arm: smh: Add option to detect semihosting
These functions are intended to support detecting semihosting and
falling back gracefully to alternative implementations. The test starts
by making semihosting call. SYS_ERRNO is chosen because it should not
mutate any state. If this semihosting call results in an exception
(rather than being caught by the debugger), then the exception handler
should call disable_semihosting() and resume execution after the call.

Ideally, this would just be part of semihosting by default, and not a
separate config. However, to reduce space ARM SPL doesn't include
exception vectors by default. This means we can't detect if a
semihosting call failed unless we enable them. To avoid forcing them to
be enabled, we use a separate config option. It might also be possible
to try and detect whether a debugger has enabled (by reading HDE from
DSCR), but I wasn't able to figure out a way to do this from all ELs.

This patch just introduces the generic code to handle detection. The
next patch will implement it for arm64 (but not arm32).

the simple case seems to work OK for now.

To control the presence of this boot method, we add a config symbol.
While we're at it, we update the original semihosting config symbol.

I think semihosting has some advantages of other forms of JTAG boot.
Common other ways to boot from JTAG include:

- Implementing DDR initialization through JTAG (typically with dozens of
  lines of TCL) and then loading U-Boot. The DDR initialization
  typically uses hard-coded register writes, and is not easily adapted
  to different boards. BOOT_DEVICE_SMH allows booting with SPL,
  leveraging U-Boot's existing DDR initialization code. This is the
  method used by NXP's CodeWarrior IDE on Layerscape processors (see
  AN12270).
- Loading a bootloader into SDRAM, waiting for it to initialize DDR, and
  then loading U-Boot. This is tricky, because the debugger must stop the
  boot after the bootloader has completed its work. Trying to load
  U-Boot too early can cause failure to boot. This is the method used by
  Xilinx with its Zynq(MP) processors.
- Loading SPL with BOOT_DEVICE_RAM and breaking before SPL loads the
  image to load U-Boot at the appropriate place. This can be a bit
  tricky, because the load address is dependent on the header size. An
  elf with symbols must also be used in order to stop at the appropriate
  point. BOOT_DEVICE_SMH can be viewed as an extension of this process,
  where SPL automatically stops and tells the host where to place the
  image.

8d78a6b674 vexpress64: Add ARMv8R-64 board variant
The ARMv8-R64 architecture introduces optional VMSA (paging based MMU)
support in the EL1/0 translation regime, which makes that part mostly
compatible to ARMv8-A.

Add a new board variant to describe the "BASE-R64" FVP model, which
inherits a lot from the existing v8-A FVP support. One major difference
is that the memory map in "inverted": DRAM starts at 0x0, MMIO is at
2GB [1].

 * Create new TARGET_VEXPRESS64_BASER_FVP target, sharing most of the
   exising configuration.
 * Implement inverted memory map in vexpress_aemv8.h
 * Create vexpress_aemv8r defconfig
 * Provide an MMU memory map for the BASER_FVP
 * Update vexpress64 documentation

At the moment the boot-wrapper is the only supported secure firmware. As
there is no official DT for the board yet, we rely on it being supplied
by the boot-wrapper into U-Boot, so use OF_HAS_PRIOR_STAGE, and go with
a dummy DT for now.

8a0a8ff52c vexpress64: fvp: add distro_boot support
So far the FVP model just supports booting through semihosting, so by
loading files from the host the model is running on. This allows for
quick booting of new kernels (or replacing DTBs), but prevents more
featureful boots like using UEFI.

Enable the distro_boot feature, and provide a list of possible boot
sources that U-Boot should check:
- For backwards compatibility we start with semihosting, which gets its
  commands migrated from CONFIG_BOOTCOMMAND into the distro_boot
  infrastructure. This is also slightly tweaked to fail graceful in case
  the required files could not be found.
- Next we try to use a user provided script, that could be easily
  placed into memory using the model command line.
- Since we gained virtio support with the enablement of OF_CONTROL,
  let's check virtio block devices next. This is where UEFI boot can
  be easily used, for instance by providing a distro installer .iso
  file through virtio-blk.
- Networking is now provided by virtio as well, so enable the default
  PXE and DHCP boot flows, mostly because we can.

c0fce92956 vexpress64: fvp: enable OF_CONTROL
The FVP base model is relying on a DT for Linux operation, so there is
no reason we would need to rely on hardcoded information for U-Boot.
Letting U-Boot use a DT will open up the usage of actual peripherals,
beyond the support for semihosting only.

Enable OF_CONTROL in the Kconfig, and use the latest dts files from
Linux. Depending on whether we use the boot-wrapper or TF-A, there is
already a DTB provided or not, respectively.

To cover the boot-wrapper, we add an arm64 Linux kernel header, which
allows the boot-wrapper to treat U-Boot like a Linux kernel. U-Boot will
find the pointer to the DTB in x0, and will use it.

Even though TF-A carries a DT, at the moment this is not made available
to non-secure world, so to not break users, we use the U-Boot provided
DTB copy in that case. For some reason TF-A puts some DT like structure
at the address x0 is pointing at, but that is very small and doesn't
carry any hardware information. Make the code to ignore those small DTBs.

fac7fc43cf vexpress64: Kconfig: move board definitions out of arch/arm
At the moment we define three "VExpress64" boards in arch/arm/Kconfig,
plus have a second Kconfig file in board/armltd/Kconfig.
One of those three boards is actually bogus (TARGET_VEXPRESS64_AEMV8A),
that stanza looks like being forgotten in a previous cleanup.

To remove the clutter from the generic Kconfig file, just define some
ARCH_VEXPRESS64 symbol there, enable some common options, and do the
board/model specific configuration in the board/armltd Kconfig file.

That allows to streamline and fine tune the configuration later, and
to also pull a lot of "non user choices" out of the defconfigs.

f206af80f8 ARM: at91: sama7g5: Reset external devices at software reset
sama7g5 and other SoCs (sama5d3, sam9x60) define in the Reset Controller
a RSTC_CR.EXTRST bit that asserts the nrst_out pin which resets external
devices.

This is particular useful for external devices that are configured in
stateful modes which can not be undone without reconfiguring the device
or without resetting the device. An example is an SPI NOR flash that is
configured in octal mode. The do_reset u-boot cmd does not call any
driver's remove method, but merely resets the CPU. As the code was, this
left the flash in octal mode, being impossible for the first stage boot
loaders to recover/identify the flash after a "software reset".
RSTC_CR.EXTRST comes in handy here, as it can be set at "software reset"
to assert low the nrst_out pin during a time defined by the RSTC_MR.ERSTL
field and reset the external devices (including the SPI NOR flash in the
example).
nrst_out is always asserted at "user reset" and it resets the external
devices correctly. Asserting nrst_out at "software reset" should behave
in a similar way. The only difference that I could find between the two
types of resets in regards to the nrst_out signal, is that at "user reset"
timing diagram the "Processor and Peripherals Reset Line" rises after six
MD_SLCK cycles after the nrst_out line rose, while at the "software reset"
timing diagram the "Processor and Peripherals Reset Line" is active for
3 MD_SLCK cycles + 2 MCK cycles. In other words, in the "software reset"
case the nrst_out signal can be active for a longer period of time than the
"Processor and Peripherals Reset Line" active time, depending on the
RSTC_MR.ERSTL value.
Using the default value (zero) for RSTC_MR.ERSTL, worked just fine for the
sama7g5 case. Tested QSPI0 and GMAC0/GMAC1 on sama7g5ek rev 4 after a
software reset with RSTC_CR.EXTRST=1 and RSTC_MR.ERSTL=0.

Since Ethernet is of no use in the SPL anyway, just move the call into

8285b928c5 arm: a37xx: espressobin: Fix non-working SPI
Commit 0934dddc64 ("arm: a37xx: Update DTS files to version from
upstream Linux kernel") ported Linux's device-tree files for Armada 3720
SOCs. This broke SPI support on some Espressobin boards and results in
following U-Boot error:

  Loading Environment from SPIFlash... jedec_spi_nor flash@0: unrecognized JEDEC id bytes: f7, 30, 0b
  *** Warning - spi_flash_probe_bus_cs() failed, using default environment

Before that commit DT node for SPI was called 'spi-flash@0' and after
that commit it is called 'flash@0'. Before that commit 'spi-max-frequency'
was set to 50000000 and after it is 104000000.

Rename DT node 'spi-flash@0 in armada-3720-espressobin-u-boot.dtsi to
'flash@0' and set custom U-Boot 'spi-max-frequency' back to 50000000.

With this change SPI is working on Espressobin again and it is detected
with JEDEC ids ef, 60, 16 on our tested unit.

  Loading Environment from SPIFlash... SF: Detected w25q32dw with page size 256 Bytes, erase size 4 KiB, total 4 MiB
  OK

Note that it is unknown why spi-max-frequency with value 104000000 does not
work in U-Boot as it works fine with Linux kernel. Also note that in
defconfig file configs/mvebu_espressobin-88f3720_defconfig is set option
CONFIG_SF_DEFAULT_SPEED=40000000 which is different value than in DT.

Commit 0934dddc64 ("arm: a37xx: Update DTS files to version from

For now, fix this by adding `vbus-supply` to usb3 node.

b42297ba81 rockchip: Set default LNX_KRNL_IMG_TEXT_OFFSET_BASE to SYS_TEXT_BASE
U-Boot can be chainloaded from vendor firmware on ARM64 chromebooks from
a GPT partition (roughly the same as in doc/chromium/chainload.rst), but
an appropriate image header must be built-in to the U-Boot binary by
enabling LINUX_KERNEL_IMAGE_HEADER.

This header has a field for an image load offset from 2MiB alignment
which must also be customized through LNX_KRNL_IMG_TEXT_OFFSET_BASE.
Set it equal to SYS_TEXT_BASE by default for Rockchip boards, which
happens to make this offset zero and works fine on chromebook_kevin
both for chainloading and bare-metal use.

6d36e92d28 rockchip: rk3399: Add support for chromebook_kevin
Add support for Kevin, an RK3399-based convertible chromebook that is
very similar to Bob. This patch is mostly based on existing support for
Bob, with only minor changes for Kevin-specific things.

Unlike other Gru boards, coreboot sets Kevin's center logic to 925 mV,
so adjust it here in the dts as well. The rk3399-gru-kevin devicetree
has an unknown event code reference which has to be defined, set it
to the Linux counterpart. The new defconfig is copied from Bob with the
diffconfig:

     DEFAULT_DEVICE_TREE "rk3399-gru-bob" -> "rk3399-gru-kevin"
     DEFAULT_FDT_FILE "rockchip/rk3399-gru-bob.dtb" -> "rockchip/rk3399-gru-kevin.dtb"
     VIDEO_ROCKCHIP_MAX_XRES 1280 -> 2400
     VIDEO_ROCKCHIP_MAX_YRES 800 -> 1600
    +TARGET_CHROMEBOOK_KEVIN y

With this Kevin can boot from SPI flash to a usable U-Boot prompt on the
display with the keyboard working, but cannot boot into Linux for
unknown reasons.

eMMC starts in a working state but fails to re-init, microSD card works
but at a lower-than-expected speed, USB works but causes a hang on
de-init. There are known workarounds to solve eMMC and USB issues.

8ba1ade3f8 rockchip: gru: Add more devicetree settings
This adds some devicetree settings for the Gru-based boards, based on
what works on a Kevin board.

Gru-based boards usually have an 8MiB SPI flash chip and boot from it.
Make the u-boot.rom file intended to be flashed on it match its size.
Add properties for booting from SPI, and only try to boot from SPI as
MMC and SD card don't seem to work in SPL yet.

The Chromium OS EC needs a delay between transactions so it can get
itself ready. Also it currently uses a non-standard way of specifying
the interrupt. Add these so that the EC works reliably.

The Rockchip Embedded DisplayPort driver is looking for a rockchip,panel
property to find the panel it should work on. Add the property for the
Gru-based boards.

The U-Boot GPIO controlled regulator driver only considers the
"enable-gpios" devicetree property, not the singular "enable-gpio" one.
Some devicetree source files have the singular form as they were added
to Linux kernel when it used that form, and imported to U-Boot as is.
Fix one instance of this in the Gru boards' devicetree to the form that
works in U-Boot.

The PWM controlled regulator driver complains that there is no init
voltage set for a regulator it drives, though it's not clear which one.
Set them all to the voltage levels coreboot sets them: 900 mV.

The RK3399 SoC needs to know the voltage level that some supplies
provides, including one fixed 1.8V audio-related regulator. Although
this synchronization is currently statically done in the board init
functions, a not-so-hypothetical driver that does this dynamically would
query the regulator only to get -ENODATA and be confused. Make sure
U-Boot knows this supply is at 1.8V by setting its limits to that.

Most of this is a reapplication of commit 08c85b57a5 ("rockchip: gru:
Add extra device-tree settings") whose changes were removed during a
sync with Linux at commit 167efc2c7a ("arm64: dts: rk3399: Sync
v5.7-rc1 from Linux"). Apply things to rk3399-gru-u-boot.dtsi instead so
they don't get lost again.

351729ca44 arm: mvebu: dts: turris_mox: fix non-working network / MDIO
Commit 0934dddc64 ("arm: a37xx: Update DTS files to version from
upstream Linux kernel") ported Linux's device-tree files for Armada 3720
SOCs. This broke network on Turris MOX, because the SOC's MDIO bus in
U-Boot currently isn't probed via DM as it's own device, but is
registered as part of mvneta's driver, which means that pinctrl
definitions are not parsed for the MDIO bus node. Also mvneta driver
does not consider "phy-handle" property, only "phy".

For now, fix this by adding armada-3720-turris-mox-u-boot.dtsi file
returning the MDIO to how it was defined previously.

A better solution (using proper mvmdio DM driver) is being work on, but
will need testing on various boards, and we need the bug fixed now for
the upcoming release.

19fbe102b2 ARM: dts: stm32: Add DFU support for DHCOM recovery
This patch configures U-Boot SPL for DHCOM SoM to permit DFU upload of
SPL and subsequent u-boot.itb for recovery or commissioning purposes.

The DFU usage procedure is identical to STM32MP1 DHCOR SoM, see commit
3919aa1722 ("ARM: dts: stm32: Add DFU support for DHCOR recovery") ,
except for switching the SoM into DFU mode. By default, the DHCOM SoM
has no dedicated mechanism for setting BOOTn straps into UART/USB mode,
therefore to enter DFU mode, the SoC must fail to boot from boot media
which can be selected by the BOOTn strap override mechanism first and
then fall back to DFU mode.

In case of a SoM with pre-populated BOOTn strap override button, power
the system off, remove microSD card (if applicable), hold down the BOOTn
strap override button located between eMMC and SoM edge connector, power
on the SoM. The SoC will fail to boot from SD card and fall back into
DFU mode.
