d5cc234154 arm: dts: imx8m*-venice: add gpio hog support
Add gpio hog support for board-specific gpio lines:
- put hogs in u-boot.dtsi so as to keep the regular dts files
  in sync with the kernel. The hogs will not be put in the kernel
  as that makes them un-usable by userspace as well as
  re-initializes them to dt defaults overriding changes which may
  have been done by bootloader commands.
- specify gpio names and initial config
- enable GPIO_HOG

8b3d7ecdfe arm: mvebu: Add support for reading LD0 and LD1 eFuse
Armada 385 contains 64 lines of HD eFuse and 2 lines of LD eFuse. HD eFuse
is used for secure boot and each line is 64 bits long + 1 lock bit. LD
eFuse lines are 256 bits long + 1 lock bit. LD 0 line is reserved for
Marvell Internal Use and LD 1 line is for General Purpose Data. U-Boot
already contains HD eFuse reading and programming support.

This patch implements LD eFuse reading support. LD 0 line is mapped to
U-Boot fuse bank 64 and LD 1 line to fuse bank 65.

LD 0 Marvell Internal Use line seems that was burned in factory with some
data and can be read by U-Boot fuse command:

  => fuse read 64 0 9

LD 1 General Purpose Data line is by default empty and can be read by
U-Boot fuse command:

  => fuse read 65 0 9

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.

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.

cb61b2fb2b ARM: imx: Get rid of only i.MX8M SMCCC arch call
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

By removing this one instance of SMCCC call, U-Boot no longer depends

d072fdde53 ARM: imx: romapi: Repair FlexSPI NOR boot offset
The FlexSPI NOR boot offset does not require any special handling,
the image_offset is correct in either case (0x1000 for FlexSPI NOR
and 0x8000 for SD/eMMC) and the offset of u-boot.itb from the start
of flash.bin is always 0x58000 on MX8MN/MX8MP, which matches the
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR * 512 - 0x8000 in case
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR=0x300, which is always the
case on MX8MN/MX8MP.

The CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR is really overloaded in
case of the MX8MN/MX8MP, but fixing that needs additional plumbing.

Turns out on certain carrier boards (e.g. Iris V2) and under certain
circumstances (e.g. after a software reset) the SD card may have been
left in a strange state which later failed as follows:

Colibri iMX6ULL # mmc dev 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
how it is done in mx6ullevk.c

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.
If you rely on very fast boot-speeds and don't need ethernet
for your boot-process you can safely revert the changes on

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).

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
device. So, for these devices we expect two ESM device nodes in the
device tree, one for Main ESM and the another MCU ESM in the device tree.
 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).

8e1c9fe243 spl: Add semihosting boot method
This adds a boot method for loading the next stage from the host. It is
mostly modeled off of spl_load_image_ext. I am not really sure why/how
spl_load_image_fat uses three different methods to load the image, but
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.

One of those three boards is actually bogus (TARGET_VEXPRESS64_AEMV8A),

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

Add a driver for the timer counter block that can be found on sama5d2.
This driver will be used when booting under OP-TEE since the pit timer
which is part of the SYSC is secured. Channel 1 & 2 are configured to
be chained together which allows to have a 64bits counter.

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.

The kernel DTs got updated over the last few months, but we were missing
out on the U-Boot version.

Just sync in the phy-mode properties from the mainline kernel,
v5.17-rc7, to avoid the breaking DT sync that late in the cycle.

Commit 5bc4cd05d7 ("sunxi: move non-essential code out of s_init()")

This means it's now only called from the SPL, which makes sense for
most of the other moved low-level functions. However the GMAC pinmux and
clock setup in eth_init_board() was not happy about that, so it broke
the sun7i GMAC.

Since Ethernet is of no use in the SPL anyway, just move the call into
board_init(), which is only run in U-Boot proper.

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.

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.

81a46c152a sunxi: Kconfig: Fix up SPI configuration
Commit 7945caf22c ("arm: sunxi: Enable SPI/SPI-FLASH support for A64")
selected CONFIG_SPI by default on all Allwinner A64 boards, even though
only 4 out of the 14 A64 boards have a SPI flash chip. All other SoCs
had to manually select DM_SPI and friends, even though they are a
platform property (the sunxi SPI driver is DM_SPI only).

Clean this up to allow easy selection of SPI flash support in U-Boot
proper, by selecting DM_SPI and DM_SPI_FLASH *if* CONFIG_SPI is
selected, for *all* Allwinner SoCs. This simplifies the defconfig for
two Libretech boards already.

Also remove the forced CONFIG_SPI from the A64 Kconfig, instead let the
four boards which allow SPI booting select this explicitly.

Any board wishing to support SPI flash in U-Boot proper now just defines
CONFIG_SPI and CONFIG_SPI_FLASH_<vendor> in its defconfig, Kconfig takes
care of the rest.

8b82a3a7fe arm64: zynqmp: Enable DP driver for SOMs
The main reason is to send pmufw cfg overlay from U-Boot to PMUFW to enable
access to DP. Overlay is sent when cls command is called and for that IP
has to be enabled in carrier cards.
And IP needs to be also enabled in SOM dt because with DTB reselection new
DT is not parsed in pre reloc U-Boot instance. It is called from board_f
via embedded_dtb_select(). That's why bind function is not able to allocate
memory and it ends up with error:
"Video device 'display@fd4a0000' cannot allocate frame buffer memory
-ensure the device is set up before relocation"

To avoid this situation DP is placed also to SOM where bind function is
called and frame buffer memory is allocated and just reused after DTB
reselection. Result is the same. There could be a problem in Linux with
different DP configurations but that's need to be solved there because
console should be on from u-boot already.

c36dc2449b arm64: zynqmp: Move usb hub from i2c to usb node
Based on upstream discussion based on link below usb hub should be placed
to usb node directly as child node. Based on this Linux driver was updated
and the same change should be also reflected in kv260 board.

39834ccdd4 arm: dts: iot2050: Add cfg register space for ringacc and udmap
Recent unrelated fixes (9876ae7db6) revealed that we were missing bits
from 2af181b53e in the IOT2050 dt. Add them, but only for main U-Boot.
SPL loads from QSPI only, thus cannot use DMA.

f7fbe547d9 arm: mach-k3: am6_init: Use CONFIG_TI_I2C_BOARD_DETECT
We only want to call do_board_detect() if CONFIG_TI_I2C_BOARD_DETECT
is set. Same as done for am64.

This makes it possible to add a custom am65 based board design to
U-Boot that does not use this board detection mechanism.

1fd54253bc arm: a37xx: pci: Fix a3700_fdt_fix_pcie_regions() function again
The a3700_fdt_fix_pcie_regions() function still computes nonsense.

It computes the fixup offset from the PCI address taken from the first
row of the "ranges" array, which means that:
- PCI address must equal CPU address (otherwise the computed fix offset
  will be wrong),
- the first row must contain the lowest address.

This is the case for the default device-tree, which is why we didn't
notice it.

It also adds the fixup offset to all PCI and CPU addresses, which is
wrong.

Instead:
1) The fixup offset must be computed from the CPU address, not PCI
   address.

2) The fixup offset must be computed from the row containing the lowest
   CPU address, which is not necessarily contained in the first row.

3) The PCI address - the address to which the PCIe controller remaps the
   address space as seen from the point of view of the PCIe device -
   must be fixed by the fix offset in the same way as the CPU address
   only in the special case when the CPU adn PCI addresses are the same.
   Same addresses means that remapping is disabled, and thus if we
   change the CPU address, we need also to change the PCI address so
   that the remapping is still disabled afterwards.

Consider an example:
  The ranges entries contain:
    PCI address   CPU address
    70000000      EA000000
    E9000000      E9000000
    EB000000      EB000000

  By default CPU PCIe window is at:        E8000000 - F0000000
  Consider the case when TF-A moves it to: F2000000 - FA000000

  Until now the function would take the PCI address of the first entry:
  70000000, and the new base, F2000000, to compute the fix offset:
  F2000000 - 70000000 = 82000000, and then add 8200000 to all addresses,
  resulting in
    PCI address   CPU address
    F2000000      6C000000
    6B000000      6B000000
    6D000000      6D000000
  which is complete nonsense - none of the CPU addresses is in the
  requested window.

  Now it will take the lowest CPU address, which is in second row,
  E9000000, and compute the fix offset F2000000 - E9000000 = 09000000,
  and then add it to all CPU addresses and those PCI addresses which
  equal to their corresponding CPU addresses, resulting in
    PCI address   CPU address
    70000000      F3000000
    F2000000      F2000000
    F4000000      F4000000
  where all of the CPU addresses are in the needed window.
