f9e2d9e889 arm: dts: rockchip: rk3399-roc-pc: Enable FE1.1 USB 2.0 HUB on roc-rk3399-pc
roc-rk3399-pc has an FE1.1 USB 2.0 HUB which connects two USB ports
(HOST1 and HOST2). For end devices to work we need to enable USB hub
so that HOST detects there presence and enumerates them accordingly.
This requires explicit pinctrl within gpio enablement.

3fd0231432 mips: Add support for SoM "VoCore2".
Small patch to add support for VoCore/VoCore2 board.

VoCore is open hardware and runs OpenWrt/LEDE.
It has WIFI, USB, UART, 20+ GPIOs but is only one inch square.
It will help you to make a smart house, study embedded system
or even make the tiniest router in the world.

Details about this SoM can be found at "https://vocore.io/v2.html".

04d21a93fa mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations
The current implementations have some issues detecting the correct
values:

dqs_find_max() will return "last passing fieldval + 1" instead of
"last passing fieldval". Also it will return "maxval + 1" in the
case that all fieldvals are tested valid (without error).

dqs_find_min() will not test the "lowest" value because of using ">"
instead of ">=".

This patch now rewrites these functions to fix those issues. Also,
this patch uses the same approach of a for loop in both functions making
it easier to read and maintain.

Since the variables are integers now, we can use min()/max(), which
handles the wrap around case for fieldval=0: return (0 - 1).

7a4b6964b5 mips: mtmips: add SPL support
This patch adds SPL support for mtmips platform. The lowlevel architecture
is split into SPL and the rest parts are built into a memory loadable
u-boot image. Optional SPL_DM and OF_CONTROL are also supported.

The increment of size is very small (< 10 KiB) if SPL_DM and OF_CONTROL are
not enabled and the memory bootable u-boot (u-boot.img) is generated
automatically so there is not need to add a separate config for it.

A lzma compressed payload (u-boot-lzma.img) is also generated and it will
be combined with u-boot-spl.bin to form the unified ROM bootable binary
u-boot-mtmips.bin.

A spl loader is added to support uncompress the payload.

3. Reimplement DDR initialization in C language.
4. Reimplement DDR calibration in a clear logic.
5. Add full support for auto size detection for DDR1 and DDR2.
6. Use accurate CPU clock depending on the input xtal frequency for timer

a60c1e6d6b mips: add a mtmips-specific field to architecture-specific global data
SoCs of mtmips can use different CPU frequencies depending on the HW/SW
configurations. For example mt7628 uses 580MHz clock if the input xtal
frequency is 40MHz, and 575MHz clock if the xtal is 25MHz. Upon cold boot
the CPU uses the xtal frequency directly.

So hardcoding the timer frequency (half of the CPU frequency) in
CONFIG_SYS_MIPS_TIMER_FREQ is not a good idea for this case.

This patch adds a mtmips-specific field timer_freq to arch_global_data.
This field will be used later in mtmips-specific get_tbclk() to provide
accurate timer frequency in different boot stage.

6e9281b559 mips: start.S: avoid overwriting outside gd when clearing global data in stack
When setting up initial stack, global data will also be put in the stack,
and being cleared.

The assembler instructions for clearing gd is as follows:

	move	t0, k0
1:
	PTR_S	zero, 0(t0)
	blt	t0, t1, 1b
	 PTR_ADDIU t0, PTRSIZE

t0 is the start address of gd, t1 is the end address of gd (t0 + GD_SIZE).

[PTR_ADDIU t0, PTRSIZE] is in the delay slot of [blt t0, t1, 1b], so it
will be executed before the branch operation.

However the comparison for the BLT instruction is done before executing the
delay slot. This means when the last word just before k1 is cleared, the
loop will continue to run once. This will clear an extra word at k1, which
is outside the global data.

Global data is placed at the top of the stack. If the initial stack is a
SRAM or locked cache, the area outside them may be inaccessible. A write
operation performed in this area may cause an exception.

To solve this, [PTR_ADDIU t0, PTRSIZE] should be placed before the BLT
instruction.

It is also highly recommended to configure the board for the DHCOM
make stm32mp15_dhcom_basic_defconfig
make DEVICE_TREE=stm32mp15xx-dhcor-avenger96
as that permits reusing the board code for the DH components, like
accessing and reading out the ethernet MAC from EEPROM.

e5899099ab ARM: dts: stm32: Adjust PLL4 settings on AV96
The PLL4 is supplying SDMMC12, SDMMC3 and SPDIF with 120 MHz and
FDCAN with 96 MHz. This isn't good for the SDMMC interfaces, which
can not easily divide the clock down to e.g. 50 MHz for high speed
SD and eMMC devices, so those devices end up running at 30 MHz as
that is 120 MHz / 4. Adjust the PLL4 settings such that both PLL4P
and PLL4R run at 100 MHz instead, which is easy to divide to 50MHz
for optimal operation of both SD and eMMC, SPDIF clock are not that
much slower and FDCAN is also unaffected.

d4ea649f17 riscv: Provide a mechanism to fix DT for reserved memory
In RISC-V, M-mode software can reserve physical memory regions
by setting appropriate physical memory protection (PMP) csr. As the
PMP csr are accessible only in M-mode, S-mode U-Boot can not read
this configuration directly. However, M-mode software can pass this
information via reserved-memory node in device tree so that S-mode
software can access this information.

This patch provides a framework to copy to the reserved-memory node
from one DT to another. This will be used to update the DT used by
U-Boot and the DT passed to the next stage OS.

ab2f757eb0 arm: mvebu: correct SPL boot configs for SPI/MMC
Update mvebu SPL boot selection mechanism for the move to driver model
usage by ensuring that the required driver support for SPI and MMC
booting is available in SPL when the respective boot method is
selected.

Previously, all mvebu boards selected a boot method (implicitly
MVEBU_SPL_BOOT_DEVICE_SPI for many) even if SPL booting wasn't used.
This changes mvebu boot method selection to depend on SPL usage which
resolves the issue with aarch64 boards which don't use SPL getting an
implicit boot device selection resulting in unmet dependencies. The
32-bit arm boards do use SPL, but I'm led to conclude that most aren't
intentionally using the MVEBU_SPL_BOOT_DEVICE selection since none have
SPL_DM_SPI enabled in their defconfig even though they still implicitly
select the SPI boot method.

This also results in the new addition of SPL_GPIO_SUPPORT to helios4.
The mainline dts for helios4 includes the cd-gpios entry for sdhci with
identical addresses as the clearfog dts. I don't have a helios4 board
to confirm, but based on the current source conclude that the board
itself is either wired to pull the signal low for eMMC, or the default
MMC boot isn't fully functional in mainline. In either case, as far as
I can tell, including the GPIO support will at least cause no
regression.

Tested on SolidRun ClearFog devices.

4a45f4046b dts: imx: Add fixed-link property to HSC and DDC (imx53) devices
Those two boards are supposed to be run with a single u-boot binary.
There are notable differences though - HSC uses DSA switch (which
phy_id == 0x0) and DCC (DP83848C).

After the commit 3bf135b6c3
("drivers: net: phy: Ignore PHY ID 0 during PHY probing") the PHY devices
with phy_id == 0 are not created in U-Boot anymore. This caused regression
on HSC.

To fix this problem - the fec's 'fixed-link' node has been introduced and
the phy_id is not assessed anymore. This approach works on both boards.

4c13a4db60 wandboard: Fix version detection for mx6q/mx6dl revD1
The detection of the revD1 version is based on the presence of the PMIC.

Currently revb1 device trees are used for mx6q/mx6dl variants, which
do not have the PMIC nodes.

This causes revD1 boards to be incorrectly be detected as revB1.

Fix this issue by using the revd1 device trees, so that the PMIC node can be
found and then the PMIC can be detected by reading its register ID.

Imported the revd1 device trees from mainline kernel version 5.7-rc1.

2960107a22 sandbox: also restore terminal settings when killed by SIGINT
Hitting Ctrl-C is a documented way to exit the sandbox, but it is not
actually equivalent to the reset command. The latter, since it follows
normal process exit, takes care to reset terminal settings and
restoring the O_NONBLOCK behaviour of stdin (and, in a terminal, that
is usually the same file description as stdout and stderr, i.e. some
/dev/pts/NN).

Failure to restore (remove) O_NONBLOCK from stdout/stderr can cause
very surprising and hard to debug problems back in the terminal. For
example, I had "make -j8" consistently failing without much
information about just exactly what went wrong, but sometimes I did
get a "echo: write error". I was at first afraid my disk was getting
bad, but then a simple "dmesg" _also_ failed with write error - so it
was writing to the terminal that was buggered. And both "make -j8" and
dmesg in another terminal window worked just fine.

So install a SIGINT handler so that if the chosen terminal
mode (cooked or raw-with-sigs) means Ctrl-C sends a SIGINT, we will
still call os_fd_restore(), then reraise the signal and die as usual
from SIGINT.

Before:

$ grep flags /proc/$$/fdinfo/1
flags:  0102002
$ ./u-boot
# hit Ctrl-C
$ grep flags /proc/$$/fdinfo/1
flags:  0106002

After:

$ grep flags /proc/$$/fdinfo/1
flags:  0102002
$ ./u-boot
# hit Ctrl-C
$ grep flags /proc/$$/fdinfo/1
flags:  0102002

this is used unchanged right through U-Boot.

At present the reading of this address is split between the ofdata() and
probe() methods. There are a few problems that are unique to the p2sb.
One is that its children need to call pcr_read32(), etc. which needs to
have the p2sb address correct. Also some of its children are pinctrl
devices and pinctrl is used when any device is probed. So p2sb really
needs to get its base address set up in ofdata_to_platdata(), before it is
probed.

Another point is that reading the p2sb BAR will not work if the p2sb is
hidden. The FSP-S seems to hide it, presumably to avoid confusing PCI
enumeration.

Reading ofdata in ofdata_to_platdata() is the correct place anyway, so
this is easy to fix.

Move the code into one place and use the early-regs property in all cases
for simplicity and to avoid needing to probe any PCI devices just to read
the BAR.

a129f64fb0 arm64: mvebu: a37xx: improve code determining memory info structures
Currently on Armada-37xx the mem_map structure is statically defined to
map first 2 GB of memory as RAM region, and system registers and PCIe
region device region.

This is insufficient for when there is more RAM or when for example the
PCIe windows is mapped to another address by the CPU Address Decoder.
In the case when the board has 4 GB RAM, on some boards the ARM Trusted
Firmware can move the PCIe window to another address, in order to
maximize possible usable RAM.

Also the dram_init and dram_init_banksize looks for information in
device-tree, and therefore different device trees are needed for boards
with different RAM sizes.

Therefore we add code that looks at how the ARM Trusted Firmware has
configured the CPU Address Decoder windows, and then we update the
mem_map structure and compute gd->ram_size and gd->bd->bi_dram bank
base addresses and sizes accordingly.

0db0ba6141 imx: Fix imx8m FIT script issue
The FIT config node has reversed ATF and u-boot: ATF is set to 'firmware' but
u-boot is set to 'loadables'.
This script can work previously because spl fit driver wrongly appends fdt to
all loadable images. With the issue fixed in commit 9d15d1d1c2 ("Revert
"common: spl_fit: Default to IH_OS_U_BOOT if FIT_IMAGE_TINY enabled"") the
u-boot in 'loadables' does not have fdt appended and fails to work.  So correct
the script by moving u-boot to 'firmware' and ATF to 'loadables'.

fb9acad305 mips: cmd: go: Flush cache before jumping to app/image
It has been noticed on MT7628/88 platforms, that booting the RAM image
does not work reliably. Sometimes it works and sometimes not. Debugging
showed that this "might" be a cache related issue as very strange
errors occurred (e.g. output corrupted etc).

This patch adds a cache flush for the complete SDRAM area to the go cmd
before jumping to the entry point for the MIPS architecture. The
complete area is flushed as we don't know at this point, how big the
area of the "application" really is.

7048bb13b2 mips: vcoreiii: Fix cache coherency issues
This patch fixes an stability issue seen on some vcoreiii targets,
which was root caused to a cache inconsistency situation.

The inconsistency was caused by having kuseg pointing to NOR area but
used as a stack/gd/heap area during initialization, while only
relatively late remapping the RAM area into kuseg position.

The fix is to initialize the DDR right after the TLB setup, and then
remapping it into position before gd/stack/heap usage.

Alternative software bootmode selection to JTAG is not working because JTAG
mode is 0 which also reset value for it. That's why saying SPL to take
u-boot.itb from RAM instead of SD in SD boot mode is not possible via

dacec83ce0 Makefile: Add environment variable DEVICE_TREE to header

(CONFIG_DEFAULT_DEVICE_TREE) via environment variable DEVICE_TREE.

Feature has been added long time ago by commit 74de8c9a16
("dts/Makefile: Build the user specified dts") for a little bit different
reason.

But this variable can be also used for different purpose like choosing
proper configuration from FIT image in SPL.
And this is the functionality I would like to use on Xilinx Zynq devices
that current u-boot.img can be composed in the same way based on OF_LIST
and different configuration is taken based on platform specific SPL.
SPL requires low level ps7_init_gpl configuration that's why different
boards require different SPL with fixed board_fit_config_name_match().

For this the mtd devices are registered as read-only NVMEM providers
under sysfs with the same name as the flash partition label property.

So if flash partition label property of multiple flash devices are identical
then the second mtd device fails to get registered as a NVMEM provider.

This patch fixes the issue by having different label property for different

e14ba8a577 arch: Add explicit linker script for u-boot-elf
Commit f4dc714aaa ("arm64: Turn u-boot.bin back into an ELF file after
relocate-rela")
introduce REMAKE_ELF option to recreate u-boot.elf from u-boot ->
u-boot.bin + DT -> u-boot.elf.

The best is to ilustrate it from make V=1 output
  cat u-boot-nodtb.bin dts/dt.dtb > u-boot-dtb.bin
  cp u-boot-dtb.bin u-boot.bin
aarch64-linux-gnu-objcopy -I binary -B aarch64 -O elf64-littleaarch64  u-boot.bin u-boot-elf.o
  aarch64-linux-gnu-ld.bfd u-boot-elf.o -o u-boot.elf --defsym="_start"=0x8000000 -Ttext=0x8000000

Last command has no explicit linker script passed that's why toolchain
internal linker script is used.
In Binutils 2.32 case it contains SIZEOF_HEADERS symbol which has changed
behavior by commit
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=64029e93683a266c38d19789e780f3748bd6a188
which result in situation that program headers has changed from
(xilinx_zynqmp_mini_defconfig)

Program Headers:
  Type           Offset             VirtAddr           PhysAddr
                 FileSiz            MemSiz              Flags  Align

to

Xilinx tools like XSDB or Bootgen are using program headers for loading ELF
to the right location and by above binutils change ELF is loaded to
incorrect location.

The patch is explicitly use u-boot-elf.lds (just cat now) for u-boot.elf
recreation which is called when REMAKE_ELF is setup.
By purpose u-boot-elf.lds doesn't contain OUTPUT_FORMAT/OUTPUT_ARCH to be
able to use by all archs.

HDMI 2.0 or DP 1.2 are available for display, four USB ports (3 USB 2.0
and 1 USB 3.0) can be used to attach a variety of peripherals and a PCI
Ethernet controller provides onboard network connectivity. NVMe support
has also been added. Env save is at the end of QSPI (4MB-8K).

a482f32992 mmc: t210: Fix 'bad' SD-card clock when doing 400KHz card detect
According to the HW team, for some reason the normal clock select code
picks what appears to be a perfectly valid 375KHz SD card clock, based
on the CAR clock source and SDMMC1 controller register settings (CAR =
408MHz PLLP0 divided by 68 for 6MHz, then a SD Clock Control register
divisor of 16 = 375KHz). But the resulting SD card clock, as measured by
the HW team, is 700KHz, which is out-of-spec. So the WAR is to use the
values given in the TRM PLLP table to generate a 400KHz SD-clock (CAR
clock of 24.7MHz, SD Clock Control divisor of 62) only for SDMMC1 on
T210 when the requested clock is <= 400KHz. Note that as far as I can
tell, the other requests for clocks in the Tegra MMC driver result in
valid SD clocks.

but it gets reset when the SDMMC1 HW is soft-reset during SD driver

e67243f1a3 video: rockchip: Fix vop modes for rk3399
VOP display endpoint pipeline configuration differs
between rk3288 vs rk3399.

These VOP pipeline configuration depends on how the
different display interfaces connected in sequence to
IN and OUT ports like for,

RK3288:

vopb_out: port {
	#address-cells = <1>;
	#size-cells = <0>;
	vopb_out_edp: endpoint@0 {
		reg = <0>;
		remote-endpoint = <&edp_in_vopb>;
	};
	vopb_out_hdmi: endpoint@1 {
		reg = <1>;
                remote-endpoint = <&hdmi_in_vopb>;
        };
        vopb_out_lvds: endpoint@2 {
                reg = <2>;
                remote-endpoint = <&lvds_in_vopb>;
        };
        vopb_out_mipi: endpoint@3 {
                reg = <3>;
                remote-endpoint = <&mipi_in_vopb>;
        };
};

RK3399:

vopb_out: port {
         #address-cells = <1>;
         #size-cells = <0>;
         vopb_out_edp: endpoint@0 {
                reg = <0>;
                remote-endpoint = <&edp_in_vopb>;
         };
         vopb_out_mipi: endpoint@1 {
                reg = <1>;
                remote-endpoint = <&mipi_in_vopb>;
         };
         vopb_out_hdmi: endpoint@2 {
                reg = <2>;
                remote-endpoint = <&hdmi_in_vopb>;
         };
         vopb_out_mipi1: endpoint@3 {
                reg = <3>;
                remote-endpoint = <&mipi1_in_vopb>;
         };
         vopb_out_dp: endpoint@4 {
                reg = <4>;
                remote-endpoint = <&dp_in_vopb>;
         };
};

here, HDMI interface has endpoint 1 in rk3288 and 2 in rk3399.

The rockchip vop driver often depends on this determined endpoint
number and stored in vop_mode. So based on this vop_mode the bpp
and pin polarity would configure on detected display interface.

Since, the existing driver using rk3288 vop mode settings enabling
the same will result wrong display interface configuration for rk3399.

Add the patch for fixing these vop modes for rk3399.

df7f49ca27 ARM: dts: stm32: Repair SDMMC2 operation
The eMMC uses different pinmux for the top four data lines, use such
a pinmux, otherwise it takes a very long time until the test for 8bit
operation times out. And this is the correct pinmux per schematic too.

81169ca3cc ARM: dts: stm32: Repair SD1 pre-reloc pinmux DT node on AV96
The sdmmc1_dir_pins_a: sdmmc1-dir-0 layout changed in commit 35a54d41d9
("ARM: dts: stm32mp1: sync device tree with v5.2-rc4") such that pins{};
became pins1{};pins2{};, however the SPL extras were not updated to reflect
that change. Fix this.

This fixes booting from SD1 X9 slot on the AV96 board.

7dbafe0634 Merge tag 'arc-last-minute-fixes-for-2020.04' of https://gitlab.denx.de/u-boot/custodians/u-boot-arc
This last minute pull-request is intended to fix some drivers
when used on ARC boards. The problem was introduced by
07906b3dad

What happened while doing one pretty simple improvement to make
U-Boot port more flexible and portable (by switching accessors from
assembly-written to plain C version) we implicitly added 2 problems:

 1. Downgraded accessors from being volatile which signalled to
    the compiler that it's now possible to do all kinds of optimizations
    which may easily include merge of subsequent byte reads/writes into
    word operations. Which is OK for accessing mormal memory but
    breaks operation of peripherals if we access its memory-mapped regs
    in such a "creative" manner.
 2. As a part of assembly-written implementation we had compiler barriers
    in form of the following construction 'asm volatile("" : : : "memory")',
    and we dropped it in C implemntation. This in its turn enabled compiler
    to mess with instruction ordering. Guess what it gives us in the end :)

So with all that we had in some corner-cases veeery funny instruction flows
generated. And in particular it broke DW SPI functionality when we were
writing large amount of data. Funny enough our tests which were writing
small amount of data still worked and only by the chance we caught that
breakage and unrolled that quite interesting loop of unexpected
problems.

The road to hell is paved with good intentions. Amen :)

45bd649511 ARC: IO: add MB for __raw_* memory accessors
We add memory barriers for __raw_readX / __raw_writeX accessors same
way as it is done for readX and writeX accessors as lots of U-boot
driver uses __raw_readX / __raw_writeX instead of proper accessor
with barrier.

It will save us from lot's of debugging in the future and it is OK
as U-Boot is not that performance oriented as real run-time
software like OS or user bare-metal app so we may afford being not
super fast as we only being executed once.

Add save_boot_params() to save reset status value from bootrom.

Bootrom will clear the status register in reset manager and stores the
reset status value in shared memory. Bootrom stores shared data at last
2KB of onchip RAM.

This function save reset status provided by bootrom to rst_mgr_status.
More information about reset status register value can be found in reset
manager register description.

When running in debugger without bootrom, r0 to r3 are random values.
So, skip save the value when r0 is not bootrom shared data address.
