Now that it is possible to use regulator-fixed-clock make use

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.

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

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.

Merge tag 'u-boot-at91-2022.07-a' of https://source.denx.de/u-boot/custodians/u-boot-at91 into next
First set of u-boot-at91 features for the 2022.07 cycle:
This feature set includes the new driver for the Atmel TCB timer,
alignment in DT for sama7g5 and sama7g5ek board, one Kconfig conversion
for external reset, and the usage of Galois tables from ROM for sama5d2
device.
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.

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.

The kernel DTs got updated over the last few months, but we were missing

*** Warning - spi_flash_probe_bus_cs() failed, using default environment
Before that commit DT node for SPI was called 'spi-flash@0' and after

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

With this Kevin can boot from SPI flash to a usable U-Boot prompt on the

unknown reasons.

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

This patch configures U-Boot SPL for DHCOM SoM to permit DFU upload of

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 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.

With limited low level configuration done via psu-init only IPs connected

The default U-Boot environment variables and design are all set up for
the MAIN R5FSS cluster to be in Split-mode. This is the setting used
when the dts nodes were originally added in v2021.01 U-Boot and the
dt nodes are synched with the kernel binding property names in
commit 468ec2f3ef ("remoteproc: k3_r5: Sync to upstreamed kernel DT
property names") merged in v2021.04-rc2.
The modes for the MAIN R5FSS cluster got switched back to LockStep mode
by mistake in commit fa09b12dc5 ("arm: ti: k3: Resync dts files and
bindings with Linux Kernel v5.14") in v2022.01-rc1. This throws the
following warning messages when early-booting the cores using default

Load Remote Processor 3 with data@addr=0x82000000 83148 bytes: Failed!
Fix this by switching back both the clusters to the expected Split-mode.
Make this mode change in the u-boot specific dtsi file to avoid such
sync overrides in the future until the kernel dts is also switched to
Split-mode by default.
