47de135994 Merge branch '2022-01-07-imx8-and-buildman-updates'
- A large number of updates for i.MX8 platforms.  We update buildman /
  binman to be able to fake binaries if needed, for CI, and tell the user
  the binary won't work.  Update platforms to build again with these
  changes.

a89c8f2111 binman: add support for creating dummy files for external blobs
While converting to binman for an imx8mq board, it has been found that
building in the u-boot CI fails. This is because an imx8mq requires an
external binary (signed_hdmi_imx8m.bin). If this file cannot be found
mkimage fails.
To be able to build this board in the u-boot CI a binman option
(--fake-ext-blobs) is introduced that can be switched on via the u-boot
makefile option BINMAN_FAKE_EXT_BLOBS. With that the needed dummy files are
created.

75f080df46 Revert "clk: Detect failure to set defaults"
This reverts commit 92f1e9a4b3.
The aforementioned patch causes massive breakage on all platforms which
have 'assigned-clock' DT property in their DT which references any clock
that are not supported by the platform clock driver. That can easily
happen either in SPL, or because the clock driver is reduced. Currently
it seems all iMX8M are affected and fail to boot altogether.

f77549fe74 riscv: sifive: Fix OF_BOARD boot failure
When using QEMU to have a quick test of booting U-Boot S-mode payload
directly without the needs of preparing the SPI flash or SD card images
for SiFive Unleashed board, as per the instructions [1], it currently
does not boot any more.

This was caused by the OF_PRIOR_STAGE removal, as gd->fdt_blob no longer
points to a valid DTB. OF_BOARD is supposed to replace OF_PRIOR_STAGE,
hence we need to add the OF_BOARD logic in board_fdt_blob_setup().

- u-boot_kvim3l_ab.bin   : A/B support

Prepare a defconfig to support u-boot_kvim3_ab.bin and

This is identical to khadas-vim3{l}_ab_android but will be updated in

ede1f4f297 configs: amlogic: Disable CONFIG_NET_RANDOM_ETHADDR when unnecessary
On Meson GXL, GXM, AXG, G12A, G12B & SM1 SoCs, we can generate an unique
MAC address if none valid found in the eFuses storage.

Only the GXBB based boards doesn't have a fallback way to generate an
unique MAC address, so we rely on CONFIG_NET_RANDOM_ETHADDR to have
a valid one.

An exception is the Radxa Zero board who doesn't have Ethernet on board
so depends on an (or multiple) eventual USB adapters, so leaving the
CONFIG_NET_RANDOM_ETHADDR configs seems safer.

The first (already supported) has phy as subnode of gem node.

         phy0: ethernet-phy@21 {
                ...

The second has mdio subnode (with mdio name) which has phy subnode. This
structure allow hadling MDIO reset signal (based on Linux mdio.yaml)
eth {
        phy-handle = <&phy0>;
        mdio {

This patch adds support for the second case where mdio subnode
is found driver will look at its parent to find out which gem is handling
MDIO bus.

bb113ce313 xilinx: Kconfig: add XILINX_OF_BOARD_DTB_ADDR default value for microblaze
The xilinx board_fdt_blob_setup() implementation makes use of
XILINX_OF_BOARD_DTB_ADDR, but no default value is currently defined for
microblaze. Add one so that microblaze could also work with
CONFIG_OF_SEPARATE.

fc7220f0c4 microblaze: branch to base vector address on reset
Current code assumes that the vector base address is always at 0x0.
However, this value is configurable for MicroBlaze using the
CONFIG_XILINX_MICROBLAZE0_VECTOR_BASE_ADDR Kconfig option. Update the
reset routines to branch to this location instead.

f149ee4c36 microblaze: start.S: add support for configurable vector base address
Current code assumes that the vector base address is always at 0x0.
However, this value is configurable for MicroBlaze, so update the
__setup_exceptions routine to work with any vector base address.

The r4 register is reserved for the vector base address inside
__setup_exceptions and the function prologe/epilogue are also updated to
save and restore r4.

b6aef10979 microblaze: add Kconfig symbol for the vector base address
MicroBlaze vector base address is configurable (hdl C_BASE_VECTORS
configuration parameter). Current code assumes that the reset vector
location is always 0x0.

Add the XILINX_MICROBLAZE0_VECTOR_BASE_ADDR Kconfig option so the user
can adjust the reset vector address.

Migrate CONFIG_SYS_USR_EXCEP to Kconfig. Also, rename it to
XILINX_MICROBLAZE0_USR_EXCEP in order to match the naming convention of
microblaze-generic Kconfig options.

70c68712ef microblaze: drop CONFIG_SYS_RESET_ADDRESS macro
Microblaze is one the last two users of the CONFIG_SYS_RESET_ADDRESS
macro (the other is arch/powerpc/cpu/mpc8xx/cpu.c, but the macro is not
defined anywhere in powerpc code, so it should be removed there too).

Replace CONFIG_SYS_RESET_ADDRESS usage in start.S with
CONFIG_SYS_TEXT_BASE. If the reset address should really be
user-configurable, a new Kconfig option could be added.
