64437a05d2 qemu: arm: Remove platform specific function to get RNG device
The QEMU platform has a function defined to get the random number
generator(RNG) device. However, the RNG device can be obtained simply
by searching for a device belonging to the RNG uclass. Remove the
superfluous platform function defined for the QEMU platform for
getting the RNG device.

52ae8d6cc8 board: gateworks: venice: determine dram size at runtime
The SPL does not update the memory node with the dram size from EEPROM

to determine the available RAM. Update PHYS_SDRAM_SIZE to 4GiB as that

dd2986ac11 powerpc: Fix incorrect SYS_IMMR migration values
When migrating SYS_IMMR, I didn't allow for boards to provide
non-default values here.  This lead to an incorrect migration on the
platforms where CONFIG_SYS_IMMR is set to CONFIG_SYS_CCSRBAR and
CONFIG_SYS_CSSRBAR is NOT the same as CONFIG_SYS_CCSRBAR_DEFAULT.  Add
text to the prompt so that non-default values can be used and re-migrate
the platforms that have CONFIG_SYS_IMMR=CONFIG_SYS_CSSRBAR where
CONFIG_SYS_CSSRBAR != CONFIG_SYS_CCSRBAR_DEFAULT.

408e2d5a22 boot: image: fixup zstd decompression buffer initialization typo
The code was mistakenly initializing the input buffer twice.

Tested to be working on BeagleBone by adjusting CONFIG_SYS_BOOTM_LEN to
64MiB (probably works with less) and preparing uImage with:

 cat arch/arm/boot/Image \
  | zstd --ultra -22 --zstd=windowLog=22 \
  > linux.bin.zst

 mkimage -A arm -T kernel uImage -C zstd -d linux.bin.zst \
  -a 0x80008000 -e 0x80008000

Without the windowLog restriction, bootm fails with a zstd decompression
error 7 (window too large), which I haven't troubleshooted.

There should be a bit more documentation on the feature...

85da558762 sunxi: dts: Update RGMII phy-mode properties
Commit f11513d997 ("net: phy: realtek: Add tx/rx delay config for
8211e") made the Realtek PHY driver honour the phy-mode DT property,
to set up the proper delay scheme for the RX and TX lines. A similar
change in the kernel revealed that those properties were mostly wrong.
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.

This fixes Ethernet operation on the affected boards.

e943753dc2 sunxi: Fix old GMAC pinmux setup
Commit 5bc4cd05d7 ("sunxi: move non-essential code out of s_init()")
moved the call to eth_init_board() from s_init() into board_init_f().
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.

This fixes Ethernet operation for the A20 SoCs, which broke in
v2022.04-rc1, with the above mentioned commit.

Pali Rohár
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.

532a5b297c misc: atsha204a: fix i2c address readout from DTS
This patch replaces use fdtdec_get_addr with simpler dev_read_addr().
fdtdec_get_addr doesn't work properly on ZynqMP-based (64bit) system. Although
not confirmed, it could be related to the fact, that quoting the documentation,
"This variant hard-codes the number of cells used to represent the address and
size based on sizeof(fdt_addr_t) and sizeof(fdt_size_t)".

9c045a49a9 efi_loader: move dtbdump.c, initrddump.c to lib/efi_loader
The tools dtbdump.efi and initrddump.efi are useful for Python testing even
if CONFIG_EFI_SELFTEST=n.

Don't clear the screen as it is incompatible with Python testing.

b78631d54f efi_loader: remove efi_disk_is_system_part()
The block IO protocol may be installed on any handle. We should make
no assumption about the structure the handle points to.

efi_disk_is_system_part() makes an illegal widening cast from a handle
to a struct efi_disk_obj. Remove the function.

63276a569d efi_loader: use short-form DP for load options
The GUID of partitions is sufficient for identification and will stay
constant in the lifetime of a boot option. The preceding path of the
device-path may change due to changes in the enumeration of devices.
Therefore it is preferable to use the short-form of device-paths in load
options. Adjust the 'efidebug boot add' command accordingly.
