d9f7f42451 cmd: efidebug: add support for setting fdt
We already support creating a load option where the device-path
field contains the concatenation of the binary device-path and
optionally the device path of the initrd which we expose via the
EFI_LOAD_FILE2_PROTOCOL.

Allow to append another device-path pointing to the device-tree
identified by the device-tree GUID.

f9886bc60f Added arm64 assembly for examples/api crt0
I've encountered a problem when compiling the 'examples/api' directory for ARM64 in U-boot. The problem lies in the assembly code in 'examples/api/crt0.S' where the current CONFIG_ARM code is only 32-bit. When targeting ARM64, a 64-bit version is necessary.

I have proposed a fix by including a 'CONFIG_ARM64' section in the assembly code as shown below.  These changes have been check via https://github.com/u-boot/u-boot/pull/538.

Feedback is welcome.

17b1656dcd abootimg: Add init_boot image support
Quote from [1]:

"For devices launching with Android 13, the generic ramdisk is removed
from the boot image and placed in a separate init_boot image.
This change leaves the boot image with only the GKI kernel."

While at it, update wrong error handling message when vendor_boot
cannot be loaded.

c1eb7a993d arm: move _end to linker symbols
commit 6e2228fb052b ("Merge patch series "Clean up arm linker scripts")
was cleaning up linker scripts for armv7 and v8 but was leaving
_end and __secure_stack_start/end.

commit d0b5d9da5de2 ("arm: make _end compiler-generated")
was moving _end to be compiler generated. _end is defined as c variable
in its own section to force the compiler emit relative a reference.
However, defining those in the linker script will do the same thing
since [0].

So let's remove the special sections from the linker scripts, the
variable definitions from sections.c and define them as a symbols.
It's worth noting that _image_binary_end symbol is now redundant and
can be removed in the future.

- SPL

The .end section has been removed from the new binary

3078766134 image: Set load_end on partial loads
When decompressing, it's possible that the algorithm only performs
a partial decompression.
This usually happens when CONFIG_SYS_BOOTM_LEN is too small for
the uncompressed image.

When that happens, image_decomp() returns an error and *load_end == load.
The error is then handled by handle_decomp_error().

handle_decomp_error() expects the number of uncompressed bytes in
uncomp_size but receives *load_end - load == load - load == 0.

Because of this, handle_decomp_error does not report the expected
"Image too large: increase CONFIG_SYS_BOOTM_LEN" error message.

Modify the image_decomp() logic to always report the decompressed size,
even when a partial decompression happened.

9fa98591d7 Merge patch series "PHYTEC SOM Detection API v3"
Daniel Schultz <d.schultz@phytec.de> says:

This patch series adds support for the EEPROM v3 API.

V3 is backwards compatible to V2 and therefore, the V2 image still
exists at the beginning. Only the API version changed from 2 to 3.

V3 is a block-based memory layout organized as singled-linked list
with different types of blocks. This is a more flexible approach and
allows us to extend it by more block types in the future.

The V3 data starts with a 8-byte large header which defines the
block count (u8), V3 subversion (u8) and data payload length (u16).
Additionally the header contains a CRC8 checksum a 3 reserved bytes.

Each block starts with a 4-byte large header which defined the
block type (u8), the absolute address of the next block (u16) and a
CRC8 checksum. The content itself is defined via the block type and
we currently have 2 different types:

1) MAC: Contains the Ethernet interface number (u8), MAC address
        (6 x u8) and a CRC8 checksum.

3bdc128565 arm: dts: k3-am625-verdin: Update autogenerated LPDDR4 configuration
Update the autogenerated LPDDR4 configuration using the latest available
SysConfig tool.
This changes are cosmetic and are made to track the last used tool version.

77ba281c91 Merge patch series "'eeprom' command improvements"
Marek Behún <kabel@kernel.org> says:

This series contains improvements for the 'eeprom' command:
- refactors
- fixes
- improvements
- ability to use driver model EEPROMs (uclass UCLASS_I2C_EEPROM)
- more flexible EEPROM layout support

It should not cause any behavior change for any existing board.

This series is a dependency for some DDR issue fixes for Turris Omnia.
I will be sending that one separately.

github PR link (with CI):
  https://github.com/u-boot/u-boot/pull/540
- there is a failure for
    test.py for sandbox sandbox_clang
  but it seems unrelated to these changes

57a9e8d86f cmd: eeprom: Extend to EEPROMs probed via driver model
Extend the 'eeprom' command to allow accessing EEPROMs probed via
driver model, uclass UCLASS_I2C_EEPROM.

When the CONFIG_I2C_EEPROM config option is enabled (and so the
i2c-eeprom driver is built), the 'eeprom' command now accepts driver
model device name as EEPROM specifier for the 'eeprom' command, in
addition to the legacy [[bus] devaddr] specifier.

Moreover if no device specifier is given, then the first
UCLASS_I2C_EEPROM device is used, if found.

15f0536f29 cmd: eeprom: Refactor eeprom device specifier parsing
In preparation for allowing to access eeprom by driver-model device
name, refactor the eeprom device specifier parsing. Instead of filling
two parameters (i2c_bus, i2c_addr), the parsing function now fills one
parameter of type struct eeprom_dev_spec.

2d49dafe4a cmd: eeprom: Hide eeprom layout versioning behind a Kconfig option
Add a new Kconfig option EEPROM_LAYOUT_VERSIONS, and hide eeprom
layout versionsing code behind it. Only print the relevant help in
'eeprom' command usage if this option is enabled.

Enable this new option for cm_fx6_defconfig and cm_t43_defconfig.
These are the only boards using EEPROM layout versioning.

The byte variable is of type unsigned char, it is never less than zero.
The error case is handled by *endptr, so drop the comparison altogether.
