081b97c3b3 spl: Kconfig: ARCH_K3: Set default SPL_STACK_R_MALLOC_SIMPLE_LEN for R5 build
All ARCH_K3 platforms need about of 2MB of malloc space post
reallocation. Since, this space is allocated from SDRAM, provide a
generous 2MB space by default.

Platforms requiring more than 2MB can override in defconfig as needed.

939f17c8a9 arm: dts: k3-j721s2-r5: Change GTC clock parent
MAIN_PLL0 has a flag set in DM (Device Manager) that removes its
capability to re-initialise clock frequencies. A72 CPU clock (GTC) and
RGMII has MAIN_PLL3 as their parent which does not have this flag. While
RGMII needs re-initialization to default frequency to be able to get
250MHz with its divider, GTC can not get its required 200MHz with its
dividers. Thus move GTC clock parent on J721S2 from MAIN_PLL3_HSDIV1 to
MAIN_PLL0_HSDIV6. This was already done on CPTS node in kernel which was
similarly affected (linked).

ca6a992e09 cmd: sound: fix help text
There's never been a -q or -s argument handled in the command, so let's
remove it. This was highlighted during review[1] but somehow still got
through.

While at it, slightly "reword" in the help text how the len + freq
arguments are defined. Indeed, len and freq work in pair, it is possible
to define none of either, n of both, or n - 1 of freq if there are n
len, in which case the freq that goes with the last len would be the n -
1 (and not the default of 400Hz if neither len nor freq is passed). I
assume this isn't what's expected but leaving it for another patch if
need be to fix what happens in that very odd scenario.

3b7d26eb2b efi_loader: Fix EFI_VARIABLE_APPEND_WRITE hash check
According to UEFI v2.10 spec section 8.2.6, if a caller invokes the
SetVariables() service, it will produce a digest from hash(VariableName,
VendorGuid, Attributes, TimeStamp, DataNew_variable_content), then the
firmware that implements the SetVariable() service will compare the
digest with the result of applying the signer’s public key to the
signature. For EFI variable append write, efitools sign-efi-sig-list has
an option "-a" to add EFI_VARIABLE_APPEND_WRITE attr, and u-boot will
drop this attribute in efi_set_variable_int(). So if a caller uses
"sign-efi-sig-list -a" to create the authenticated variable, this append
write will fail in the u-boot due to "hash check failed".

This patch resumes writing the EFI_VARIABLE_APPEND_WRITE attr to ensure
that the hash check is correct. And also update the "test_efi_secboot"
test case to compliance with the change.

c1eb7a993d arm: move _end to linker symbols
commit 6e2228fb05 ("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 d0b5d9da5d ("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.

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.

Introduce fdt_apply_ddrss_timings_patch() to allow board code to
override DDR settings in the device tree prior to DDRSS driver probing.

e63908adbd arm: mach-k3: am625: Call do_board_detect() before DDR probing
Call do_board_detect() hook before the K3 DDRSS driver gets probed.
It will allow boards to adjust DDR timings in do_board_detect().

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.

Enable CONFIG_ENV_OVERWRITE to overwrite ethaddr in the environment.
This is required because our environment is not located in the
boot partition.

b100c2458a board: phytec: common: Add API v3
This API is based on a block structure with a 8 Byte large
API v3 header and various of different blocks following. It extends
our current API v2, which is always 32 Byte large, and is located
directly after v2.

Add the MAC block as first block type. It contains the physical
Ehternet interface number, a MAC address and a CRC checksum over the
MAC payload.
