image: Avoid erroneous double byte-swap in CRC value
The hash algorithm selection was streamlined in commit 92055e138f28
("image: Drop if/elseif hash selection in calculate_hash()"). Said
commit kept the call to cpu_to_uimage() to convert the CRC to big
endian format.
This would have been correct when calling crc32_wd(). However, the
->hash_func_ws member of crc32 points to crc32_wd_buf(), which already
converts the CRC to big endian. On a little endian host, doing both
conversions results in a little-endian CRC. This is incorrect.
To remedy this, simply drop the call to cpu_to_uimage(), thus only
doing the byte-order conversion once.

We are not guaranteed to have the padding_pkcs_15_verify symbol since
commit 92c960bc1d ("lib: rsa: Remove #ifdefs from rsa.h"), and
commit 61416fe9df ("Kconfig: FIT_SIGNATURE should not select RSA_VERIFY")
The padding_algos only make sense with RSA verification, which can now
be disabled in lieu of ECDSA. In fact this will lead to build failures
because of the missing symbol mentioned earlier.
To resolve this, move the padding_algos to a linker list, with
declarations moved to rsa_verify.c. This is consistent with commit 6909edb4ce ("image: rsa: Move verification algorithm to a linker list")
One could argue that the added #ifdef USE_HOSTCC is ugly, and should
be hidden within the U_BOOT_PADDING_ALGO() macro. However, this would
be inconsistent with the "cryptos" list. This logic for was not
previously explored:
Without knowledge of the U_BOOT_PADDING_ALGO() macro, its use is
similar to something being declared. However, should #ifndef
USE_HOSTCC be part of the macro, it would not be obvious that it
behaves differently on host code and target code. Having the #ifndef
outside the macro makes this obvious.
Also, the #ifdef is not always necessary. For example ecda-verify
makes use of U_BOOT_CRYPTO_ALGO() without any accompanying #ifdefs.
The fundamental issue is a lack of separation of host and target code
in rsa_verify. Therefore, the declaration of a padding algo with the
external #ifdef is more readable and consistent.

Since the beginning of this driver which was initially for the MPC8379

I couldn't find any mention in the MPC8536 that there should be a delay
of 8 clock cycles between commands. The SD card specification mentions that
the clock has to be left enabled for 8 cycles after a command or

Go ahead and just remove it. If there will ever be any regression we can

On J721e R5 SPL, dfu buffer for loading sysfw.itb image gets allocated

Also, if CONFIG_SYS_DFU_DATA_BUF_SIZE is defined and
CONFIG_SYS_DFU_MAX_FILE_SIZE is not defined then the max file size for dfu

tools: k3_fit_atf: Fix DM binary FIT load addresses
The DM binary runs on the MCU R5F Core0 after R5 SPL on J721E and J7200
SoCs. The binary is built alongside the TFA, OPTEE and A72 SPL binaries
and included in the tispl.bin FIT image. The R5 SPL loads the DM binary
at 0xA0000000 address, based on the value used in the FIT image build
script. The DM binary though is an ELF image and not a regular binary
file, and so is processed further to load the actual program segments
using the U-Boot's standard ELF loader library.
The DM binary does leverage a certain portion of DDR for its program
segments, and typically reserves 16 MB of DDR at 0xA0000000 with the
1st MB used for IPC between Linux and the remote processor, and
remaining memory for firmware segments. This can cause an incomplete
loading of the program segments if the DM binary is larger than 1 MB,
due to overlap of the initial loaded binary and the actual program
segments.
Fix this by using the address 0x89000000, which matches the current
"addr_mcur5f0_0load" env variable used by R5 SPL before the DM firmware
inclusion into the tispl.bin.

doc: Remove information about CAPSULE_FMP_HEADER
This Kconfig symbol was never added to U-Boot but it was mentioned in the
origin commit c35df7c9e43e ("qemu: arm64: Add documentation for capsule
update"). That's why remove it from documentation to be accurate.

BTRFS volume consists of a number of subvolumes which can be mounted separately
from each other. The top-level subvolume always exists even if no subvolumes
were created manually. A subvolume can be denoted as the default subvolume i.e.
the subvolume which is mounted by default.
The default "default subvolume" is the top-level one, but this is far from the
common practices used in the wild. For instance, openSUSE provides an OS
snapshot/rollback feature based on BTRFS. To achieve this, the actual OS root
filesystem is located into a separate subvolume which is "default" but not
"top-level". That means that the /boot/dtb/ directory is also located inside
this default subvolume instead of top-level one.
However, the existing btrfs u-boot driver always uses the top-level subvolume
as the filesystem root. This behaviour 1) is inconsistent with
mount /dev/sda1 /target
command, which mount the default subvolume 2) leads to the issues when
/boot/dtb cannot be found properly (see the reference).
This patch uses the default subvolume as the filesystem root to overcome
mentioned issues.

Support for register headers in v1 images was implemented in commit 02ba70ad6822 ("tools: kwbimage: Add support for DATA command also for v1
images"). So remove old comment.
