The mccmon6 bootcmd starts with:
if test -n ${recovery_status}; then run boot_recovery; ...
The default state is "no recovery requested", i.e. recovery_status
unset. The expression then expands to 'test -n' with no operand and
relies on a U-Boot 'test' quirk that treats a missing operand as
false to skip recovery.
Quote the variable so an unset recovery_status expands to 'test -n ""'
and the emptiness check is explicit.

The Siemens am33x-common, env-common and draco-etamin headers gate
boot-partition selection logic on:
if test -n ${A}; then ...
if test -n ${B}; then ...
A and B are flags that the upgrade machinery sets to mark "the other
partition just became active". The default state is unset, in which
case the expression expands to 'test -n' with no operand and relies
on a U-Boot 'test' quirk that treats a missing operand as false to
skip the branch.
Quote each variable so an unset A or B expands to 'test -n ""' and
the emptiness check is explicit.

Rasmus Villemoes <[email protected]> says:
There are quite a few places where we allocate X+1 bytes, initialize
the first X bytes via memcpy() and then set the last byte to 0.
The kernel has a helper for that, kmemdup_nul(). Introduce a similar
one, and start making use of it in a few places. Also the existing
memdup() helper can be put to more use.
There are lots more places one could modify. But for code shared with
host tools, one would need to do some refactoring, putting memdup()
and memdup_nul() in their own str-util.c TU which could then also be
included in the tools build.

This is completely analogous to the linux kernel's kmemdup_nul()
helper, apart from the lack of the gfp_t argument: Allocate a buffer
of size {len}+1, copy {len} bytes from the given buffer, and add a
final nul byte.
This pattern exists in a number of places, so this helper can reduce
some boilerplate code.

There has never been an arch-specific optimized implementation of
str[n]dup, nor is there likely to ever be one, because unlike their
cousins strlen(), strcpy() and similar that simply read/write the
src/dst, the dup functions by definition involve memory allocation. So
drop this irrelevant cpp guard.

The helper stdio_clone only has a single caller, so it certainly
doesn't need to be public. But in fact, it is merely an open-coded
memdup() - which for some reason uses calloc() even if the whole
allocation is obviously immediately overwritten.
Drop it and just use memdup() directly.

It doesn't make sense to restrict memdup() to only return char*
pointers, especially when it is already defined to accept void*. This
makes it uglier to use to e.g. duplicate a struct.
Make it return void*, just as kmemdup() does in the kernel (and which
our kmemdup() in fact also does).
While in here, make a small optimization: memcpy() is defined to
return the destination register, so we write this in a way that the
compiler may do a tail call.

Enable automatic detection of the active A/B bank by retrieving
partition GUIDs from FWU metadata.
This ensures the system correctly identifies the bootable partitions
even in multi-bank scenarios, falling back to a standard bootable flag
scan if the UUIDs are missing.
To enable A/B bank bootup on stm32mp25 boards, add the following Kconfig
options to the stm32mp25_defconfig:
CONFIG_FWU_MULTI_BANK_UPDATE=y
CONFIG_FWU_MDATA=y
CONFIG_FWU_NUM_BANKS=2
CONFIG_FWU_NUM_IMAGES_PER_BANK=3

The Extended Boot Loader Partition (XBOOTLDR) is a standard defined by
the Discoverable Partitions Specification (DPS) to host boot loader
resources outside of the EFI System Partition ([1], [2]).
Defining this GUID (bc13c2ff-59e6-4262-a352-b275fd6f7172) allows U-Boot
to correctly identify and label these partitions using the "xbootldr"
shorthand.

The STM32MP13 default environment only handles MMC and serial/USB boot.
When TF-A reports BOOT_FLASH_SPINAND the boot_device variable is set to
'spi-nand' but bootcmd_stm32mp never redirects boot_targets to ubifs0,
so distro_bootcmd falls through to MMC/USB.
This change mirrors the STM32MP15 logic:
- Add a BOOT_TARGET_UBIFS entry to BOOT_TARGET_DEVICES so that
bootcmd_ubifs0 is defined (ubi part UBI; ubifsmount ubi0:boot).
- Add the 'spi-nand' / 'nand' clause to bootcmd_stm32mp so that
boot_targets is set to 'ubifs0' when booting from NAND.

Depending on the phase selection (single or multi), the FPWM bits
configured forces the regulator to operate in PWM mode. In case of
multi-phase selection, the FPWM_MP bits enforce the regulator to also
operate in multi-phase. This fixes correct multi-phase operation.
While at this, correct incorrect macro alignment as well.

An UMS session with eMMC device specifier "ums C mmc dev.part1,dev.part2"
exposes the same eMMC HW partition 'part2' twice instead of exposing both
HW partitions 'part1' and 'part2'. Fix this by switching the eMMC HW
partition before block device read/write access.
An eMMC is represented by a single struct blk_desc, with the currently
selected HW partition being stored in this struct blk_desc. Each call to
part_get_info_by_dev_and_name_or_num() with partition string dev[.partN]
does trigger HW partition switch by calling blk_get_device_part_str() ->
blk_get_device_part_str() -> get_dev_hwpart() -> get_dev_hwpart() ->
blk_dselect_hwpart(). The ums_init() iterates over the device specifier
string and calls part_get_info_by_dev_and_name_or_num() in a loop for
each dev[.partN] entry used as the partition string. If the device
specifier string contains more than one dev[.partN] partition strings
for the same dev device, then it is the HW partition described in the
last dev[.partN] partition string entry that is accessed for all dev
device partition strings in the device specifier string, because that
last dev[.partN] partition string entry was the last one that triggered
blk_dselect_hwpart() call for that device.
To access the expected HW partition for every dev[.partN] partition string
entry, it is necessary to call blk_dselect_hwpart() before each block read
or write. Store HW partition described for each dev[.partN] partition string
in struct ums and use the stored value to make it so.
The blk_dselect_hwpart() does test whether the currently selected HW
partition is already configured in hardware and does not reconfigure
the hardware if that is the case, therefore for the majority of block
reads and writes, blk_dselect_hwpart() is a no-op with negligible
performance impact.
Example reproducer is listed below. The last sector of both eMMC HW BOOT
partitions is populated with distinct test pattern and UMS is launched:
"
=> mmc dev 1 1 ; mmc read $loadaddr 0x1fff 1 ; md $loadaddr 4
switch to partitions #1, OK
mmc1(part 1) is current device
MMC read: dev # 1, block # 8191, count 1 ... 1 blocks read: OK
84000000: 1234abcd 1234abcd 1234abcd 1234abcd ..4...4...4...4.
=> mmc dev 1 2 ; mmc read $loadaddr 0x1fff 1 ; md $loadaddr 4
switch to partitions #2, OK
mmc1(part 2) is current device
MMC read: dev # 1, block # 8191, count 1 ... 1 blocks read: OK
84000000: 567890ef 567890ef 567890ef 567890ef ..xV..xV..xV..xV
=> ums 0 mmc 1.1,1.2
UMS: LUN 0, dev mmc 1, hwpart 1, sector 0x0, count 0x2000
UMS: LUN 1, dev mmc 1, hwpart 2, sector 0x0, count 0x2000
"
Read of the two block devices on host without this fix produces
identical data present in HW BOOT partition 2:
"
$ dd if=/dev/sdX of=mmc-a.bin ; dd if=/dev/sdY of=mmc-b.bin
$ hexdump -C mmc-a.bin | tail -n 3 | head -n 1 ; \
hexdump -C mmc-b.bin | tail -n 3 | head -n 1

This migrates the net options away from the main Kconfig to net/Kconfig,
rename the current NET option to NET_LEGACY to really highlight what it
is and hopefully encourage more people to use lwIP, add a new NET
menuconfig (but keep NO_NET as an alias to NET=n for now) which then
allows us to replace all the "if legacy_stack || lwip_stack" checks with
"if net_support" which is easier to read and maintain.
The only doubt I have is wrt SYS_RX_ETH_BUFFER which seems to be needed
for now even when no network is configured? Likely due to
include/net-common.h with PKTBUFSRX?
No change in behavior is intended. Only change in defconfig including
other defconfigs where NO_NET=y or NET is not set, in which case NO_NET
is not set or NET=y should be set in the top defconfig. Similar change
required for config fragments. See commit log in patch adding NET

I can't really decipher the log.txt, but there's no line starting with

because buildman has an exit code != 0 when it fails to build a board,
and I have the summary printed (which is the second buildman call), I
believe it means all builds passed.

As far as I could tell this data_gz is an automatically generated array

Since the move to make NET a menuconfig and NO_NET a synonym of NET=n,
when NET is enabled, NET_LEGACY || NET_LWIP is necessarily true, so
let's simplify the various checks across the codebase.
SPL_NET_LWIP doesn't exist but SPL_NET_LEGACY is an alias for SPL_NET so
the proper symbol is still defined in SPL whenever needed.

Highlight that NET really is the legacy networking stack by renaming the
option to NET_LEGACY.
This requires us to add an SPL_NET_LEGACY alias to SPL_NET as otherwise
CONFIG_IS_ENABLED(NET_LEGACY) will not work for SPL.
The "depends on !NET_LWIP" for SPL_NET clearly highlights that it is
using the legacy networking app so this seems fine to do.
This also has the benefit of removing potential confusion on NET being a
specific networking stack instead of "any" network stack.

The series include refactoring on bloblist and fdtdec to support handoff
of multiple DT overlays and applying them into the DT base during setup.
All changes are aligned to the spec update for supporting DT overlay
handoff[1].
Notes for testing:
Currently DT overlay is not yet enabled in TF-A, but with the test
patches I provided for TF-A and OP-TEE build, importing a DT overlay
blob file from QEMU to TF-A reserved memory is supported.
Follow below instructions to build and run for test:
$ repo init -u https://github.com/OP-TEE/manifest.git -m qemu_v8.xml
Replace your local qemu_v8.xml with [2], which contains all necessary
changes in both TF-A and OP-TEE build.
$ repo sync
$ cd build
$ make toolchains
$ make ARM_FIRMWARE_HANDOFF=y all
Copy and rename your DT overlay blob as 'qemu_v8.dtb' into out/bin
$ make ARM_FIRMWARE_HANDOFF=y run-only

Add an API to search for the blobs with specified tag and use the
hook function to apply the blob data.
Add a helper function to return the inline header size as according
to recent spec[1] updates, the actual data can be following an inline
header instead of following the TE header immediately.

OP-TEE message UID check API can be useful to know whether OP-TEE
is enabled on not assuming the corresponding SMC call is properly
handled if OP-TEE is not supported.
This API can be used by platform code to know OP-TEE presence and
on that basis OP-TEE DT node can be added as part of DT fixups for
the OP-TEE driver probe to happen for both U-Boot and Linux.

Add probe_ram_size_by_alias() to detect RAM size by checking whether a
write to one address aliases to another address.
Compared to get_ram_size(), this function allows the caller to:
- limit probing to a small set of required accesses
- avoid touching reserved or already used memory regions
- handle non-linear alias patterns
On the iMX95 SoC, when used with LPDDR5, accesses beyond the end of an 8GB DDR
configuration do not alias to the expected linear wrap-around addresses.
Instead, the aliased addresses appear to follow a pattern related to the
DDRC bank and bank-group addresses mapping. Experimentally, the observed
pattern is:
Write Read
y00000000 -> x0001c000
y00004000 -> x00018000
y00008000 -> x00014000
y0000c000 -> x00010000
y00010000 -> x0000c000
y00014000 -> x00008000
y00018000 -> x00004000
y0001c000 -> x00000000
This helper makes it possible to probe RAM size by explicitly specifying
the probed address and the expected alias address for each size check.

Casey Connolly <[email protected]> says:
This series implements various improvements to Linux header
compatibility, largely in preparation for a full port of Linux CCF but
many of these changes would also be helpful when porting other drivers.
Beside the basic header/compat stuff there are a few larger patches:
Patch 1 adds the "%pOF" format specifier to vsprintf, this behaves the
same as it does in Linux printing the name of the ofnode, but notably it
expects an ofnode pointer rather than a device_node.
Patch 2 adds an option to skip doing a full DM scan pre-relocation.
Some platforms like Qualcomm don't actually need devices to be probed
prior to relocation, it is also quite slow to scan the entire FDT before
caches are up. This option gets us to main loop 30-50% faster.
Unfortunately it isn't possible to totally skip DM since U-Boot will
panic if it can't find a serial port, but the serial uclass code will
bind the serial port itself by reading /chosen/stdout-path, however any
dependencies like clocks won't be found so this should only be enabled
if the serial driver gracefully handles missing clocks.
Patch 3 adds [k]strdup_const(), this works the same as the Linux version
saving a small amount of memory by avoiding duplicating strings stored
in .rodata, this is particularly useful for CCF.
Patch 4 adds 64-bit versions of some 32-bit ofnode utilities functions,
making it possible to parse 64-bit arrays.
Patch 6 provides a simple implementation of kref, this will be used
by CCF.
Patch 9 adds devm_krealloc() support to devres, it relies on storing
allocation sizes in the devres struct which will add a small overhead.
