First, try and be slightly clearer about what "buildx" is with respect
to the docker build process.
Second, now that we build the container for both amd64 and arm64, we
should document how to make a docker "builder" that has multiple nodes.
With this one node should be amd64 and one node arm64, and with
reasonably fast arm64 hardware this will be much quicker than using
QEMU.

Rather than doing autoprobe within the driver model code, move it out to
the board-init code. This makes it clear that it is a separate step from
binding devices.
For now this is always done twice, before and after relocation, but we
should discuss whether it might be possible to drop the post-relocation
probe.
For boards with SPL, the autoprobe is still done there as well.
Note that with this change, autoprobe happens after the
EVT_DM_POST_INIT_R/F events are sent, rather than before.

Add a description of how test parameters work. This helps to make it
easier to write C tests which need setup to be done in Python.

Cover-letter:
test: Add support for passing arguments to C unit tests
This series adds infrastructure for passing runtime arguments from Python
tests to C unit tests. This makes it easier to support a hybrid testing
approach where Python handles complex setup (filesystem images,
environment configuration) while C handles the actual test logic with
better debuggability.
A few other things are included to make this work:
- A fix for linker list alignment that was causing garbage values like
"Running -858993444 bloblist tests" due to GCC's magic-number division
optimization failing when padding breaks exact multiples
- A fix fix for serial output with sandbox, since it sometimes misses
output at the end when running tests with gnome terminal
- Improvements to the linker-list script to detect padding and
pointer-arithmetic bugs
- A new UNIT_TEST_ARGS() macro for declaring tests with typed arguments,
along with argument parsing in the ut command (name=value format)
- Argument-accessor macros ut_str(), ut_int(), and ut_bool() with
type-checking and bounds validation
- A private buffer (uts->priv) for test-local temporary data, which
makes it a little easier to write shorter tests
- Tests for the argument feature (test_args) covering type checking,
bounds checking, and argument-parsing failures
As an example, the basic filesystem tests are converted from pure Python
to C with Python wrappers.
Some improved printf documentation and support for Linux's %pV format
are provided.
The slight increase in size causes qemu-riscv64_spl to fail, so this
series also includes a patch to increase the SPL-malloc() space.

Update the malloc() with more info about the debugging features:
- CONFIG_MALLOC_DEBUG and CONFIG_MCHECK_HEAP_PROTECTION Kconfig options
- The malloc command with info and dump subcommands
- Caller backtrace display when mcheck is enabled

Cover-letter:
malloc: Add heap debugging commands and mcheck caller tracking
This series adds improved heap-debugging capabilities.
As part of this, the recently added backtrace feature is reworked to
avoid itself using malloc(), which makes it difficult for malloc() to
use.
A new 'malloc' command with 'info' and 'dump' subcommands allows
inspecting the heap state at runtime.
The mcheck heap-protection feature is integrated into Kconfig and can be
used to to track caller information for each allocation, showing the
function name and line number.
The caller info can be seen with 'malloc dump', including for freed
chunks where possible.
The 'malloc info' command shows a few more heap statistics:
=> malloc info
total bytes = 96 MiB
in use bytes = 700.9 KiB
malloc count = 1234
free count = 567
realloc count = 89
The 'malloc dump' command walks the heap showing each chunk:
=> malloc dump
Heap dump: 19a0e000 - 1fa10000
Address Size Status
----------------------------------
19a0e000 10 (chunk header)
19a0e010 a0 log_init:453 <-board_init_r:774 <-sandbox_flow:

...
19a4b080 70 free done_word:2489 <-parse_stream_outer:3190 <-pars
...
This is useful for debugging memory leaks, understanding allocation
patterns, and tracking down heap corruption issues.
Some additional patches are included to make all this work:
- format_size() for human-readable size formatting
- ut_asserteq_regex() for flexible test assertions
- backtrace_str() for condensed backtrace output
Finally, this series includes a few patches for some of the more obvious
memory leaks (scmi and some test drivers), plus a reduction in truetype
memory allocations and a fix for a watchdog crash with 'ut dm'.

When CONFIG_MCHECK_HEAP_PROTECTION is enabled, use backtrace_str() to
capture the caller information for each malloc/calloc/realloc/memalign
call. This information is stored in the mcheck header and can be viewed
with 'malloc dump'.
Add a flag to disable the backtrace when the stack is corrupted, since
the backtrace code tries to walks the invalid stack frames and will
crash.
Note: A few allocations made during libbacktrace initialisation may
not have caller info since they occur during the first backtrace call.
Example output showing caller info:
18a1d010 90 used log_init:453 <-board_init_r:774
18a1d0a0 6060 used membuf_new:420 <-console_record

in the driver's private data. The buffer starts at 4KB and grows via

The buffer is allocated lazily after relocation to avoid consuming
early malloc space before the full heap is available.

of glyphs rendered. Use 'font info' to view the count.

malloc: Import dlmalloc 2.8.6
This series imports dlmalloc 2.8.6 from Doug Lea, replacing the old
version 2.6.6 that U-Boot has been using since 2002.
The new version provides:
- Better memory efficiency with improved binning algorithms
- More robust overflow checking via MAX_REQUEST
- Somewhat cleaner codebase
All U-Boot-specific modifications from the historical commits have been
ported to the new implementation, including:
- Pre-relocation malloc via malloc_simple
- Valgrind annotations
- Malloc testing infrastructure
- mcheck heap protection support
- Sandbox USE_DL_PREFIX support
The approach here is to leave the upstream code unchanged, so much as
possible, clearly marking U-Boot-specific changes with an #ifdef
Unfortunately the code size is not great out-of-the-box, so the final
part of the series includes some options to remove in-place realloc(),
provide a simplified init, remove the tree stucture for large blocks
and a few other things.
With these adjustments the new version is about 1K less code on Thumb2
(firefly-rk3288).
The new free() algorithm is more sophisticated but also larger. If
needed we might be able to shrink by a few hundred bytes. Of course SPL
doesn't normally use free() so the benefit might be minimal.
Another point worth mentioning is that the pre-inited av_[] array has
been replaced replaced with a BSS _sm_ struct which reduces the image
size by about 1.5K. One patch adjusts some imx8mp boards to deal with
the larger BSS.
Some code-size stats:

For the new malloc.h I have avoided including string.h so have added
that to various places that need it.
The existing common/dlmalloc.src file is left alone.
In order to bring this in without losing functionality, I went through

these commits were added, they are added as a cherry-pick, with the
original commit hash.

Display relative paths instead of absolute paths in backtrace output,
making the output cleaner and more portable across different build
environments.
This works by adding a SRCTREE define to lib/backtrace.c and stripping
it from filenames when printing.
Series-to: concept
Series-cc: heinrich
Cover-letter:
backtrace: Add runtime support for looking at the backtrace
In some cases the backtrace contains useful information, such as whether
a particular function was called earlier in the stack.
This series provides a very simple backtrace library, along with some
sandbox-specific functions to allow it to work. It is designed such that
another arch could implement it.
A new 'backtrace' command provides access to the backtrace.
