2a34df46b6 nand: Add a watch command
This is a debug command to monitor the retention state of the data on
the array. The command needs a duplication of the mtd_read_oob()
function to actually return the maximum number of bitflips encountered
while reading the page. We could write a specific implementation for the
Sunxi driver but this is probably enough.

    nand watch <off> <size> - check an area for bitflips
    nand watch.part <part> - check a partition for bitflips
    nand watch.chip - check the whole device for bitflips

The output may be a bit verbose and could look like:

    => nand watch.chip
    device 0 whole chip
    size adjusted to 0xff60000 (5 bad blocks)

    NAND watch for bitflips in area 0x0-0xff60000:

a527909208 malloc: Skip backtrace when stack is corrupted
When the stack is corrupted (e.g., by the stack protector test),
collecting a backtrace during malloc causes a crash because the
backtrace code walks the invalid stack frames.

Update __stack_chk_fail() to set the flag before calling panic()

Also update stackprot_test() to set the flag before intentionally
corrupting the stack. This is needed because of the printf() in the
test: on sandbox printf() results in truetype allocations due to the
console output.

These fixes allow the stack protector test to pass with mcheck enabled.

ee8e9bf104 malloc: Add malloc dump command to walk the heap
Add a new 'malloc dump' command that walks the dlmalloc heap from start
to end, printing each chunk's address, size (in hex), and status
(used/free/top). This is useful for debugging memory allocation issues.

When CONFIG_MCHECK_HEAP_PROTECTION is enabled, the caller string is
also shown if available.

Example output:
    Heap dump: 18a1d000 - 1ea1f000
         Address        Size  Status
    ----------------------------------
        18a1d000          10  (chunk header)
        18a1d010          90  used
        18adfc30          60  <free>
        18adff90     5f3f030  top
        1ea1f000              end
    ----------------------------------
    Used: c2ef0 bytes in 931 chunks
    Free: 5f3f0c0 bytes in 2 chunks + top

Expand the console-record size to handle this command.

69d2f4ab58 video: truetype: Use pre-allocated buffer for glyph rendering
The TrueType console driver calls malloc/free for every character
rendered, which causes significant memory fragmentation and allocation
traffic.

Add CONFIG_CONSOLE_TRUETYPE_GLYPH_BUF to enable a pre-allocated buffer
in the driver's private data. The buffer starts at 4KB and grows via
realloc() as needed. When rendering a glyph, use this buffer to avoid
malloc/free for normal characters.

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

Add CONFIG_VIDEO_GLYPH_STATS (default y on sandbox) to track the number
of glyphs rendered. Use 'font info' to view the count.

67ed14f985 luks: Add -p flag for pre-derived master key
Add a -p flag to the luks unlock command that allows passing a
hex-encoded pre-derived master key, skipping the KDF step. This is
useful when the master key has been derived externally, such as from a
hardware security module.

Adjust the normal flow (without -p) to use a key derived on the TKey
output. While that works OK with LUKS1, the 32-byte value is not long
enough to work with LUKS2.

Update the documentation to describe the new flag.

luks: Integrate support for a TKey
This series illustrates how to use a Tillitis TKey to unlock an
encrypted disk. This has the advantage that the key depends on a
physical key in the user's posession as well as the usual passphrase.

The TKey handles the key derivation, so this series includes logic to
skip that step when a TKey is used.

The 'luks unlock' command provides a -t flag to use a TKey.

It also provides a small pytest fix to ease conflicts with Labgrid
integration.

Cover-letter:
video: Tidy up embedded graphical images
U-Boot includes a few graphical images which are compiled in, such as
the logo and the BGRT logo used for EFI.

At present these are handled by a Makefile rule which looks for files
ending with '_logo.bmp'.

This series moves these into a new drivers/video/images directory and
puts them in a linker list, so it is possible to see what images are
available.

Adding a new image is simpler, just requiring the addition of the normal
'obj-y += file.bmp' rule.

This series also adds a new 'video' command which provides the existing
'setcurs' and 'lcdputs' as subcommands, along with documentation and
tests.

It also adds a more convenient 'write' subcommand.

817fd8201f cmd: chid: Add 'compat' subcommand to find compatible string
Add a new 'chid compat' subcommand that finds the compatible string
matching the current hardware's CHID and sets the fdtcompat environment
variable. This examines the devicetree under /chid for nodes with
hardware-id child nodes containing CHID data that matches the system's
generated CHIDs.

The command prints the found compatible string to the console and
automatically sets the fdtcompat environment variable for use by
other U-Boot commands.

Series-to: concept
Cover-letter:
Selection of devicetree using CHIDs
This series implements support for Microsoft's Computer Hardware
Identifier (CHID) specification in U-Boot. CHIDs provide a standardised
way to identify hardware configurations using SMBIOS data, enabling
automatic selection of appropriate device tree overlays and drivers when
the firmware itself lacks support for devicetree.

The CHID system generates UUIDs from various combinations of hardware
information (manufacturer, product name, BIOS version, etc.) creating a
hierarchy from most to least specific. This allows U-Boot to
automatically select the correct devicetree compatible-string for the
hardware on which it running.

This series includes:

* Core CHID Infrastructure:
   - UUID v5 generation with Microsoft's CHID namespace
   - Support for all 15 CHID variants (HardwareID-00 through HardwareID-14)
   - SMBIOS data extraction and processing

* Devicetree Integration:
   - hwids_to_dtsi.py script to convert CHID files to devicetree .dtsi
   - Automatic inclusion of the .dtsi into the board'' devicetree
   - Runtime compatible-string-selection based on hardware CHIDs

* chid command:
   - chid show - show current hardware information and generated CHIDs
   - chid list - list all supported CHID variants and generated UUIDs
   - chid variants - show information about CHID variant restrictions
   - chid compat - select the compatible string for current hardware

* ARM/EFI Support:
   - CHID mappings for a selection of ARM-based Windows devices
   - Support for Qualcomm Snapdragon platforms (MSM8998, SC7180, SC8180X,
     SC8280XP, SDM850, X1E series)

* Testing:
   - Sandbox tests using mock SMBIOS data
   - CI integration for hwids_to_dtsi validation
   - Validation against Microsoft's ComputerHardwareIds.exe output

Documentation is provided for this new subsystem and associated
commands.
