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.

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.

This series collects together various small fixes and improvements which

efi: Improvements to env print -e
Printing EFI variables can be quite verbose, with many hundreds of lines

can also be hard to find a few variables visually in an unsorted list.

- Puts verbose output behind a -v flag, so that 'env print -e' behaves
more like 'env print'
- Adds a -s option to sort the list

hex dump), and -v (full verbose output).
It might be nicer to use -d to enable the dump, rather than have it on

Normally bootm proceeds sequentially through the various states, from
'start' to 'go'.
In some cases we want to load the devicetree from one FIT and the kernel
and ramdisk from another. This requires two bootm commands.
Of course it is possible to just do a second 'bootm start' to load the
kernel. But that removes all record of the devicetree from the
boot_images information, so it is then not provided to the OS.
Add a 'restart' subcommand which allows more images to be loaded,
without erasing those already loaded.
This lacks details about the subcommands, so add a description of the
boot flow and the subcommands which are available.
