Thierry Laurion	40c34453df	all scripts: replace TRACE manual strings with dynamic tracing by bash debug ... Exception: scripts sourcing/calls within etc/ash_functions continues to use old TRACE functions until we switch to bash completely getting rid of ash. This would mean getting rid of legacy boards (flash + legacy boards which do not have enough space for bash in flash boards) once and for all.

Jonathon Hall	1bf8331ffb	Blob jail: Add zstd-decompress, decompress more complex archives ... Debian 12's initrd by default now consists of an uncompressed cpio archive containing microcode, followed by a zstd-compressed cpio archive. inject_firmware.sh only supported gzip-compressed cpio, so it could not extract /init from this archive. Add zstd-decompress to decompress zstd streams (uncompressed size is about 180 KB). Add unpack_initramfs.sh which is able to decompress uncompressed, gzip, or zstd archives, with multiple segments, much like the Linux kernel itself does. Use unpack_initramfs.sh to extract /init for blob jail. Don't compress the new archive segment containing firmware and the updated /init.
