Resolve conflicts, enable TPM2 support into board configs that was missing sorry - remove blobs/kabylake/fetch_split_fsp.sh since unneeded if depending on full FSP from tree - removed fsp.fd files placed in blobs and references to it in @gaspar-ilom branch - removed blobs/kabylake/* altogether since unneeded - remove patches/coreboot-24.02.01/* since we use another fork (currently modules/coreboot: t480, might be renamed to coreboot release to be reused later) - t480 boards depend on targets/xx80_me_blobs.mk now, next commit will cleanup prior work artifacts not needed; @gaspar-ilom approach cleaner Signed-off-by: Thierry Laurion <insurgo@riseup.net>
The ME blobs dumped in this directory come from the following link: https://dl.dell.com/FOLDER04573471M/1/Inspiron_5468_1.3.0.exe
This provides ME version 11.6.0.1126. In this version CVE-2017-5705 has not yet been fixed.
See https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00086.html
Therefore, Bootguard can be disabled by deguard with a patched ME.

1.0.1: Extract blobs from original rom:
extract.sh: takes backup, unlocks ifd, apply me_cleaner to neuter, relocate, trim and deguard it, modify BIOS and ME region of IFD and place output files into this dir.
sha256sum: will vary depending of IFD and ME extracted where IFD regions of BIOS and ME should be consistent.
1.1: More blobs

ifd.bin was extracted from a T480 from an external flashrom backup.
