PoC : D16 - Bump kernel 6.1.8 + coreboot to fam15h (justmike80386) branch

[tlaurion]

WARNING: No measured boot is occurring until patches 0001, 0020 and 0021 are ported over

---

Based on #1803 + switching to fam15h's coreboot fork (without patches/coreboot-4.11 patches)

Discussion leading to this PR around https://matrix.to/#/!OkpUfvLEYpLyALVvaW:dodoid.com/$4ydLUMFeRvt9eQLOK_Us3v8yFC9JekLAGG0ly5w02_I?via=dodoid.com&via=matrix.org&via=envs.net (for those already part of d16 club -> fam15h matrix room)

(Github slow at receiving CircleCI API calls once builds lauched prior of PR created)

With patches 0001, 0020 and 0021 copied over (not ported from patches/coreboot-4.11)

Local logs (CircleCI will provide same for that branch containing those patches, not here):

Patches welcome.

Ideally:

• Patches from dasharo (bootblock instead of romstage measured boot) would replace the patches/coreboot-4.11 patches currently missing)

Other branch with 4.11 measured boot in romstage patches in at https://app.circleci.com/pipelines/github/tlaurion/heads/2882/workflows/b16fb6a4-5aa8-4dc5-a8f3-87f8031b815c, will fail and logs will be observable there for those interested in moving things forward.

As said in OP: the desirable patches are not those from tlaurion@9b8257c but backporting Dasharo ~4.15 (commit based between 4.14-4.15 from their branch) patches to 4.11 so measured boot is in bootblock.

Please comment here and/or provide needed patches.

Thank you.
