Bring dasharo+heads MSI boards from downstream Dasharo/heads to upstream

[tlaurion]

• files: boards + coreboot + linux, borrowed directly from https://github.com/Dasharo/heads/commit/cb430394e289fcfdaace8123aed4f76148041759 tip
• cbfs-init modified as per downstream fork dasharo+heads used modifications (flashrom)
• ash_functions modified as per downstream fork dasharo+heads used modifications (CBFS)
• network-init-recovery modified as per downstream fork dasharo+heads used modifications (igc)
• modules/linux modified as per downstream fork dasharo+heads used modifications (igc)
• modules/coreboot modified as per downstream fork dasharo+heads used modifications (also impact nv41/ns50: coreboot version bump)
• modules/flashrom modified to user flashrom 1.4 + https://review.coreboot.org/c/flashrom/+/83854
• Circleci: added boards being dependent of nv41

NOTES:

• This requires Nk3 firmware to be 1.7.1+
• Requires external programmer in case of bricking, untested and not owning the platforms.
• dGPU support known problematic
• kgpe-d16 patch that was still under master was unapplied on master (permitting to flash openbmc from Heads)

DISCLAIMER: UNTESTED Sorry, not gonna cherry-pick commits from dahsharo/heads here, way too messy.

---

after merge, WILL superseed https://github.com/linuxboot/heads/pull/1489 abandonned effort.

---

TODO:

• [x] kgpe-d16 misses a working patch for internal flashing? In this PR, unapplied patch deleted. issue #1753 created

---

OLD ~DO NOT FLASH YET IF NO EXTERNAL PROGRAMMER. THIS VERSION BUMP FLASHROM SO FLASHING MASTER FROM THIS IS NEEDED~ Edit: fixed with #1755 commit cherry-picked.

WP is a huge topic, what do you need specifically?

Raw braindump. As of today, only thing used in the wild (known to be used) is for d16: ...

That's the topic that would need the aforementioned CLI update. Patches are written for flashprog, but only been rebased in the past 18 months. I'll give them a look and a little testing later.

Still working fine 😄 Added a few bits for the chips I had at hand. More testing welcome!

@i-c-o-n I see you worked on this yersterday!!!! Busy bee! Issue to be tracked would be #1546

[tlaurion]

@macpijan @SergiiDmytruk @i-c-o-n : What would be missing from flashrom today to be a direct replacement of flashrom? Please detail under #1546. Not sure flashrom deserves the energy needed to be fixed at this point, but you know way better then I do so please continue under #1546 tagging where/if needed.

We need

• current platforms supported
• WP missing, and clarifications on SPI not supporting what we need and needing resoldering, that was not clear before but now it is
• Switch to flashprog
• Be happier.

1251 resolves the issue.

@macpijan opinions?

[tlaurion]

Can be tested under #1773. Worked great on x230 and nv41

[tlaurion]

1251 resolves the issue.

@macpijan opinions?

https://github.com/linuxboot/heads/pull/1769 (flashprog) is way better fit. Would dasharo consider switching to flashprog?

[tlaurion]

Rebased on master, needs cleanup (come commits unrelevant as of now) but will wait for decision on flashrom/flashprog and letting it bitrot until then.
