Port Heads to Novacustom V560TU

[tlaurion]

• Need an upstream valid commit that can build Heads for testing.
  • Provided commit tested:
    • https://github.com/Dasharo/coreboot/tree/316f964c doesn't build, FSP paths wrong, no build recipe for EC, CBFS_SIZE needs to be increased.

[tlaurion]

Test: https://docs.dasharo.com/variants/novacustom_v560tu/releases/#v090-2024-07-18

• Dasharo commit to first try https://github.com/Dasharo/coreboot/tree/316f964c

@macpijan this commit reference config points to bad FSP paths, no recipe to build EC etc.

Please provide a commit that builds with Heads for that platform, just like #1846 iterates to a building point.

Note: meteorlake fb init for #1846 was reported having issue (GOP+coreboot fb init not working) under Heads channel around https://matrix.to/#/!pAlHOfxQNPXOgFGTmo:matrix.org/$Uu8mvr1LvKZQeIeMsmlcrrDW_HqyIbOTs1fvVeLFWaM?via=matrix.org&via=nitro.chat&via=envs.net and following threads by @mkopec

Provided hints, reviewed librem_11 GOP enabled board (used to port nv41) related PR for references:

• WiP: FB_EFI (EFIFB kernel module's framebuffer on top of libgfxinit or GOP) next steps related cleanups #1522
• librem_* (except L1UM): Linux 6.1, coreboot gfx init with efifb #1492
• a15f77e : when some tunings were discovered needed because libgfxinit does not yet support Jasper Lake.
• Initial PR switching i915 to libgfxinit's now efifb compliant FB prepared by coreboot: libgfxinit/nativegfx init: efifb enforced fb (+coreboot ramstage enabled bootsplash) #1403
  • And link to coreboot patches that were developed to permit this by @i-c-o-n (thanks again) at libgfxinit/nativegfx init: efifb enforced fb (+coreboot ramstage enabled bootsplash) #1403 (comment)

Since V560TU is also meteorlake, I guess the work done under #1846 will be useful here.

Need an upstream valid commit that can build Heads for testing.

@tlaurion here's the commit I've been using for testing: Dasharo/coreboot@db1d9cd from this branch: https://github.com/Dasharo/coreboot/commits/mtl_heads

It's just two changes that haven't been merged upstream yet, a fix for the FSP error and a commit enabling LPSS UART console for debugging.

Will ping you to cherry-pick commit of flashrom once merge upstream and then will reuse your fork with merged commits missing. Seems like a plan @mkopec ?

#1846 (comment) @mkopec

Ping me here directly with @tlaurion when coreboot commit is good including needed fixes and basic tests done for v560TU (build, EC build recipes) so I can help like it happened #1846 which now builds and boot Heads.
