grub2 payload: not including additional modules

[Arian Sanusi]

Hi all,

I try to build coreboot-4.4 with grub2 payload for a thinkpad T420. Which largely works, but I'm unable to get it to build coreboot.rom with extra grub modules, in particular cryptodisk.mod

relevant .config:
> arian@jira:coreboot-4.4$ grep GRUB .config
> CONFIG_PAYLOAD_GRUB2=y
> CONFIG_PAYLOAD_FILE="payloads/external/GRUB2/grub2/build/default_payload.elf"
> CONFIG_GRUB2_MASTER=y
> CONFIG_GRUB2_EXTRA_MODULES="luks cryptodisk crypto pbkdf2 extcmd procfs archelp"

(I put in the additional modules since I thought it's maybe dependency resolution, but of these crypt, pbkdf2, procfs and archelp make their way into the image, while luks, cryptodisk, and extcmd don't. There is no error.

I think this is a coreboot problem since the modules themselves are getting built, I can find them in payloads/external/GRUB2/grub2/build/grub-core/cryptodisk.mod

Could anyone help?

Thanks and best regards,

Arian
