[coreboot] coreboot with GRUB2 for ARM Chromebook (veyron_jaq)

[John Lewis]

I don't think Grub2 is ARM compatible, so you will need to build another payload (uboot maybe)⁣. Others around here will have a better idea of how to achieve that but you should also look for documentation first to see how far you can get on your own.

Cheers,

John.
