PS1:
> I mean, we can start building coreboot from the firmware-android branch as well if you think this is important enough.

yes, we are working on a specific fw branch to build fatcat.
> Or you can put a line to set this after building in some script, or in an ebuild guarded by a USE flag or something. It does not belong here. (Besides, your patch sets it to `default n` anyway so on its own this patch does nothing?)

that is correct but for CPFE builders to work, we need to make sure that we are checking that code as well (i.e., the code that edits the GBB bit 31) and this code just meant to do the same. I'm unable to find any other fatcat SoC/MB specific ebuild that would be applicable to set GBB bit 31 for ADB alone.
