Not explicitly, but it should still work fine with both versions. The old
coreboot can only either not fill up the buffer or fill u

Which works on real hardware, but
Is there an easy way for a running payload to extract additional files
from its CBFS image in ROM? I'd like to have a reproducible kernel and
initrd as the primary payload, with user data (and keys) stored in a
separate payload section of the CBFS.
On the build host I can use cbfstool to add/extr
