If you have a fix for inclusion to newconfig, we'll be happy to merge
it, of course!

CBFS is not incompatible to failover (or vice versa). It might not work,
but that would be a bug to fix.

The Kconfig effort (which is separate from CBFS) does not implement
failover, or any fallback/rescue mechanism at all at this time.

After finishing CAR? That would be very early.
There are a couple of places (loading coreboot_ram and loading the
payload) that can take a considerable amount of time (several minutes in
some cases) on certain AMD boards. Maybe the board is simply very busy
with copying the next stage?
Of course this must be fixed, but first we'll have to know what to fix.

Please post a log :-)
