None of this is useful to us since we get most of this information
from skiboot, but I'm not sure that's true for other platforms. The
kernel boot log is fairly noisy as-is so we don't gain much from
trimming. At the very least the other messages provide sanity checks
that we've exited firmware and/or the bootloader without issues. I'll
look at changing the returned error messages though, "invalid block
type" is a pretty error useless you already know what you're looking
for.

Right also if you crash in the kernel itself and these are your last
messages, knowing where the kernel was expanded can be useful.
