Looking at cbmem -c output this seems to be where the 5 seconds is
being lost, but it's truncating the output. How can I stop cbmem from
truncating the output so I can see what's going on?

After some toing and froing with Aaron Durbin over the last 6 hours
this is where we are:
mrc.cache is now working but cold boot still takes roughly 5 seconds
to
get to SeaBIOS display. Warm boot/reset is instantaneous. Aaron says
the
mrc.bin blob is not happy (and we can't have an unhappy blob now, can
we).
In order to get mrc.cache working this is what's required:
1. Remove 'select CHROMEOS' from src/mainboard/samsung/lumpy/Kconfig.
2. Add this patch:
diff --git a/src/vendorcode/google/chromeos/gnvs.h
b/src/vendorcode/google/chrom

3. make oldconfig
4. make clean
5. make (obviously)
Additionally, to get timing information in cbmem -c and cbmem -t the
following was necessary:
1. Add 'select LAPIC_MONOTONIC_TIMER' to
src/mainboard/samsung/lumpy/Kconfig
2. make oldconfig
3. make (again obviously)
The cbmem output is attached. Where to go from here? Many thanks to
Aaron for all his help.
