Now I have some sort of controlled tiny fallback/normal boot,
and I went for the Cache-As-Ram with my AOpen and have new trouble:

When updating existing flash image, if my new normal/romstage is built
with ROMCC it is aligned to CONFIG_XIP_ROM_SIZE boundary (excluding some
CBFS header) and I can boot with it.

If my new normal/romstage is built with GCC for Cache-As-Ram, the same
alignment does not apply and on boot it halts before any serial output.
Everything I have should be the latest git, including the MTRR
$copy_and_run patch.

CONFIG_XIP_ROM_BASE seems obsolete? Could you take CONFIG_XIP_ROM_SIZE
from romstage CBFS-header and round that up? This is now 64kB while my
romstage takes <16kB. So this wastes precious space on flash device.
