In order to support verstage the cache-as-ram split
is taken advantage of such that verstage has the
cache-as-ram setup and rosmtage has the cache-as-ram
tear down path. The verstage proper just initializes
the console and attempts to run romstage which triggers
the vboot verification of the firmware. In order to
pass the current FSP to use during romstage a global
variable in cache-as-ram is populated before returning
to the assembly code which tears down cache-as-ram.
BUG=chrome-os-partner:44827
BRANCH=None
TEST=Built and booted glados with verstage support as well as
VBOOT_DYNAMIC_WORK_BUFFER with direct link in romstage.
