help
Broadwell can either start verstage in a separate stage
right after the bootblock has run or it can start it
after romstage for compatibility reasons.
Broadwell however uses a mrc.bin to initialse memory which
needs to be located at a fixed offset. Therefore even with
a separate verstage starting after the bootblock that same
binary is used meaning a jump is made from RW to the RO region
and back to the RW region after the binary is done.
