+ Sandy Bridge can either start verstage in a separate stage
+ right after the bootblock has run or it can start it
+ after romstage for compatibility reasons.
+ Sandy Bridge however uses a mrc.bin to initialize 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.
