ARM bootblock approach
This lays out the groundwork for using a proper bootblock on ARM.
Currently we bypass the bootblock entirely and go straight to
romstage. However we want to utilize CBFS to maximize flexibility
of placing code without relying on a lot of magic numbers which
will break depending on the SoC in use.
