On systems that do not provide their own *.fmd (Flashmap) file, we
fall back to a default flashmap file. That file however does not contain
the blobs (ME, GBE ...), that are usually placed below the BIOS Flashmap.
It can therefore easily happen that the placement of the blobs collides
with the placement of the BIOS region (e.g. if CBFS_SIZE is big enough).
The fmaptool can't catch that, since it does not know of the blobs
placement.
This patch basically maps the regions described in the IFD (Intel
Firmware Descriptor) to the default Flashmap.
Test: Build and see that build/fmap.fmd contains all blobs now (on intel
systems that are supported by the ifdtool)

correct formula since commit 8d2bfbce23 ("soc/amd/sabrina/acpi:
Correct VID decoding on Sabrina"), but the MSR definition in the PPR
hasn't been updated to show the additional bit. The definition of the

Implement initial support for EMI (Embedded Memory Interface), which
Microchip describes as "a standard run-time mechanism for the system
host to communicate with the Embedded Controller (EC) and other logical
components". EMI allows the host to access regions of EC memory without
requiring any assistance from the EC.
For now, Atlas only uses EMI 0. This change enables EMI 0, subsequent
commits will read data from it.
