Add support to get layout from fmap (e.g. coreboot rom)
Flashmap, or simply fmap, is a binary data format for describing
region offsets, sizes, and certain attributes and is widely used by
coreboot. This patch adds support for the fmap data format version 1.1
and adds --fmap and --fmap-file arguments.
Using --fmap will make flashrom to search the ROM content for fmap
data. Using --fmap-file will make flashrom search a supplied file
for fmap data.
An example of how to update the COREBOOT region of a ROM:
flashrom -p programmer --fmap -w coreboot.rom -i COREBOOT
flashrom -p programmer --fmap-file coreboot.rom -w coreboot.rom -i COREBOOT
The fmap functions are mostly copied from cbfstool.
Currently it is made mutually exclusive with other layout options until
we are more clever about this input.
