binman: Add support for flashrom FMAP
Add an entry which can hold an FMAP region as used by flashrom, an open-source flashing tool used on Linux x86 machines. This provides a simplified non-hierarchical view of the entries in the image and has a signature at the start to allow flashrom to find it in the image. Signed-off-by: Simon Glass <sjg@chromium.org>
