Subject: Add support for romfs to option rom loading.
X-Git-Url: http://wien.tomnetworks.com/gitweb/?a=commitdiff_plain;h=662d52d24426b8fb8d11d455f8b30ae67a669ade;p=coreboot.git

Add support for romfs to option rom loading.

Pretty simple: Find the rom in the romfs, if found, set dev properties so
that the rest of the code works.

At some point, we can remove some of the other code, i.e. the first else,
and stop requiring people to do math.
