Subject: [flashrom] [PATCH 10/14] Make read_ich_descriptors_from_dump() available in flashrom
From: Nico Huber <nico.huber () secunet ! com>

I didn't really know what I was doing and hope removing the #ifdefs
doesn't have negative side effects.
The idea is to make the functions generally available for external
flashing (e.g. you might want to flash an Intel machine using an ARM
device as programmer).
Beware of big endian trouble, I guess. :-P
