Change subject: Add functions to read/erase/write/verify by layout
......................................................................
Add functions to read/erase/write/verify by layout
Inspired by Lynxis' related work, this implements a foundation for
layout based flash access.
All operations iterate over the given layout regions. Erase and write
then walk, per region, over all erase blocks in an inner loop (which
might not be what we want, see note on optimization below). Special care
has been taken that flash content is merged properly, in case an erase
block is only partially covered by a layout region or even affects mul-
tiple regions.
A note on performance: In the case an erase block affects multiple
regions, it will probably be read, erased and written for each region.
Another approach would be to walk all erase blocks once and check for
each erase block which regions it touches (i.e. for each erase block,
merge data pontentially from the flash and all layout regions, then
flash the combined data). That might result in cleaner code. I haven't
tried it yet, though.

Change subject: Add option to read ROM layout from IFD
......................................................................
Add option to read ROM layout from IFD
Add an option --ifd to read the ROM layout from an Intel Firmware
Descriptor (IFD). Works the same as the -l option, if given, -i
specifies the images to update.
v2: o Rebased on libflashrom, use libflashrom interface.
o Use functions from ich_descriptors.c.
v3: o Move ich_descriptors.o to LIB_OBJS, thus build it independent
of arch and programmers.
o Bail out if we aren't compiled for little endian.
o Update flashrom.8.tmpl.
v4: o Incorporated David's comments.
o Removed single-character `-d` option.
