Dump the Intel Flash Descriptor map in the format expected
by flashrom's "layout" option.
Example usage:
Given a 4MB flash image vpx7654.bin that was generated by Intel's
FITC tool for a 6-Series chipset...
./ifdtool --layout l.txt vpx7654.bin
cat l.txt
00000000:00000fff fd
00180000:003fffff bios
00001000:0017ffff me
00fff000:00000fff gbe
00fff000:00000fff pd

Also, ifdtool -u /path/to/image will unlock the host's
access to the firmware descriptor and ME region.
ifdtool -l /path/to/image will lock down the host's
access to the firmware descriptor and ME region.

To avoid having two copies for every firmware descriptor (one for
EM100 use and one for real SPI flash use), add an EM100 mode to
ifdtool that allows to "dumb down" a fast image to the settings
required for the EM100 to work.
