pcr: libreboot-utils: Add ifdtool
Recent (post 2006) Intel computers typically have a flash chip that
contains several partitions:
- An "Intel flash descriptor" partition that contains a partition
table, permission settings for read/write access to these
partitions. various configuration settings like the flash chip
speed, and so on.
- A partition for the BIOS that contains the BIOS, Coreboot, EFI,
Libreboot, UEFI, etc.
- A partition for the Management Engine firmware.
- A partition for some Gigabit Ethernet settings (the MAC address,
LEDs settings, etc).
- A partition named "Platform data" that probably contains some serial
numbers or other data on some computers.
The ifdtool utility can display these partitions, various settings
present in Intel flash descriptor, extract or replace these partitions
content, etc.
