From: Nitin A Kamble <nitin.a.kamble at intel.com>

This recipe provides the microcode datafile for Intel Processors.

The recipe provides:
 1. microcode.dat file for microcode updating from user space with the
    iucode-tool utility.
 2. the microcode cpio file which gets bundled with the initrd to support
    microcode loading at early boot time.

Note that this recipe has LICENSE_FLAGS so will need to be whitelisted before
it's usable.

+DESCRIPTION = "The microcode data file contains the latest microcode\
+ definitions for all Intel processors. Intel releases microcode updates\
+ to correct processor behavior as documented in the respective processor\
+ specification updates. While the regular approach to getting this microcode\
+ update is via a BIOS upgrade, Intel realizes that this can be an\
+ administrative hassle. The Linux operating system and VMware ESX\
+ products have a mechanism to update the microcode after booting.\
+ For example, this file will be used by the operating system mechanism\
+ if the file is placed in the /etc/firmware directory of the Linux system."
