Change 133128 by marcel at marcel_cluster on 2008/01/12 21:44:35

	Import cfi(4), a driver for CFI compliant flash devices.
	This supports Intel (un-tested) and AMD devices. It
	presents /dev/cfi# to userspace for reading and writing.
	
	To be done:
	o  Use KOBJ to handle the differences between the various
	   CFI implementations and commands.
	o  Add locking and unlocking of sectors.
	o  See how this can be integrated with nvram_powermac(4)
	   and likewise drivers that bundle raw CFI access with
	   high-level functionality or use of the flash device.
