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.
