[PATCH 2/2] [MTD] mtd-utils: Use new 64-bit ioctls to access >4GiB devices (take 2)
Kevin Cernekee
kpc.mtd at gmail.com
Fri Mar 20 01:37:42 EDT 2009
Use the new kernel ioctls to support >4GiB flash devices. Falls back to
the old ioctls if the kernel does not have the new ABI.
Sanity tested using 8MB nandsim:
flash_eraseall
flash_erase
flashcp
mtd_debug
nanddump
nandwrite
Untested:
flash_lock
flash_unlock
