[Nicolas Pitre]

Update of /home/cvs/mtd/include/mtd
In directory phoenix.infradead.org:/tmp/cvs-serv22416/include/mtd

Modified Files:
	mtd-abi.h 
Log Message:
user interface to Protection Registers

This is implemented using a ioctl to switch the MTD char device into
one of the different OTP "modes", at which point read/write/seek can
operate on the selected OTP area.  Also some extra ioctls to query
for size and lock protection segments or groups.  Some example user
space utilities are provided.
