Update of /home/cvs/mtd/drivers/mtd
In directory phoenix.infradead.org:/tmp/cvs-serv22136/drivers/mtd

Modified Files:
	mtdpart.c 
Log Message:
support for Protection Registers on Intel flash chips

This enables support for reading, writing and locking so called
"Protection Registers" present on some flash chips.
A subset of them are pre-programmed at the factory with a
unique set of values. The rest is user-programmable.
