[MTD] Support for protection register support 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. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
