Many SPI NOR flash devices support status register protection through
one or two status register protection bits. Protection of the status
register is essential in defending the device from rogue software which
may attempt to modify block protection bits in order to make malicious
modifications to the data stored in flash. This patch series adds
status register protect support for STMICRO, SST, Winbond and Spansion
devices and also implements an sf sub-command to set the used
protection method.
