Subject: [PATCH 0/8] mtd: spi-nor: locking fixes and updates
Hi,
These are an assortment of fixes and updates to the SPI NOR lock/unlock
feature. The biggest new features are:
(a) Status Register protection; I don't see why this shouldn't be enabled by
default. See patch 4's description.
(b) Bottom-block protection support (via TB status bit)
(c) Lock/unlock support for a few Winbond flash
Patch 7 (Top/Bottom protection support) is still an RFC, as I think it deserves
a bit more work. But I'm just getting it out there, as it's been sitting on my
plate for a while.
Regards,
Brian
