[PATCH 0/8] mtd: spi-nor: locking fixes and updates

[Brian Norris]

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
