Subject: [PATCH 1/2] mtd: spi-nor: add block protection flags to macronix
Date: Wed,  3 Mar 2021 10:48:32 +0100	[thread overview]
Message-ID: <20210303094833.139221-1-mail@david-bauer.net> (raw)

Macronix flash chips support block protection by using BP bits in the
read status register. Add the corresponding flag to indicate block
protection support.

Otherwise, locked blocks are not unlocked when requested.
