Subject: [PATCH 1/2] mtd: spi-nor: add block protection flags to macronix
|
||
|
|
|
||
|
|
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.
