   4 Subject: [PATCH 1/2] mtd: spi-nor: add block protection flags to macronix
   5
   6 Macronix flash chips support block protection by using BP bits in the
   7 read status register. Add the corresponding flag to indicate block
   8 protection support.
   9
  10 Otherwise, locked blocks are not unlocked when requested.
