Even if sst26vf shares the SPINOR_OP_GBULK opcode with Macronix (ex. MX25U12835F) and Winbound (ex. W25Q128FV), it has its own Individual Block Protection scheme, which is also capable to read-lock individual parameter blocks. Thus the sst26vf's Individual Block Protection scheme will reside in the sst.c manufacturer driver. Add support to unlock the entire flash memory. The device is write-protected by default after a power-on reset cycle (volatile software protection), in order to avoid inadvertent writes during power-up. Could do an erase, write, read back, and compare when MTD_SPI_NOR_SWP_DISABLE_ON_VOLATILE=y.
