Subject: [PATCH v2 0/3] mtd: spi-nor: add Global Block Unlock support

To avoid inadvertent writes during power-up, SST26 flash memories are
write-protected by default after a power-on reset cycle. Unlock the serial
flash memory by using the Global Block Protection Unlock command - it offers
a single command cycle that unlocks the entire memory array.

v2:
- add Cyrille's reviewed-by tag
- add cover letter
- fix link to initial work done by Anurag Kumar Vulisha
