[PATCH 0/2] mtd: spi-nor: add Global Block Unlock support

[<Tudor.Ambarus@xxxxxxxxxxxxx>]

From: Tudor Ambarus <tudor.ambarus@xxxxxxxxxxxxx>

This is similar with what other nor flashes are doing by clearing the
block protection bits from the status register: disable the write
protection after a power-on reset cycle.

The Global Block-Protection Unlock command offers a single command cycle
that unlocks the entire memory array. Prefer this method for higher
throughput.

Tested on the sst26vf064b flash using the atmel-quadspi driver.
