Raw NAND chip driver changes:
* Toshiba:

* Macronix:
  - Add support for deep power down mode
  - Add support for block protection

SPI-NAND core changes:
* Do not erase the block before writing a bad block marker
* Explicitly use MTD_OPS_RAW to write the bad block marker to OOB
* Stop using spinand->oobbuf for buffering bad block markers
* Rework detect procedure for different READ_ID operation

SPI-NAND driver changes:
* Toshiba:

SPI NOR core changes:
* Move all the manufacturer specific quirks/code out of the core,
  to make the core logic more readable and thus ease maintenance.
* Move the SFDP logic out of the core, it provides a better
  separation between the SFDP parsing and core logic.
* Trim what is exposed in spi-nor.h. The SPI NOR controllers drivers
  must not be able to use structures that are meant just for the
  SPI NOR core.
* Use the spi-mem direct mapping API to let advanced controllers
  optimize the read/write operations when they support direct mapping.
* Add generic formula for the Status Register block protection
  handling. It fixes some long standing locking limitations and eases
  the addition of the 4bit block protection support.
* Add block protection support for flashes with 4 block protection
  bits in the Status Register.

SPI NOR controller drivers changes:
* The mtk-quadspi driver is replaced by the new spi-mem spi-mtk-nor
  driver.
* Merge tag 'mtk-mtd-spi-move' into spi-nor/next to avoid conflicts.

HyperBus changes:
* Print error msg when compatible is wrong or missing
* Move mapping of direct access window from core to individual drivers
