SPI NOR core changes:

Browse Source 
* introduce Read While Write support for flashes featuring several banks
 * set the 4-Byte Address Mode method based on SFDP data
 * allow post_sfdp hook to return errors
 * parse SCCR MC table and introduce support for multi-chip devices
 
 SPI NOR manufacturer drivers changes:
 * macronix: add support for mx25uw51245g with RWW
 * spansion:
   - determine current address mode at runtime as it can be changed in a
     non-volatile way and differ from factory defaults or from what SFDP
     advertises.
   - enable JFFS2 write buffer mode for few ECC'd NOR flashes: S25FS256T,
     s25hx and s28hx
   - add support for s25hl02gt and s25hs02gt

initialize the necessary fields for spi_nor{}. Please see
drivers/mtd/spi-nor/spi-nor.c for detail. Please also refer to spi-fsl-qspi.c
when you want to write a new driver for a SPI NOR controller.
Another API is spi_nor_restore(), this is used to restore the status of SPI
