> JESD216B defines Sector Map Parameter Table. It identifies the
> location and size of sectors within the main data array of the
> flash memory device and identifies which Erase Types are supported
> by each sector. This table is used when a memory device has sectors
> of more than one size Or, does not allow all Erase Type commands to
> be applied to all sectors.
> This patch-set add support of Sector Map Parameter Table parsing.
> It also update framework to support read/write anyreg commands
> required by S25FS512S flash.
> Tested with "S25FS512S" flash and by over-riding fsl_qspi_read_anyreg()
> return with desired configuration id i.e. 0x05. Flash was
> pre-programmed for Uniform 256-kB sectors via non-volatile registers.
