Hi All,

Winbond has come up with special flash i.e. W25M161AW. It consist of Serial NOR(Die #0) and Serial NAND(Die #1) flash.
Means both NOR, NAND flashes are placed in W25M161AW controlled by single chip-select.

"Software Die Select (C2h)" command is being used to switch die or flash.

It looks to be quite unique chip and wondering if any kind framework or work in progress available to handle it.
I know that SPI-NAND framework discussions is still in progress.

Regards,
Prabhakar
