This series of patches will add initial supports for QPIC SPI NAND driver. Currently this driver support following commands -- RESET -- READ ID -- BLOCK ERASE -- PAGE READ -- PAGE WRITE -- GET FEATURE -- SET FEATURE -- BAD BLOCK CHECK This driver has been tested with dd command with read/write page with multiple file size 1MiB, 10MiB,40MiB etc. Also tested with "mtd" command like mtd erase, mtd write, mtd verify etc. Need help to test these all patches on SDX65 and SDX75 platform.
