Subject: [PATCH 0/5] Add QPIC SPI NAND driver

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.
