Subject: [PATCH 2/2] mtd: spinand: macronix: Add support for serial NAND flash

From: Cheng Ming Lin <chengminglin@...c.com.tw>

MX35{U,L}F{2,4}G24AD-Z4I8 are Macronix serial NAND flashes.

Their main difference from MX35{U,L}F{2,4}G24AD lies in
the plane number. The plane number for those with the
postfix Z4I8 is 1.

These flashes have been validated on Xilinx zynq-picozed
board which include Macronix SPI Host.
