Subject: [PATCH v2 0/2] Add fixups for two-plane serial NAND flash 

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

Macronix serial NAND flash with a two-plane structure
requires insertion of Plane Select bit into the column
address during the write_to_cache operation.

Additionally, for MX35{U,F}2G14AC, insertion of Plane
Select bit into the column address is required during
the read_from_cache operation.

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