[PATCH 0/3] Add fixups for two-plane serial NAND flash

[Cheng Ming Lin]

From: Cheng Ming Lin <chengminglin@xxxxxxxxxxx>

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.

In spinand.h, add struct spi_nand_fixups as SPI NAND
fixup hooks.

In macronix.c, add fixup functions and update ID table.

In core.c, add an if statement to determine whether to
insert the Plane Select bit for the column address.

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