Subject: [PATCH] mtd: spinand: macronix: Add support for MX35LFxGE4AD
commit 5ece78de88739b4c68263e9f2582380c1fd8314f upstream.
The Macronix MX35LF2GE4AD / MX35LF4GE4AD are 3V, 2G / 4Gbit serial
SLC NAND flash device (with on-die ECC).
Validated by read, erase, read back, write, read back and nandtest
on Xilinx Zynq PicoZed FPGA board which included Macronix SPI Host
(drivers/spi/spi-mxic.c).
