+Subject: [PATCH] mtd: spinand: macronix: Add support for MX35LFxGE4AD
+
+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).
