| 4 | Subject: [PATCH] mtd: spinand: macronix: Add support for MX31UF1GE4BC |
| 5 | |
| 6 | The Macronix MX31UF1GE4BC is a 1.8V, 1Gbit (128MB) serial |
| 7 | NAND flash device. |
| 8 | |
| 9 | Validated by read, erase, read back, write and read back |
| 10 | on Xilinx Zynq PicoZed FPGA board which included |
| 11 | Macronix SPI Host (driver/spi/spi-mxic.c). |
