| Subject: [PATCH] mtd: spinand: macronix: Add support for MX31LF1GE4BC |
| |
| The Macronix MX31LF1GE4BC is a 3V, 1Gbit (128MB) serial |
| NAND flash device. |
| |
| Validated by read, erase, read back, write and read back |
| on Xilinx Zynq PicoZed FPGA board which included |
| Macronix SPI Host (driver/spi/spi-mxic.c). |
