Date: Wed, 4 Nov 2020 19:47:22 +0800 From: YouChing Lin <ycllin@...c.com.tw> To: miquel.raynal@...tlin.com, richard@....at, vigneshr@...com Cc: juliensu@...c.com.tw, gch981213@...il.com, linux-mtd@...ts.infradead.org, linux-kernel@...r.kernel.org, ycllin@...c.com.tw 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).
