[PATCH v2] mtd: spinand: macronix: Add support for serial NAND flash

From: Cheng Ming Lin
Date: Wed Jun 05 2024 - 01:50:27 EST


From: Cheng Ming Lin <chengminglin@xxxxxxxxxxx>

commit c374839f9b4475173e536d1eaddff45cb481dbdf upstream.

MX35UF{1,2,4}GE4AD and MX35UF{1,2}GE4AC have been
merged into Linux kernel mainline through upstream commit.

For SPI-NAND flash support on Linux kernel LTS v5.4.y,
add SPI-NAND flash MX35UF{1,2,4}GE4AD and MX35UF{1,2}GE4AC in id tables.

Those five flashes have been validated on Xilinx zynq-picozed board and
Linux kernel LTS v5.4.y.
