Subject: [PATCH] mtd: spinand: Add support for XTX XT26xxxDxxxxx
Date: Sat,  7 Oct 2023 05:09:54 -0400	[thread overview]
Message-ID: <20231007090954.4569-1-bruce_suen@163.com> (raw)

Add Support XTX Technology XT26G01DXXXXX, XT26G11DXXXXX, XT26Q01DXXXXX,
XT26G02DXXXXX, XT26G12DXXXXX, XT26Q02DXXXXX, XT26G04DXXXXX, and
XT26Q04DXXXXX SPI NAND.

These are 3V/1.8V 1G/2G/4Gbit serial SLC NAND flash device with on-die
ECC(8bit strength per 512bytes).
