+Subject: [PATCH] mtd: spinand: Add support for XTX XT26G0xA
+
+Add support for XTX Technology XT26G01AXXXXX, XTX26G02AXXXXX and
+XTX26G04AXXXXX SPI NAND.
+
+These are 3V, 1G/2G/4Gbit serial SLC NAND flash devices with on-die ECC
+(8bit strength per 512bytes).
+
+Tested on Teltonika RUTX10 flashed with OpenWrt.
+
+Datasheets available at
+http://www.xtxtech.com/download/?AId=225
