+Subject: [PATCH] mtd: spi-nor: enable stateless 4b op codes for mx25u25635f
+
+All required stateless 4-byte op codes are supported by this flash
+chip. The stateless 4-byte support can't be autodetected due to a
+missing 4-byte Address Instruction Table in SFDP.
+
+Fixes hangs on reboot for SoCs expecting the flash chip in 3byte mode.
