-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.
