From b0fcb4b413028376894feaaaf62bcb09ab1b52f2 Mon Sep 17 00:00:00 2001 From: Mathias Kresin Date: Thu, 13 Apr 2017 09:23:54 +0200 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.
