[PATCH 1/1] arm: Fix unavailable MTD userland devices on Excito B3 boards

From: Gordon Bos <hidden>
Date: 2015-02-06 08:45:11
Subsystem: the rest · Maintainer: Linus Torvalds

Excito B3 boards use SPI flash for booting and several userland
functions require access to this flash memory, including power down
control. However /proc/mtd shows an empty list and the userland
tools respond with "device not found".

Change driver reference for spi@10600 to M25P80

Verified on my own Excito B3
