[PATCH 20/39] ARM: u300: add FSMC flash into the device tree
Linus Walleij
linus.walleij at stericsson.com
Fri May 31 05:18:55 EDT 2013
From: Linus Walleij <linus.walleij at linaro.org>
This registers the U300 FSMC flash controller from the
device tree, and defines the three partitions. Skip the
BBT scan as in the current platform data.
