From cd8845d7a49687e9e7f727c9d821accf22854dd3 Mon Sep 17 00:00:00 2001 From: Steve Kipisz Date: Thu, 18 Jul 2013 15:13:03 -0400 Subject: am335x_evm: Add support for the NOR module on the memory cape This patch adds support for the NOR module that attaches to the memory cape for a Beaglebone board. This does not add booting support; only support so that you can boot from SD/MMC and see the NOR module so that it can be programmed.
