From 3df3bc1e1dc4c38de93d66fb589565f36d9749c7 Mon Sep 17 00:00:00 2001 From: pekon gupta Date: Tue, 22 Jul 2014 16:03:21 +0530 Subject: board/ti/am335x: add support for beaglebone NOR Cape This patch adds support of NOR cape[1] for both Beaglebone (white) and Beaglebone(Black) boards. NOR Flash on this cape is connected to GPMC chip-select[0] and accesses as external memory-mapped device. This cape has 128Mbits(16MBytes), x16, CFI compatible NOR Flash device. As GPMC chip-select[0] can be shared by multiple capes so NOR profile is not enabled by default in boards.cfg. Following changes are required to enable NOR cape detection when building am335x_boneblack board profile.
