[PATCH] ARM: 2686/2: AAEC-2000 Core support
Patch from Bellido Nicolas Core support for AAEC-2000 based platforms. This is an updated version of the previous patch, and takes into account Russell's comments. AAED-2000 default configuration will follow as soon as some problems with the bootloader are sorted out... Signed-off-by: Nicolas Bellido Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
