[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...
