[RFC][PATCH 00/10] Base support for Freescale i.MX51 SoC platform

[Amit Kucheria <amit.kucheria@canonical.com>]

This series of patches adds basic support for i.MX5 family to the kernel. The
target device is the i.MX51-based Babbage board (v2.5+) since that is the
hardware I have access to.

This is a result of dropping a lot of functionality from the existing
Freescale codebase that is shipping as part of the Ubuntu ARM enablement. A
lot of the code was refactored to use facilities that were already available
upstream in arch/arm/plat-mxc/. The hope is to get this base port into
mainline and then start working on mainlining the drivers.

With regards to the splitting of the patches, I felt that the following
patchset made it easy to review code. But if this is not acceptable and some
of these patches need to be merged into a single patch, I can do that too.

Regards,
Amit
