[RFC PATCH 0/10] Initial MX53 support

Hi!

This patch series adds support for the i.MX53 chip. MX53 is a derivative of MX51
with a few new features.

A major change from MX51 is the support for 2GB of RAM. This has resulted in all the
peripheral addresses changing. Fortunately the AIPS and SPBA buses are just
shifted down by 0x20000000, but the module offsets within the buses are the same
as MX51. Rather than create new defines of every peripheral register base, I
fix-up the addresses at runtime for MX53. I am interested in comments on this
approach.

With the runtime physoffset patches, both MX51 and MX53 can boot with a single
image.

Regards,
Rob
