Fabio Estevam bb07d7511e ARM: mx3: Setup AIPS registers 
It was observed on a mx31pdk board that audio playback only worked when the bootloader was Redboot, and
did not work when U-boot was used.

Comparing the sources of these bootloaders showed that the AIPS registers were not setup in U-boot.

Instead of relying on the bootloader to setup the AIPS registers, do it in the kernel so that audio
playback can work independantly of the bootloader being used.

Copied the AIPS settings from Redboot to the kernel.

Fabio Estevam 059e58f6f3 ARM: imx: Introduce generic function for displaying silicon revision 
Currently each i.MX processor has its own function for displaying the silicon
revision.

Introduce a generic function for this purpose, so that all i.MX processors can
reuse it.

Sascha Hauer 198016e1b1 [ARM] MXC: add cpu_is_ macros 
We had hardcoded cpu_is_ macros for mxc architectures till now. As we
want to run the same kernel on i.MX31 and i.MX35 this patch adds cpu_is_
macros which expand to 0 or 1 if only one architecture is compiled in and
only check for the cpu type if more than one architecture is compiled
in.
