ARM: 5831/1: ARM: U8500 core machine support Adds core support for the ST-Ericsson U8500 platform. It supports memory mappings, binds to the existing modules like GIC, SCU, TWD and local timers and sets up the infrastructure for the secondary core.

ARM: add an extra temp register to the low level debugging addruart macro Some platforms (like OMAP not to name it) are doing rather complicated hacks just to determine the base UART address to use. Let's give their addruart macro some slack by providing an extra work register which will allow for much needed cleanups. This is basically a no-op as this commit is only adding the extra argument to the macro but no one is using it yet.

ARM: debug: move PL01X debug include into arch/arm/include/debug/ Now that the PL01X debug include can mostly stand alone without requiring platforms to provide any macros, move it into the debug directory so it can be directly included. This allows us to get rid of a lot of debug-macros include files. The autodetect case for Versatile Express and the ux500 are left alone; these are more complicated implementations.
