added a protocol to enable debugging of DMA issues. DxeCpu driver will produce and the UncachedMemoryAllocationLib can consume.

CpuDxe driver (still working on that). Also looks like some of the .INF file hade the token used to search replace the copyright headers and not the headers so I updated that.

you reenable interrupts in the TimerHandler. It should be noted this happens as the TimerHandler raises and restores TPL for the timer tick used by the DXE Core. There was some work around code in the CPU driver to prevent interrupts from being enabled while handling exceptions. This has been removed.

issue nesting interrupts in a big honking loop, but seems to save and restore context correctly.

ArmPkg - Supoprt for ARM specific things that can change as the architecture changes. Plus semihosting JTAG drivers.
EmbeddedPkg - Generic support for an embeddded platform. Including a light weight command line shell.
BeagleBoardPkg - Platform specifics for BeagleBoard. SD Card works, but USB has issues. Looks like a bug in the open source USB stack (Our internal stack works fine).
