Added support for L2 (4K) page tables and made the CPU driver change cachability attributes on request. Also got the DebugUncache infrastructure working for the first time. Looks like it works for the simple case. Checking in so we can get more eyes looking at the code.

Adding a Debug version of the UncachedMemoryAllocationLib that will make the PCI DMA address not match the CPU C address for a DMA buffer. The PCI DMA address will generate a page fault if accessed from the CPU. This should make it easy to debug EFI DMA code to make sure it is following the correct rules for which pointer to use.

Working on adding paging to the CpuDxe driver so it can update cachablity. At this point it is coded, but untested. So this file is not yet hooked into the driver.

Updating ArmLib.h to add functions needed to turn on paging in CpuDxe. Also added a protocol to enable debugging of DMA issues. DxeCpu driver will produce and the UncachedMemoryAllocationLib can consume.

Need to add some extra functions to the libraries to support paging in the 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.

Fixed a bug in the HardwareInterrupt handler that would blow the stack if 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.

Adding support for BeagleBoard.
...
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).
