2010-01-14Added support for L2 (4K) page tables and made the CPU driver change ↵AJFISH
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. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9734 6f19259b-4bc3-4df7-8a09-765794883524
2010-01-13Adding a Debug version of the UncachedMemoryAllocationLib that will make the ↵AJFISH
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. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9725 6f19259b-4bc3-4df7-8a09-765794883524
2010-01-12Working on adding paging to the CpuDxe driver so it can update cachablity. ↵AJFISH
At this point it is coded, but untested. So this file is not yet hooked into the driver. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9721 6f19259b-4bc3-4df7-8a09-765794883524
2010-01-12One more header fixAJFISH

2010-01-12Fix some more headers. Add some missing library classes in .dec file and ↵AJFISH
update .dsc to default to cortex ARM cpu type. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9718 6f19259b-4bc3-4df7-8a09-765794883524
2010-01-12Updating ArmLib.h to add functions needed to turn on paging in CpuDxe. Also ↵AJFISH
added a protocol to enable debugging of DMA issues. DxeCpu driver will produce and the UncachedMemoryAllocationLib can consume. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9717 6f19259b-4bc3-4df7-8a09-765794883524
2010-01-12Need to add some extra functions to the libraries to support paging in the ↵AJFISH
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. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9716 6f19259b-4bc3-4df7-8a09-765794883524

2010-01-08Fixed a bug in the HardwareInterrupt handler that would blow the stack if ↵AJFISH
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. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9701 6f19259b-4bc3-4df7-8a09-765794883524

2010-01-08Adding support for a single stack, GCC check in will followAJFISH

2009-12-22Working on having a single stack for all modes. This code currently has an ↵AJFISH
issue nesting interrupts in a big honking loop, but seems to save and restore context correctly. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9587 6f19259b-4bc3-4df7-8a09-765794883524
2009-12-06Adding support for BeagleBoard. AJFISH
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). git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9518 6f19259b-4bc3-4df7-8a09-765794883524
