- Sync the code a lot closer to its x86 counterpart, still more work to be done.
- Very soon, it should be possible to share upward of 50% of the new ARM code with the x86 version of React as well and unify the implementations.

- This means we actually load and parse drivers now!!! Some Mm work was required to support unloading and remapping: MmDeleteVirtualMapping is now implemented.
- We can now see scsiport.sys and atapi.sys strings displayed on the LCD.
- Implemented HalQuery/SetDisplayParameters, HalQuery/ReleaseDisplayOwnership and HalDisplayString just like on x86.
- Since we now load symbols for the drivers (or at least try to), stubbed DebugService2, which also shows us what's being loaded.
- Extended the Loader MemoryType array to include XIP/RAM Disk Memory.

- Fix a bug in MmDeletePageTable.
- Use MmCreateVirtualMappingForKernel when we are already in the right process context, and allow it to be used for addresses < KSEG0_BASE as well.
- We now have full memory mapped file support, and get all the way to CmInitSystem1.

- Don't hang in the clock interrupt anymore, for now we'll just ignore it (but it works! :D)
- Make all unimplemented bootvid functions hang the system, so we can better stop at progress-points.
- Implement VidInitialize:
- We allocate a 640x480@16bpp framebuffer using contiguous physical memory (our MMU code survives!).
- We setup the LCD controller timings and framebuffer address.
- We enable the LCD
- For debugging, we're also drawing a nice little test pattern... and it works! We have GUI Code :)

- Get rid of KeSwapIrql -- both lower and higher IRQL handling was treated the same!
- We can now re-activate the assert in the IRQL code
- Disable interrupts before changing the interrupt mask!!!
- And re-enable them solely if they were enabled.
- Clear interrupts mask before setting a new one -- raising isn't always additive!
- Fix KiInterruptHandler to perform operations in the right order.
- Finish implementing interrupt exit code.
- Code KeArmStatusRegisterGet to read CPSR and interrupt status.
- Make debug prints a lot more readable and dont trying to acquire the stack during pool allocations.
- Setup the clock interval timer!!!
- This code regresses progress but makes stuf fwork right. We'll get better after implementing the stall interrupt.

- There is no reason to implement the Interlocked* APIs in assembly in the kernel -- just have them call the intrinsics.
- Also fix the way we were overloading the exported APIs, we now use the intrinsics all the time.
- Convert loader block address to virtual, and parse the addresses inside it and convert them to virtual too, after we don't use them in FreeLDR anymore -- the kernel will delete the p->v identity mapping, and eventually still need to touch the loader block.
- Implement MmGetPhysicalAddress and MiGetUserPageDirectoryCount for ARM.
- We now reach the point where we start initializing the boot drivers' memory information.

- Implemented and defined the MMU-OS architecture for the ARM port. The details are too long for a commit message, but we have decided to replicate the x86 NT memory manager layout. We've defined a PTE_BASE at 0xC0000000 just like on x86, and we use a PDE_BASE at 0xC1000000. Unlike the x86, we can't use PDE-PTE self-mapping because ARM has different formats (and sizes!) for PDE vs PTEs! We emulate the behavior however (which adds a small performance hit) and the Mm porting is thus at least 10 times easier.
- Moved serial port to 0xE0000000 for now.
- We now parse the board memory map from u-boot.
- Added memory allocation code to FreeLDR -- we now build a full ARC memory map for the kernel.
- FreeLDR allocates page tables and sets up the initial support for our memory layout (see comments for some lengthier explenations)
- Allocations made by FreeLDR for loading ReactOS are now made from a "shared heap" page that's also marked in the memory map.
- Registry and NLS data are now being put into the loader block.
- We now create a loader entry for the kernel (but not anything else -- we'll have to parse the list properly later).
- Defined correct _HARDWARE_PTE_ARM and _MMPTE_HARDWARE for ARM.
- ARM_COARSE_PAGE_TABLE is now 4KB instead of 1KB, going against the architecture! We do this for proper OS support of the PTE_BASE.
- Fixed build due to KiSystemStartulReal change.
- Fixed a bug on the x86 build when creating memory allocation descriptors. Memory corruption could occur in certain scenarios.
- Implemented significant portions of the ARM memory manager code in the kernel:
- MmGetPageDirectory.
- MmDeletePageTable (for the kernel address space only).
- MmIsPagePresent (for the kernel address space only).
- MmCreateVirtualMappingForKernel.
- MmCreateVirtualMapping (calls MmCreateVirtualMappingUnsafe).
- MmCreateVirtualMappingUnsafe (for the kernel address space only).
- MmSetPageProtect (unused on ARM).
- MmCreateHyperspaceMapping.
- MmDeleteHyperspaceMapping.
- MmInitGlobalKernelPageDirectory.
- MmInitPageDirectoryMap.
- With the above, this means we now go well inside MmInit1: the PFN database is setup and works, memory areas are functional, and non-paged pool is fully working.
- We currently hit a data abort during paged pool setup -- this is to be expected, since we don't have any exception handlers yet. These are coming up next -- we have to start handling crashes (and page faults).

Make a specialized UNIMPLEMENTED for Mm code so we don't go too far into the boot with 100 failures hanging behind our backs, which makes it hard to debug progress.
svn path=/trunk/; revision=32351
Add exp.c for ARM. Stub out KeContextToTrapFrame in C.
Add thrdini.c for ARM and implement KeArmInitThreadWithContext -- may require changes if the exception frame structure isn't preserving all we need. Stub out KiThreadStartup in C.
