arm syscalls: add explicit dependency

Some syscall headers are generated during the build process, and jam is
not smart enough to add an automatic dependency.

kernel & addons: Build with the non-legacy GCC even on x86_gcc2h.

Only one code change: for some reason, GCC chokes on the cr3 functions
as macros (throwing errors about invalid registers.) The BSDs have them
as inline functions instead, so they are converted to that here.

Tested and working. There seems to be about a 10% decrease in CPU time
on some compilation benchmarks that I briefly tried.

system/uart: refactor debug_uart, fix arm uart

* Drop ArchUART8260 layer to reduce complexity. It's whole
existance in life was to adjust the mmio alignment.
* Fold architecture mmio alignment into DebugUart
* We could potentially pass a Init(int mmioAlignment)
arg in the future if the macros get too messy.
* Move Barrier code back a layer into DebugUART
* Fixes the arm uart and EFI build

arm: Add 8250 omap variant uart driver

* Untested, someone with an omap3,4,5 could though.

u-boot: Fix mmc build without target boards

ARM: kernel: introduce SoC abstraction

This introduces InterruptController and HardwareTimer classes to
handle the SoC specific implementations of timers and ints for
the ARM platform.

These could be improved and moved to a more 'generic' level once
we're confident they are 'good enough'.

NOTE: The OMAP timer implementation is fully untested and probably
completely non-functional....

ARM: sync up VM code with x86

No big functional reason for this, but rather keep it in sync now
then have to do lots of work later on, when there are major changes.
Once I have it fully fleshed out for ARM, I might take a look if
we can generalise it a little more, as there's lots of code
_exactly_ the same for both platforms (and other platforms in
progress using the same code).

ARM: kernel: Make 32/64-bit atomics work for ARMv5/6

Support for 64-bit atomic operations for ARMv7+ is currently stubbed
out in libroot, but our current targets do not use it anyway.

We now select atomics-as-syscalls automatically based on the ARM
architecture we're building for. The intent is to do away with
most of the board specifics (at the very least on the kernel side)
and just specify the lowest ARMvX version you want to build for.

This will give flexibility in being able to distribute a single
image for a wide range of devices, and building a tuned system
for one specific core type.

ARM: Initial implementation of interrupt/exception handling.

This contains both the common ARM(v5) vector handling as well as
the PXA(verdex) specific interrupt controller code, to be seperated
when ARM support for FDT is implemented.

Functional enough to handle interrupts, needs work on KDL support.

Preparation for merge of x86 and x86_64 kernel sources.

Since x86 and x86_64 share a lot of common code, x86_64 kernel sources/headers
are going to reside under headers/private/kernel/arch/x86 and
src/system/kernel/arch/x86 along with the existing x86 code. This commit
changes the build system to handle this. A new variable, TARGET_KERNEL_ARCH,
has been added. This is the name of the kernel/boot architecture directory
name, set to x86 on both x86 and x86_64. This is now used in all places where
TARGET_ARCH was used to get to kernel arch sources/headers (I've changed
everything necessary as far as I can tell). Kernel won't build for x86_64
at the moment as the sources have not been merged, loader does.

uart: Fix arm kernel build

* Make kernel use mmu_man's new UART code
* Remove no longer used uart.cpp / uart.h

arm uart: First work towards Amba serial driver

* Move Raspberry Pi board over to Amba driver
* Add initial set of registers and values
* Few small style cleanups

arm uart: Complete redesign of ARM uart code

* Add nested function wrappers to allow usage of other
uart drivers depending on board. We may want to use this
on other platforms at some point (haha, maybe)

* ARM: Major VM work
- This is mostly a copy of the x86 32bit paging method and infrastructure, this was copied for two reasons:
1) It is the most complete VM arch
2) The first ARM PAE patches have landed on alkml, so we will have to deal with it in the future as well,
and this infrastructure has proven to be ready ;)
- No protection features, or dirty/accessed tracking yet
- Lots of #if 0

but....

It boots all the way up to init_modules() now, and then dies because of a lack of (ARM) ELF relocation implementation!

Since at this point the VM can be fully initialised, I'm going to focus on CPU exceptions next, so we can get KDL to trigger
when it happens, and I can actually debug from there ;)
