ARMv7: Rewrote serial drivers on ARM.

They're now fairly well compartmentalised on both ARM and x86, and can start
automatically from Kaluga. There's also a 'kernel' serial driver, which uses
the syscall interface to read and write on the kernel console. This avoids
having user level and kernel code racing on access to the UART. Fish works
(minus line editing) on all Versatile Express platforms.

ARMv7: All existing platforms boot again

We're going to have to do something about usbboot though, it *really* wants to
jump at the beginning of the loaded image+0x1000, which is really hard to
achieve without buggering up alignments.

ARMv7: Separated pre-MMU init code

The ARMv7 initialisation is now divided strictly into a pre-MMU phase and a
post-MMU phase, with the jump to arch_init_2 being a calculated long jump.
This doesn't make much difference on the Pandaboard and other platforms with
RAM at 0x80000000, but it makes it possible to support other RAM locations
with little or no change to the code. This will be necessary for the Zynq.

There's a little assorted cleanup included in this patch, of the MMU init
code.

ARMv7: Improved cache code.

Moved a lot of cache manipulation into C, and started using clean and
invalidate correctly. We're still *very* gung-ho about flushing the cache.

ARMv7: Rationalised coreboot structures.

Put the Multiboot header in the coredata struct, and allocate both in and the
globals (which now contains only the printf spinlock) in the BSP kernel's BSS.
We no longer rely on magic addresses.

Doing so exposed a latent bug, where code using the various alloc_phys()
functions were assuming that the output would be page-aligned, when that
wasn't guaranteed. Added alloc_phys_aligned to all relevant prototypes.

Moved ARMv7 platform quirks to kernel arguments

This lets us ditch two trivial platform files (plat_fvp and plat_gem5).

Signed-off-by: David Cock <david.cock@inf.ethz.ch>

Rationalised the ARM Platform code.

We now have separate targets for the GEM5 VE and FVP VE, as the GEM5 version
actually simulates an A15, and has a few quirks. The FVP VE and Pandaboard
targets share most of their code. Thus we've got three ARMv7-A targets now,
and it should be easy to add more, as soon as we've got the simulators.
