Kees Jongenburger 7e11828c6e arm:create SoC specific bsp directory and move code to there.
Created a new directory called bsp (board support package) to hold
board or system on chip specific code. The idea is the following.

Kees Jongenburger aa94c9ed55 arm:switch to dynamic configuration for the kernel.
During startup machine.board_id is now determined. The kernel can now
at runtime determine how to configure itself and does so.

Ben Gras 8e7c0604bd arm timer fix
. set 'done' once initialized so 32-bit read frc works,
	  thanks to keesj
	. make sure the software-implemented upper 32 bit of the 64-bit
	  "tsc" value works OK by adding an assert in one of its calls

Ben Gras 8ea66915f2 kernel: scheduling fix for ARM
. make read_tsc_64 use the free-running clock, significantly
	  improving scheduling behaviour

Thomas Veerman db8c1ee9d0 ARM: provide free running clock to replace ccnt
The Cycle CouNTer on ARM cannot be used reliably as it wraps around
rather quickly and can be altered by user space (on Minix). Furthermore,
it's buggy when wrapping and is not implemented at all on the Linaro
Beagleboard emulator.

This patch programs GPTIMER10 as a free running clock at 1.625 MHz (it
doesn't generate interrupts). It's memory mapped into every process,
which enables libsys to provide micro_delay().

Lionel Sambuc b1c4ba4ab6 ARM updates
Due to the ABI we are using we have to use the earm architecture
moniker for the build system to behave correctly. This involves
then some headers to move around.

There is also a few related Makefile updates as well as minor
source code corrections.
