Travis Geiselbrecht 37918306f8 [external][arm][cmsis] reapply the systick patch to cmsis

SysTick_Config() tries to set the systick priority to max. Comment out
this line since arch/arm/arm-m/arch.c sets the priority to medium to
compete with the rest of the exceptions in the system.

LK

The LK embedded kernel. An SMP-aware kernel designed for small systems.

See https://github.com/littlekernel/lk for the latest version.

See https://github.com/littlekernel/lk/wiki for documentation.

Builds

To build and test for ARM on linux

install or build qemu. v2.4 and above is recommended.
install gcc for embedded arm (see note 1)
run scripts/do-qemuarm (from the lk directory)
you should see 'welcome to lk/MP'

This will get you a interactive prompt into LK which is running in qemu arm machine 'virt' emulation. type 'help' for commands.

note 1: for ubuntu: sudo apt-get install gcc-arm-none-eabi or fetch a prebuilt toolchain from http://newos.org/toolchains/arm-eabi-5.3.0-Linux-x86_64.tar.xz
