Travis Geiselbrecht 8cf28bbdcf [arch][riscv] Initial port to a riscv32 sifive target

Currently targets qemu's sifive_e machine, which is a split flash/ram
machine, much like the Sifive HiFive1. Untested as of yet on a real
HiFive1.

Basic support including interrupts and architectural timers in place.

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
