commit c36408328c4d9ad10d835795f34af6a8b2b13771
Author: Thaminda Edirisooriya <thaminda at google.com>

riscv-spike: support for Spike emulation of riscv
Spike support: QEMU RISCV is broken, and the maintainers at Berkeley
are working on it, but at the moment spike is the only way to test
on riscv. Add support for spike console output for debugging.
Privileged ISA: Update to privileged ISA in RISCV (machine,
supervisor, hypervisor, user modes) broke exisitng RISCV asm, and
bootblock.S was updated to match the new spec. Clean old assembly
