[PATCH RFC 0/4] Add support for Microwatt-based SoCs

[Paul Mackerras]

This patch series adds support for running Linux on a Microwatt SoC
(system on chip) implementation on an FPGA.  Microwatt is a small
Power ISA implementation, targetted at FPGAs, aiming for PowerISA
v3.0B compliance.  It does not currently implement any floating-point
or vector instructions, hypervisor mode, big-endian mode, 32-bit mode,
or the HPT/SLB MMU facilities.  However, it does support enough to run
Linux (as of my "mmu" branch plus Ben's "litedram" branch").
