[PATCH 0/3] Add support for MIPS Allegrex

[david@davidgf.es]

From: David Guillen Fandos <david@davidgf.net>

These patches add minimal support for MIPS Allegrex CPU (present in
Sony's Playstation Portable devices). They provide the bare minimum
needed for a port. In particular they enable GCC support for the CPU.

I tried to keep the patches small and readable, however the testsuite
requires some rather lengthy files.

David Guillen Fandos (3):
  Add Allegrex CPU as a MIPS2-based CPU
  Add rotation instructions to allegrex CPU
  Adding more instructions to Allegrex CPU
