With the release of the new Aptiv cores from MIPS Technologies, Inc.
the ASID size must be determined at boot time and cannot simply be
hardcoded as before. This has been tested on our Malta and SEAD-3
platforms with 1004K, 1074K, M14KEc, proAptiv and interAptiv cores.

Steven J. Hill (2):
  MIPS: Allow ASID size to be determined at boot time.
  MIPS: microMIPS: Support dynamic ASID sizing.
