New Revision: 256170
URL: http://svnweb.freebsd.org/changeset/base/256170

Log:
  Add two new MIPS CPU families - mips24k and mips74k.
  
  They're both different cores:
  
  * mips24k is an 8-stage pipeline, mips32r1 ABI, non-superscalar core.
  * mips74k is a dual-issue 15-stage superscalar design, mips32r2 ABI.
  
  They have different sets of quirks and bugs; these #define entries
  will be used to work around these.
  
  Now, strictly speaking, we should have CPU ABI families (mips32r1, mips32r2,
  etc) and CPU core types (mips4k, mips24k, mips74k, etc.)  But this is the
  starting point of that particular tidy-up.
