    MIPS: X1830: Add X1830 system type. · b9bb868e
    周琰杰 (Zhou Yanjie) authored
    1.Add X1830 system type for cat /proc/cpuinfo to give out X1830.
    2.Change "PRID_IMP_XBURST" to "PRID_IMP_XBURST_REV1" and add a
      new "PRID_IMP_XBURST_REV2" for new Ingenic CPUs which has
      XBurst with MXU2 SIMD ISA.
    
    Notice:
    1."PRID_IMP_XBURST_REV2" is corresponds to the latest XBurst
      processor with 128bit MXU2 SIMD instruction set, not the upcoming
      XBurst2 processor. This version of the processors fixes issues
      such as BTB and HPTLB.
    2.In order to simplify and reuse the code, the "c->cputype" and
      the "c->writecombine" and the "__cpu_name[cpu]" in the original
      "PRID_IMP_XBURST" (now is "PRID_IMP_XBURST_REV1") are removed,
      and the corresponding settings are abtained through fall-through
      to "PRID_IMP_XBURST_REV2", which will cause the name that was
      previously mistakenly called "JZRISC" to become to the real name
      "XBurst".
