    MIPS: Remove unused R6000 support · 3b2db173
    Paul Burton 提交于
    The kernel contains a small amount of incomplete code aimed at
    supporting old R6000 CPUs. This is:
    
      - Unused, as no machine selects CONFIG_SYS_HAS_CPU_R6000.
    
      - Broken, since there are glaring errors such as r6000_fpu.S moving
        the FCSR register to t1, then ignoring it & instead saving t0 into
        struct sigcontext...
    
      - A maintenance headache, since it's code that nobody can test which
        nevertheless imposes constraints on code which it shares with other
        machines.
    
    Remove this incomplete & broken R6000 CPU support in order to clean up
    and in preparation for changes which will no longer need to consider
    dragging the pretense of R6000 support along with them.
