      Fix some polling issues:
      
       - Don't background-poll disabled TAPs ... this was just a bug
         waiting to happen.  (And then it happened!)
      
       - Don't fail command line polls of disabled taps; that's not any
         kind of error, it's just that you can't do much.  But do show
         that tap-disabled status.
      
       - Spell "continuous" correctly in the variable name.  ;)
      
      Not resolved by this patch:  the need for an interlock whereby
      other code (like the JTAG layer) can block all other access to
      the JTAG layer, e.g. while enabling or disabling TAPs.  And
      that interlock needs to be timer-safe...

      Further cleanup to MIPS target read/write memory function: · 7fdce0e8
      zwelch authored
      - Move the mips32_..._read_mem calls to top-level of read_mem function.
      - Change: Only perform mips_m4k_read_mem conversion when retval == ERROR_OK.  
         - Prevents pointless conversions of bogus read values after failures.
      - Eliminate retval variable from mips_m4k_write_mem; return directly.
      - Move declaration of retval variable to point of first use.
      - Remove the now redundant switch statements testing size:
        - argument sanitizing already covers these cases.

      This patch helps fix MIPS big endian (elf32-tradbigmips) targets.
      If "-endian big" is not set in target create, the endianess defaults to
      little.  mw and md commands will still work, but binary file loads will
      have the incorrect word order loaded into memory.
      
      The EJTAG processor access data register (PrAcc) is little endian
      regardless of the CPU endianness; it is always loaded LSB first. This
      is confirmed by the fact that mips_ejtag_drscan_32() uses buf_set_u32()
      to load the scan field; buf_set_u32() is a little-endian formatter. For
      big endian targets, data buffers have to be modified so the LSB of each
      u32 or u16 is at the lower (first) memory location.  If the drscan
      out_value word order is set using buf_set_u32() then it makes sense to
      also fixup the in_value with buf_get_u32(); a symmetry argument. This
      has no affect on little endian hosts.
