      [ARM] Set bit 4 on section mappings correctly depending on CPU · 8799ee9f
      Russell King 提交于
      On some CPUs, bit 4 of section mappings means "update the
      cache when written to".  On others, this bit is required to
      be one, and others it's required to be zero.  Finally, on
      ARMv6 and above, setting it turns on "no execute" and prevents
      speculative prefetches.
      
      With all these combinations, no one value fits all CPUs, so we
      have to pick a value depending on the CPU type, and the area
      we're mapping.
