  48           MMU starting from version 3 (found in ARC 770) and now
  49           version 4 (found in ARC HS38) allows the selection of the
  50           page size during ASIC design creation.
  51
  52           The following options are available for MMU v3 and v4: 4kB,
  53           8kB and 16 kB.
  54
  55           The default is 8 kB (that really matches the only page size
  56           in MMU v2).  It is important to build a toolchain with page
  57           size matching the hardware configuration. Otherwise
  58           user-space applications will fail at runtime.
