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