	  MMU starting from version 3 (found in ARC 770) and now
	  version 4 (found in ARC HS38) allows the selection of the
	  page size during ASIC design creation.

	  The following options are available for MMU v3 and v4: 4kB,
	  8kB and 16 kB.

	  The default is 8 kB (that really matches the only page size
	  in MMU v2).  It is important to build a toolchain with page
	  size matching the hardware configuration. Otherwise
	  user-space applications will fail at runtime.
