-+	help
-+	  IFX extension for reserving (splitting) cache ways among VPEs. You must
-+	  give kernel command line arguments vpe_icache_shared=0 or
-+	  vpe_dcache_shared=0 to enable splitting of icache or dcache
-+	  respectively. Then you can specify which cache ways should be
-+	  assigned to which VPE. There are total 8 cache ways, 4 each
-+	  for dcache and icache: dcache_way0, dcache_way1,dcache_way2,
-+	  dcache_way3 and icache_way0,icache_way1, icache_way2,icache_way3.
-+
-+	  For example, if you specify vpe_icache_shared=0 and icache_way2=1,
-+	  then the 3rd icache way will be assigned to VPE0 and denied in VPE1.
-+
-+	  For icache, software is required to make at least one cache way available
-+	  for a VPE at all times i.e., one can't assign all the icache ways to one
-+	  VPE.
-+
-+	  By default, vpe_dcache_shared and vpe_icache_shared are set to 1
-+	  (i.e., both icache and dcache are shared among VPEs)
