+	help
+	  Say Y here if your bootloader sets the SROMLL bit(s) in
+	  the SDRAM controller, organizing memory as a contiguous
+	  array.  This option will disable CONFIG_DISCONTIGMEM and
+          force the kernel to manage all memory in one node.
+
+	  Setting this option incorrectly may prevent the kernel from
+	  booting.  It is OK to leave it N.

+	  Say Y here to produce compact memory node tables.  By
+	  default pairs of adjacent physical RAM banks are managed
+	  together in a single node, incurring some wasted overhead
+	  in the node tables, however also maintaining compatibility
+	  with systems where physical memory is truly contiguous.
