  41           Say Y here if your bootloader sets the SROMLL bit(s) in
  42           the SDRAM controller, organizing memory as a contiguous
  43           array.  This option will disable CONFIG_DISCONTIGMEM and
  44           force the kernel to manage all memory in one node.
  45
  46           Setting this option incorrectly may prevent the kernel from
  47           booting.  It is OK to leave it N.

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