44    help
45      Say Y here if your bootloader sets the SROMLL bit(s) in
46      the SDRAM controller, organizing memory as a contiguous
47      array. This option will disable sparse memory support
48          and force the kernel to manage all memory in one node.

50      Setting this option incorrectly may prevent the kernel
51      from booting. It is OK to leave it N.

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

66      Setting this option incorrectly may prevent the kernel from
67      booting. It is OK to leave it N.
