45 help
46 Say Y here if your bootloader sets the SROMLL bit(s) in
47 the SDRAM controller, organizing memory as a contiguous
48 array. This option will disable CONFIG_DISCONTIGMEM and
49 force the kernel to manage all memory in one node.
50
51 Setting this option incorrectly may prevent the kernel from
52 booting. It is OK to leave it N.

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