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 sparse memory support
|
|
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.
