The number used to be hard-coded to 64MB, which is still the default if the kernel option is not specified. However, 64MB is insufficient for using a large mdroot filesystem. The hard-coded number can't be safely increased because too large a number may run into memory-mapped IO space on some SoCs that must not be mapped as ordinary memory. END
