Say Y here to include experimental MMCIF loading code in
romImage. With this enabled it is possible to write the romImage
kernel image to an MMC card and boot the kernel straight from
the reset vector. At reset the processor Mask ROM will load the
first part of the romImage which in turn loads the rest the kernel
image to RAM using the MMCIF hardware block.
