There is no RAM here. That is in the IOMEM > space. Looks like a dirty trick to mount the initrd directly from the boot device remap which is at 0xf8000000 by default. Copying the image from the boot device to ram in u-boot and pass the correct initrd address should help here. Or we need a mbus ranges entry for it, too.
