[U-Boot] cuImage and multi image?

No. I don't have to. Right? The link_address is still 0x400000.

Mine is a cuImage. I'm pretty sure that my ramdisk is valid when it's
a separate image. I used "bootm <kernel_addr> <ramdisk_addr>" to boot.

In the previous run the ramdisk image was corrupted because the single
image was loaded at 0x800000. But the boot message showed that the
initrd image was at 0x0066c000-0x009ae825. So it was over the 8MB
area.

However after the load address was changed to 0x04000000 (64MB), the
ramdisk still seemed corrupted but with different error messages.
