Strong cryptography used for signing first stage bootloader,
undocumented interface and other stuff which initialize HW and
small memory (about 100kB) for second stage non-signed
bootloader. Next kernel image is limited to size 2MB. And
currently uboot can be compiled to act as "kernel" image, so
second stage bootloader can boot it.

I spend some time to replace second (non signed) bootloader with
something other, but really it is not possible.
