But I tested it:-)

It seems that U-Boot just ignores the unknown command (well, it prints
an error that I didn't notice) and continues on. So, it kinda works but
certainly doesn't do what's intended;-)

Thanks for pointing out the issues. I'll also have to revise the
Raspberry Pi patches that have the same issue.
