Hmm. That's all or most Tegra boards. What's the break?

That said, I wonder why we need CONFIG_API in the distro config; the
purpose of that config is to allow the "pxe" and "sysboot" commands not
to work. If we start supporting all kinds of other random boot
mechanisms, we'll just end up with a fragmented mess, rather than a
unified boot mechanism.
