FreeBSD needs a build of u-boot that adds the CONFIG_API option so that
loader(8) works.  From what I've heard, recent versions of u-boot have
broken the CONFIG_API option as part of the "device model" work.  So a
u-boot new enough that usb keyboards work on rpi is probably too new to
work with our need for CONFIG_API.

Our path forward probably involves abandoning CONFIG_API (since they
seem disinclined to support it) and using the new EFI support u-boot
provides.  But we don't have an EFI loader for armv6 yet either (and I
don't know that anybody has worked on that yet).
