Ian,
sorry for not replying earlier, but isn't that a bug-fix against the
generic U-Boot? In that case, it's probably wise to post it on the
u-boot mailing list :)
Other then that, I think i fixed most sunxi specific compile errors and
that one has been annoying me for ages :)

In do_gpio value is not initialised in the GPIO_OSCILLATE case:

return value;

Returning 0 in this case seems fairly logical.
