Ventana is a board which is very similar to Seaboard. Support it by
re-using board/nvidia/seaboard/seaboard.c with minor run-time conditionals.

v5: Makefile: Use cmd_link_o_target, remove unused clean/distclean targets.

another way to address this would be to add "__weak" to the existing 
gpio_config_uart() function, and add a gpio_config_uart() stub to 
board/nvidia/ventana/ventana.c.

although, if machine_is_ventana() returns a constant, and you marked 
gpio_config_uart_seaboard() static (i think you want to do that anyways), the 
code should come out the same.

sure, you get to maintain this, not me, so whatever is easier for you since 
the code size will be the same (once you fix the static issue)

well, the current one is wrong, so you need to post an updated patch before 
it'll get merged :)
