        I believe that is the UART used by u-boot and the kernel -- essentially
a console debug port, though it may be available under Linux (the SRM is
confusing... That connector appears to be UART1, while UART3/5/8/10 go to
P8 and P9, variously, and the PRU UART0 [PRU1 and PRU2] go to P8). No idea
where UART2/4/6/7/9 go...
