Some notes I have from a previous life which may be useful, but I'm
afraid I've no way of checking these days:

* CONFIG_DEBUG_UART=y
* CONFIG_DEBUG_UART_BASE=0x44e09000
* CONFIG_DEBUG_UART_CLOCK=48000000
* CONFIG_DEBUG_UART_OMAP=y
* CONFIG_DEBUG_UART_SHIFT=2
* CONFIG_DEBUG_UART_BOARD_INIT=y
* CONFIG_DEBUG_UART_ANNOUNCE=y
