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 -- Alex Kiernan
