Whilst U-boot does not require this itself, Linux currently relies upon it having been muxed and enabled by the bootloader. Thus in order to preserve compatibility with current kernels before a fix is merged in Linux we will enable the SERIRQ interrupt and mux it to its pin. Without doing this current kernels will never receive serial port interrupts and the end result is typically that userland appears to hang. Signed-off-by: Paul Burton <paul.burton@imgtec.com>
