Ack, we don't want hardware handshake enabled in U-Boot. But if I understand
this correctly, then this patch from Steven configures the RTS/CTS lines
correctly (they are multiplexed with other signals), so that they *can* be
used by the OS if needed. It doesn't enable hardware handshake in U-Boot.
Steven please correct me if I am wrong here.
Thanks.
