[U-Boot-Users] PATCH: ixp42x UART: support 230400bps, enable RTS

[Michael Schwingen]

Hi,

the following patch
 - adds support for 230400bps
 - enables the RTS signal. No handshaking is done, but the active RTS signal
   allows to connect to the target using a PC which is using RTS/CTS
   handshake, and does no harm if the PC is set to ignore RTS.
