[U-Boot] [PATCH 2/5]P2020RDB Second UART port added for MPC85xx, MPC83xx, MPC86xx processors

[harsh poshtiwala]

Hi Poonam,

I am working on MPC8379 based board. I would like to enable the
support for the multiple serial port.

I would like to do it without changing the environment variable from
the console.

i.e I don't want to type setenv stdin and setenv stdout

I want to use two serial ports independently.

i.e whenever I type some of my custom command it should go to serial
port 2 and all the other command should go to console.

How do I achieve this?

Regards
