[U-Boot] UART2 Console in u-boot

[prathika <prathika@deeopl.com>]

hi,
Thanks for that reply.
i have ported u-boot this way to my board with few changes in the u-boot 
source code and the board is up and i have tested stand alone 
application execution also.

Now as my requirement is that my console should be on UART2 as my UART0 
and UART1 are coming out as RS 422 lines and only UART2 is RS232. I did 
some patch up work on UART0 lines and tested my u-boot porting.

I added a line

#define UART2_BASE	CFG_PERIPHERAL_BASE + 0x500

I have now changed as below and I commented checking for #define 
UART0_CONSOLE and #define UART1_CONSOLE:

#define UARTBASE	UART2_BASE

Is this OK??

Thanks & Regards,
Prathika R
