[U-Boot-Users] USART on at91rm9200

[Leonid]

As I already wrote, for my project I need some USART functionality DBGU
doesn't have. For the time being I just wanted to verify USARTs are
working at all and using them as serial ports on u-boot looked for me as
a simplest test...
Probably I was wrong...

Why not use the DBGU?
I have never ever tested U-Boot with one of the std USARTs so I am not
surprised if people have problems...
