Thank you both for your suggestions. I'm going to try Ross way, so I'm
doing platform-level ports and will try to support the different boards
using CDL options (will do and try that later on, first the porting is
more important for me).

I was referring to the polling-based simple UART driver, that seems to
be somewaht common to ARM9 ports. The driver is implemented on the
platform level. But I'll write about that in a second mail.

Thanks for your suggestions and help!
Cheers,
