Dear Otavio, Some boards don't have the DUART easily available (see STKa28 by TQ-group for instance) while a regular rs232 port is easily accessed. The purpose of this patch is more of a demonstration how to use the AUART driver and was requested by Fabio during the submission of the AUART driver.

Yes, correct. With this target in place, we can have a user of the mxs auart driver that Andreas submitted recently. Regards, Fabio Estevam

Dear Marek
> I wonder, why dont you add support for the TQ SoM in the first place?
I have plans to do it but I only have access to the board at work and
I currently am very busy so have limited time testing the board setup, so I don't
know when in time I will be able to submit such a patch.

Andreas
