Why to use AUART for console? can you elaborate it a little more?

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.
Best regards Andreas Wass

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

Good :-)

I wonder, why dont you add support for the TQ SoM in the first place?
Best regards, Marek Vasut

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.

Sucks, but ok.
