Hi,
I'm starting to port UART driver on SH7727 T-Engine Board, what should I do?
+ How do I configure kernel?
+ What should files change?
These are some information which I get:
This is chip (EXAR ST16C2550) is controller in the UART control block:

I had datasheet.
Best regards

This device is already generically supported through the 8250 driver, so
you should only have to set up a platform device for it. Grep for
'serial8250' in arch/ and you can find plenty of examples for how to set
that up for your board.
