For 824x the detection code for the on-chip UART does NOT currently
detect it as a 16550A.  There is a patch that Tom Rini and I are
working on getting accepted by the serial maintainers, that should fix
this.

However, its not clear to me from your email if you also have a
ST16C2552 in addition to the DUART on the 8240.
