Kumar,
There is no DUART on the MPC8240, if 8240 is what he literally
meant. Some boards, like Unity, used to have an external DUART
for this reason.

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.

Hi,all,
Does Linux support UART ST16C2552 ?
There is a UART ST16C2552 on my board with CPU ppc8240.
While the linux system booting,sometimes function autoconfig(struct
serial_state * state) in ./drivers/char/serial.c detected
ST16C2552 as
quoted
16450,sometimes as 8250,can anyone tell me why?

Thanks for the correction. I guess my comments really apply to 8241,
8245 and 8540 then.
