Have you read this thread ?

It discusses your about your board, on which interrupts must be set to LEVEL
and not EDGE. BTW, they also used 8250. I don't know how you have to configure
the serial ports though.
This boot log also confirms that you have to use 8250/16550 :

It's not necessarily a default option. There are many console and serial
ports combination available. BTW, you could also try netconsole which will
send you the console data over an ethernet port if you cannot get the serial
to work.

ok.

ok.
