Hi!

> PXA serial ports have "standard" UART names (ttyS[0-3]), major
> device number (4) and first minor device number (64) by default.
> 
> If the system has extra 8250 serial port hardware in addition
> to onboard PXA serial ports, default settings produce a device
> allocation conflict.
> 
> The patch provides a configuration option which can move onboard
> ports out of the way of 8250_core by assigning a different (204)
> major number and corresponding device names (ttySA[0-3]).

Yes, please. I was hitting the same issue with Sharp Zaurus and bluetooth
CF card... Bluetooth card had 8250 inside...
