I too am interested in this. Can you point me to a link where to get the sources? Bob Piatek fishcamp engineering 105 W.

The configuration is the VL100 board, see http://www.denx.de/embedded-ppc-en.html It uses 2 Philips SC26x198 Octal UARTs and a slightly modified stallion multiport serial driver. I can send you the SC26x198 Octal UART driver sources if you want. > > What exactly is your problem? > It seems that that standard linux driver for 16550 UARTs relies very > much on i86 PC architeture. > During my first tries I couldn't tell him that my UART is NOT at 0x2f8 > or whatever. > So that's the problem.

What do you think? Look at existing board configurations. Most use just CONFIG_SERIAL, CONFIG_SERIAL_CONSOLE, CONFIG_SERIAL_EXTENDED, CONFIG_SERIAL_SHARE_IRQ. In our case there were no conflicts, because our SC26X198 _was_ a non-standard driver.
