I too am interested in this. Can you point me to a link where to get
the sources?

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.

But it's being used on a couple of PowerPC boards, you just have to
configure it correctly ;-)

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.

I used to be indecisive, now I'm not sure.
