Subject: [PATCH] 8250_pci: add support for MCS9865 / SYBA 6x Serial Port
Card
This patch is heavily based on an earlier patch found on the linux-serial
mailing list [1], written by Darius Augulis.
The previous incarnation of this patch only supported a 2x serial port
card. I have added support for my SYBA 6x serial port card, and tested on
x86.

According to MAINTAINERS the 8250/16550 support currently lacks a
maintainer. The earlier incarnation of this patch was posted all the way
back in August.
If necessary, I can post an incremental patch from the Darius' earlier
patch. It would be great if someone could pick it up. I hate when new
hardware doesn't work, especially something as simple as this.
