Re: [PATCH] PCI serial card support

[n0ano]

Bad news, I heard back from the two people who wrote the PCI serial
code for Linux (Russell King & Ted Tso) and they both agree that,
no matter how the ambiguity got into the Linux source files, their
intent was that the code was GPL v2 only.

That being the case, we can't use the code and I don't want to try
and re-write it from scratch so we're back to having the user manually
specify the I/O port address but at least I can create a PCI ID table
to map the base baud.
