PCMCIA Modem/Serial Cards and MPC8xx?

[Magnus Damm]

I don't know how things are today, but there was a collision between
the mpc8xx-uart code and the standard "pc" uart-code once upon a time.

I think the mpc8xx-uart code used the same struct as the other uart code,
but overloaded some values... But that was Linux-2.2.x, things have
probably changed - I hope... =)
