[PATCH v7 0/4] Add APNE PCMCIA 100 Mbit support

[Michael Schmitz <schmitzmic@gmail.com>]

Revisit support for the 100 Mbit APNE PCMCIA card variants, again.

Add a new ISA type for these cards, and switch to that type
from the APNE probe code in case 16 bit IO support is noted
the PCMCIA config table data. A module parameter or kernel
can be used to enable 16 bit IO as a fallback option.
Support for the 16 bit 10/100 Mbit cards is now included by
default.

The first two patches enable the use of core PCMCIA code to
parse config table entries. The remaining two patches add 16
bit IO support to the m68k low-level IO access code, and switch
the APNE driver to use 16 bit IO on cards that support it (the
100 Mbit cards).

I'm in two minds about enabling CONFIG_PCMCIA - the alternative
is to duplicate the cftable parser in amiga/pcmcia.c (which
has been tested and works just as well). Feedback welcome.

Tested by Alex on a 100 Mbit card. Not yet tested on 10 Mbit
cards - if any of those also have the 16 bit IO feature set
in their config table, this patch series would break on those
cards. 

Note that only patch 4 has been sent to netdev. Please CC
linux-m68k when providing comments.

Cheers,
