[PATCH] pcmcia: add a config option for the PCMICA ioctl

Browse source 
Add a new config option to control the building of the PCMCIA IOCTL. Currently,
it is not yet made public, though the help text is there already.

Say Y here if you want to attach PCMCIA- or PC-cards to your Linux
computer. These are credit-card size devices such as network cards,
modems or hard drives often used with laptops computers. There are
actually two varieties of these cards: the older 16 bit PCMCIA cards
and the newer 32 bit CardBus cards.

PC-cards are such 16-bit PCMCIA cards, so unless you know you're
only using 32-bit CardBus cards, say Y or M here.
To use 16-bit PCMCIA cards, you will need supporting software from
David Hinds' pcmcia-cs package (see the file <file:Documentation/Changes>
for location). Please also read the PCMCIA-HOWTO, available from
<http://www.tldp.org/docs.html#howto>.

If you say Y here, the deprecated ioctl interface to the PCMCIA
subsystem will be built. It is needed by cardmgr and cardctl
(pcmcia-cs) to function properly.
If you do not use the new pcmciautils package, and have a
yenta, Cirrus PD6729, i82092, i82365 or tcic compatible bridge,
you need to say Y here to be able to use 16-bit PCMCIA cards.
