Driver for the CompactFlash slot on the PA Semi Electra eval board. It's a simple device sitting on localbus, with interrupts and detect/voltage control over GPIO. The driver is implemented as an of_platform driver, and adds localbus as a bus being probed by the of_platform framework.

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: 16 bit PCMCIA and 32 bit
|
|
CardBus cards.
|
|
|
|
To compile this driver as modules, choose M here: the
|
|
module will be called pcmcia_core.

Say Y here to enable PCMCIA subsystem debugging. You
|
|
will need to choose the debugging level either via the
|
|
kernel command line, or module options depending whether
|
|
you build the PCMCIA as modules.
|
|
|
|
The kernel command line options are:
|
|
pcmcia_core.pc_debug=N
|
|
pcmcia.pc_debug=N
|
|
sa11xx_core.pc_debug=N
|
|
|

The module option is called pc_debug=N
|

In all the above examples, N is the debugging verbosity

level.

This option enables support for 16-bit PCMCIA cards. Most older

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 in
|
|
most cases. (see the file <file:Documentation/Changes> for
|
|
location and details).

Some PCMCIA cards require an updated Card Information Structure (CIS)

and your userspace is arranged correctly, this will be loaded
|

automatically using the in-kernel firmware loader and the hotplug

subsystem, instead of relying on cardmgr from pcmcia-cs to do so.

If you say Y here, the deprecated ioctl interface to the PCMCIA

You should use the new pcmciautils package instead (see

CardBus is a bus mastering architecture for PC-cards, which allows
|
|
for 32 bit PC-cards (the original PCMCIA standard specifies only
|
|
a 16 bit wide bus). Many newer PC-cards are actually CardBus cards.
|
|
|
|
To use 32 bit PC-cards, you also need a CardBus compatible host
|
|
bridge. Virtually all modern PCMCIA bridges do this, and most of
|
|
them are "yenta-compatible", so say Y or M there, too.

If unsure, say Y.
