pcmcia: remove unused pxa/sa1100 drivers
A number of boards got removed, so this code is now orphaned. Cc: Dominik Brodowski <linux@dominikbrodowski.net> Acked-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

* BadgePAD 4 Details
|

*
|

* PCM Vcc:
|

*
|
||||
* PCM Vcc on BadgePAD 4 can be jumpered for 3v3 (short pins 1 and 3
|
||||
* on JP6) or 5v0 (short pins 3 and 5 on JP6).
|
||||
*
|
||||
* PCM Vpp:
|

*
|
||||
* PCM Vpp on BadgePAD 4 can be jumpered for 12v0 (short pins 4 and 6
|
||||
* on JP6) or tied to PCM Vcc (short pins 2 and 4 on JP6). N.B.,
|
||||
* 12v0 operation requires that the power supply actually supply 12v0
|
||||
* via pin 7 of JP7.
|
||||
*
|
||||
* CF Vcc:
|
||||
*
|
||||
* CF Vcc on BadgePAD 4 can be jumpered either for 3v3 (short pins 1
|
||||
* and 2 on JP10) or 5v0 (short pins 2 and 3 on JP10).
|
||||
*
|
||||
* Unfortunately there's no way programmatically to determine how a
|
||||
* given board is jumpered. This code assumes a default jumpering
|
||||
* as described below.
|
||||
*
|
||||
* If the defaults aren't correct, you may override them with a pcmv
|
||||
* setup argument: pcmv=<pcm vcc>,<pcm vpp>,<cf vcc>. The units are
|
||||
* tenths of volts; e.g. pcmv=33,120,50 indicates 3v3 PCM Vcc, 12v0
|
||||
* PCM Vpp, and 5v0 CF Vcc.
