This ugly hack add support for Siemens MC45 PCMCIA GPRS card (which is
identical to Possio GCC, and which is offered by one of our local GPRS
providers). Card has unfortunate feature that after poweron oxcf950 chip
is fully powered and works, but attached MC45 modem is powered down :-(
There is a special sequence (which takes 1 sec :-( ) to poweron MC45 (and
after MC45 powers on, it takes more than 2 secs until firmware fully
boots...) which needs to be executed after all powerons.
I'm really not familiar with PCMCIA subsystem, so I have no idea whether I
should issue request_region() on rest of oxcf950 address range (0-7 is
UART, 8-F are special configuration registers), or how this should be
better integrated with PM system and so on - I just put it in same place
where another hack already lived...
Card uses 18.432MHz XTAL, so to get it to work you must add lines below to
the /etc/pcmcia/serial.opts.
case "$MANFID-$FUNCID-$PRODID_1-$PRODID_2-$PRODID_3-$PRODID_4" in
'030c,0003-2-GPRS-CARD--')
SERIAL_OPTS="baud_base 1152000"

Instead of the two status values struct pcmcia_device->p_state and state,
use descriptive bitfields. Most value-checking in drivers was invalid, as
the core now only calls the ->remove() (a.k.a. detach) function in case the
attachement _and_ configuration was successful.

Most of the driver initialization isn't done in the .probe function, but in
the internal _config() functions. Make them return a value, so that .probe
can properly report whether the probing of the device succeeded or not.

dev_link_t * and client_handle_t both mean struct pcmcai_device * by now.
Therefore, remove all such indirections.

Embed dev_link_t into struct pcmcia_device(), as they basically address the
same entity. The actual contents of dev_link_t will be cleaned up step by step.

As we do not allow setting Vcc in the pcmcia core, and Vpp1 and
Vpp2 can only be set to the same value, a lot of code can be
streamlined.

In all but one case, the suspend and resume functions of PCMCIA drivers
contain mostly of calls to pcmcia_release_configuration() and
pcmcia_request_configuration(). Therefore, move this code out of the
drivers and into the core.

pcmcia_disable_device(struct pcmcia_device *p_dev) performs the necessary
cleanups upon device or driver removal: it calls the appropriate
pcmcia_release_* functions, and can replace (most) of the current drivers'
_release() functions.

Unify the EVENT_CARD_INSERTION and "attach" callbacks to one unified
probe() callback. As all in-kernel drivers are changed to this new
callback, there will be no temporary backwards-compatibility. Inside a
probe() function, each driver _must_ set struct pcmcia_device
*p_dev->instance and instance->handle correctly.
With these patches, the basic driver interface for 16-bit PCMCIA drivers
now has the classic four callbacks known also from other buses:
int (*probe) (struct pcmcia_device *dev);
void (*remove) (struct pcmcia_device *dev);
int (*suspend) (struct pcmcia_device *dev);
int (*resume) (struct pcmcia_device *dev);

The linked list of devices managed by each PCMCIA driver is, in very most
cases, unused. Therefore, remove it from many drivers.

Unify the "detach" and REMOVAL_EVENT handlers to one "remove" function.
Old functionality is preserved, for the moment.

Move the suspend and resume methods out of the event handler, and into
special functions. Also use these functions for pre- and post-reset, as
almost all drivers already do, and the remaining ones can easily be
converted.

serial_cs's vendor/device identification got broken by Yum Rayan's change
'[PATCH] serial_cs: Reduce stack usage in serial_event()' - it changed buf
type from u_short* to char*, breaking device manufacturer & card number
retrieval. Due to this my modem stopped from being recognized as special
case.
Code will work much better if we'll rely on first_tuple's parser instead of
doing parse ourselves. Code also looks simpler after change.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
