count there is (for SCSI, adapt_refcnt) to 1 and call the appropriate
"delref" function afterwards to disable the controller. This is a bit
simpler.
In a couple of cases, just remove the state machine, because it wasn't
really necessary.
* Remove the "expected function" value. This was just causing problems with
multifunction cards. Differentiating the functions is better done by
checking the function type (which we now do in ep and sm).
* Add support for matching CIS strings. This necessitated changing the calling
pattern a little too.
Use this enhanced version rather than driver-specific versions that do the
same thing.
Also, remove the last vestiges of PCMCIA_STR_*.
XXX Note: This eliminates some register writes that were done in the "init"
routine during attach. If these are necessary, they need to do done somewhere
else, quite possibly the enable routine.
"While I'm here..."
All that grotesque code allegedly for the 88190 and 88790 is actually just
mapping the CCR and writing to it. So, enable the device normally and use
pcmcia_ccr_{read,write}() rather than doing this crap ourselves.
force it to 0 when a card is detached, possibly disabling the socket in the
process.
Add several new functions:
* pcmcia_config_alloc(pf, cfe)
Tries to allocate all the I/O and memory spaces in a config entry.
* pcmcia_config_free(pf)
Frees all the I/O and memory spaces for the active configuration.
* pcmcia_config_map(pf)
Maps all the allocated I/O and memory spaces for the active configuration.
* pcmcia_config_unmap(pf)
Unmaps all the allocated I/O and memory spaces for the active configuration.
And two higher-level functions:
* pcmcia_function_configure(pf, validator)
Tries to find a CIS config entry that it can allocate the spaces for. Each
entry is verified by calling the "validator" function -- which can also do
card- and driver-specific fixups. If successful, the regions are all mapped.
* pcmcia_function_unconfigure(pf)
Equivalent to calling both pcmcia_config_unmap() and pcmcia_config_free().
Most drivers are expected to use the latter two functions, which will greatly
reduce the amount of crufty code.
