Jonathan Chen 0db7e66cdc Initial commit of NEWCARD cardbus side (that actually compiles and works)
Files:
	dev/cardbus/cardbus.c
	dev/cardbus/cardbusreg.h
	dev/cardbus/cardbusvar.h
	dev/cardbus/cardbus_cis.c
	dev/cardbus/cardbus_cis.h
	dev/pccbb/pccbb.c
	dev/pccbb/pccbbreg.h
	dev/pccbb/pccbbvar.h
	dev/pccbb/pccbb_if.m

This should support:
  - cardbus controllers:
    * TI 113X
    * TI 12XX
    * TI 14XX
    * Ricoh 47X
    * Ricoh 46X
    * ToPIC 95
    * ToPIC 97
    * ToPIC 100
    * Cirrus Logic CLPD683x
  - cardbus cards
    * 3c575BT
    * 3c575CT
    * Xircom X3201 (includes IBM, Xircom and, Intel cards)
    [ 3com support already in kernel, Xircom will be committed real soon now]

This doesn't work with 16bit pccards under NEWCARD.

Enable in your config by having "device pccbb" and "device cardbus".
(A "device pccard" will attach a pccard bus, but it means you system have
a high chance of panicing when a 16bit card is inserted)

It should be fairly simple to make a driver attach to cardbus under
NEWCARD -- simply add an entry for attaching to cardbus on a new
DRIVER_MODULE and add new device IDs as necessary.  You should also make
sure the card can be detached nicely without the interrupt routine doing
something weird, like going into an infinite loop.  Usually that should
entail adding an additional check when a pci register or the bus space is
read to check if it equals 0xffffffff.

Any problems, please let me know.
