(My system is a MPC860 Processor Card, plus a custom made PCB to provide a PCMCIA interface, now the latest progress is I can use PCMCIA WLAN cards in this system without any problem. But my main target is use a PCMCIA Bluetooth card ... ) I have noticed when I load up the "serial.o", function "rs_init" must be executed, inside this function call, a function "autoconfig" will be called. My problem is due to this "autoconfig", it will try to parse a standard uart to determine what is its model. But my case is my standard uart is a PCMCIA Bluetooth Card. I can simply comment out the function "rs_init" to let the "serial.o" do not run this function. But later when I load the module "serial_cs", many problems happened. (seems "rs_init" will initialize other things that I have not done ...) Since "serial_cs" (the pcmcia uart driver) needs two function calls in "serial.o" (they are: resgister_serial() and unregister_serial() ), so I really need load up "serial.o" before I can load up "serial_cs.o" So my problem is, how can I setup such driver in MPC860 environment with a PCMCIA ?
