Pcmcia driver on Mips r39xx.

[Green]

Hi all,   I want to port pcmcia driver to my MIPS box. How could I begin?   I find that there is a line in the /init/main.c such like the following:   #ifdef CONFIG_PCMCIA  init_pcmcia_ds();  /* Do this last */ #endif   The init_pcmcia_ds() function is implemented at /drivers/pcmcia/ds.c. Should I add a CONFIG_PCMCIA label to the .config file and enable this config ?   Which file should I trace and modify?   Any reply is appreciated.   Best regards, Green
