I'm now in trouble with CF device detection at boot time in case of pccard_static_ops.
I guess it has a relationship with that CS_UNSUPPORTED_FUNCTION is returned by rsrc_mgr.c:pcmcia_adjust_resource_info() in !CONFIG_NONSTATIC. But I'm not sure...
So, I will show you the driver's status as following. I hope any comments if possible.
Thanks in advance.

Status of the M32R CF driver ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ configuration : status --------------------------------------- + -------- pccard_nonstatic_ops (CONFIG_NONSTATIC) : OK pccard_static_ops (!CONFIG_NONSTATIC) : NG
OK ... In NONSTATIC (CONFIG_NONSTATIC, pccard_nonstatic_ops) case, a CF disk/memory device can be probed and mounted normally. NG ... In STATIC (!CONFIG_NONSTATIC, pccard_static_ops) case, a CF disk/memory device can *not* be probed automatically now. But a CF device can be mounted after "pccardctl insert" command execution, and also a CF device insert event can be handled correctly.
