Any chance you could cleanup the ifdef mess a little? e.g. adding a new
file for each platform and proper abstractions in the main source file.

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.

[PATCH 2.6.12-rc5-mm2] m32r: m32r_cfc.c build fix

[Hirokazu Takata]

I made a patch to fix a build error of m32r_cfc.c in 2.6.12-rc5-mm2 kernel.
This patch selects CONFIG_NONSTATIC for M32R PCMCIA/CF drivers.
