interfacing PXA255 with peripherals

hi,

                   iam working on project which requires both ehternet
controller and can controller, to be intefaced to the PXA255
processor.

                          and i thought of this proceedure for
interfacing.

1. memory map the can controller and ethernet controller to the pxa255
through using chip select signals of static memory or VLIO.

2. memory decoding to be implemented in order to select the right
controller.

                                   is that the right way to implement
interfacing of both controllers to the pxa255.

                                   does we require pcmcia controller
to implement pcmcia socket? i think pcmcia controller is in built in
processor

                                 please , provide me  valuable
suggesstions .

thanks in advance,

with regards,
