Patch from Richard Purdie This patch updates the PCMCIA pxa2xx_sharpsl driver to support multiple scoop devices by adding a scoop to pcmcia slot mapping structure. It adds platform support for poodle, is known to work on spitz (which is dual slot) and should also support collie with a minor amount of further work.
