Not sure you want to be using resources as the basic currency, nor do you want your generic code doing the request_region stuff. That was a nasty mistake we made in the IDE code. Maybe the platform code should do that bit, but the generic stuff not - in the PCI case the caller will have done pci_request_* itself and chances are several of the resources are the same pci device resource and different offsets so doing request_resource on them will blow up. Concept looks good Alan
