I had an offline discussion with Josh Cartwright about his concerns. He brought up a good point on w.r.t to the way FPGA Area (Bus) deals with things. Currently we only support complete status = "okay" vs "disabled" kind of overlays. If now you have say a UART in the FPGA that you don't want to go away and come back on reload, we don't have a good way of expressing this. Is there a good way to express non-mmio FPGA devices? I've been toying around with hacking up struct device to include a FPGA 'domain', and then, similar to power domains allow devices to register suspend() / resume() style callbacks (could call them pre_reload() or something like that ...) I haven't gotten around to think it through. At this point it's just an idea and I don't have real code to show. I realize the issue with that is we'd have to make changes to struct device.
