/config/ = "northbridge/amd/geodelx"; Then the file northbridge/amd/geodelx/dts is read in and processed. Magic(TM) appends the name "/dts" to the path. This hack is fine with chips that only do one thing. But some (all) northbridge parts play several roles: APIC cluster, PCI domain device, and PCI device. The result is a need for more than one dts, since there are three possible devices, with three types of IDs, and so on. To keep things sane, I am proposing to enable multiple dts files in a directory, names (e.g., nothing required here): domaindts pcidts apicdts (of course these names can be anything, this is just an example). This change will require a change to the dtc, since we can no longer assume just one dts file, and hence need a way to name these different files. The proposed change is very simple. We now require the full path name for the file, and eliminate the Magic(TM). So, /config/ = "northbridge/amd/geodelx/pcidts"; will open the pcidts file. /config/ = "northbridge/amd/geodelx/domaindts"; will open the domain dts. Maybe we should just call it domain and pci and apic? works for me. /config/ = "northbridge/amd/geodelx/domain"; /config/ = "northbridge/amd/geodelx/pcibridge"; /config/ = "northbridge/amd/geodelx/apic"; Changes: dtc.c: create a new function, fopenfile, that will only open a path if it really is a file. Modify dtc_open_file to use this function. fopenfile assumes "-" means stdin; should it, or should I move that assumption back to dtc_open_file? dtc.h: add prototypes dtc-parser.y: Given a config path, open the path. southbridge/amd/cs5536/cs5536.c: example of how C code changes Signed-off-by: Ronald G.
