/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.

- I left LB_TAG_ intact because they are used by the payloads
- file renames are still missing. see next commit
- some lb_ renames might be missing. feel free to provide patches.
