87914c3169 The ARRAY_SIZE macro is convenient, yet mostly unused. Switch lots of
code to use it. That makes the code more readable and also less
error-prone.

e1ef6d2dc8 This change adds some debug prints, and a comment warning to dts on cs5536.
Most importantly it fixes a simple programming error which made it so most of
the sets on the USB were not doing anything. The bug is also in V2.

With this fix, the DBE62 USB ports all work!

If someone clones the fix to V2, it will also fix V2. Or, we can just convince
you to move forward to V3 :-)

b2e1002d9d With this set of changes dbe62 gets to a FILO prompt.
Set manual settings for dbe62 PLL; the auto settings are giving
slightly wrong values

Add call to dumplxmsr in dbe62 initram main()

Change dumplxmsr to void parameter

Add dumplxmsrs function to geodelx raminit support code

Correct spelling of CAS.

The big one: set spd variables correctly.

The not so big one: there is a bug in com2 enable I don't understand.
For now comment out two offending lines. The cs5536 debug prints
should be reduced later.

Change fuctory to factory. It's funny but confusing.
This patch also takes into account carl-daniel and uwe's comments.

718dab6ba5 This is a cumulative set of fixes for LX800 boards. These are all tested on ALIX 1C and DBE62.
This includes:
 - the working power button patch.
 - onchipuart2 for very early startup -- this will be replaced with a better mechanism soon.
 - dts mod for powerbutton on cs5536
 - dbe62 dts fix for COM1 setup
 - ram check call in dbe62 initram.c
 - Carl-Daniel's fix to detect incorrect access to spd variables.
 - more debug prints in geodelx northbridge support code.

 This is cumulative since we're lagging on acks a bit and it's hard to keep this
 stuff all seperated out since it involves a common set of files. I'd like to get
 it acked and in tree today if possible. It's a very small set of lines changed so please
 forgive me for the cumulative nature.

 Thanks

f7ad196c0a This started out as a trivial change and turned into a big change. This
code boots and works on qemu and
alix1c. It represents a huge change and a huge improvement. There are a
few fixes left to do, which 
will come once this is in. 

This change started out easy: get the device IDs OUT of the the dts, and
into one place. We
decided the device IDs should be in the constructors ONLY. To make a
long story short, that just did 
not work out, and it revealed a flaw in the design. The result? 

- no more ids in the various dts files. 
- the constructor struct is gone -- one less struct, nobody liked the
  name anyway
- the device_operations struct now includes the device id.
- constructor property no longer used; use device_operations instead. 
- lpc replaced with ioport

All the changes below stem from this "simple" change. 

I am finding this new structure much easier to work with. I hope we're
done
on this for real, however!

TODO: 
1. Change limitation in dtc that makes it hard to use hex in pci@
notation. 

Now for the bad news. Sometime today, interrupts or io or something
stopped working between r596 and r602 -- but I did no commits at
that point. So something has gone wrong, but I don't think it's this
stuff.

I did try a build of HEAD, and it fails really, really badly. Much
more badly than this fails, so I think this commit is only going
to improve things. It does work fine on qemu, fails on alix1c, 
so I suspect one of today's "clean up commits" broke something.

6ac804f594 This is a subtle error. An operations struct, to work as a constructor, must initialize
the .constructor struct member. 

This error is so subtle that we might consider changing the device code; or at least 
working on the documentation to make it more clear. The key question: do we ever want 
an operations struct that can NOT operate as a device constructor? When this code was 
designed over a year ago, it seemed that we might; now, it is not so certain.

643d952c5b In the current version of dtc, if one has the line:
/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.
