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.
