As part of interfacing with OpenFirmware we need to access the device tree, nodes and instances. This is the main interface into OFW's support for most things.
With help from Mitch Bradley again, the document Luke sent and some time, I managed to implement a base for OFWDeviceNode.
mem := OFWDeviceNode findDevice: '/memory'
may be working, it answers an instace of OFWDeviceNode with the phandle set
however, if I then try
mem getPropLen: 'size'
to get the size of the property named 'size', SqueakNOS freezes (crashes probably).
So I think we may actually be running on the memory problem we (Luke) described in an earlier mail. Or otherwise, some problem derived from the primitive implementation... uhm, this gives me an idea to test what's going on... let's see.
