49 | /* The following routines deal with the black magic of fully naming a |
50 | * node. | |
51 | * | |
52 | * Certain well known named nodes are just the simple name string. | |
53 | * | |
54 | * Actual devices have an address specifier appended to the base name | |
55 | * string, like this "foo@addr". The "addr" can be in any number of | |
56 | * formats, and the platform plus the type of the node determine the | |
57 | * format and how it is constructed. | |
58 | * | |
59 | * For children of the ROOT node, the naming convention is fixed and | |
60 | * determined by whether this is a sun4u or sun4v system. | |
61 | * | |
62 | * For children of other nodes, it is bus type specific. So | |
63 | * we walk up the tree until we discover a "device_type" property | |
64 | * we recognize and we go from there. | |
65 | * | |
66 | * As an example, the boot device on my workstation has a full path: | |
67 | * | |
68 | * /pci@1e,600000/ide@d/disk@0,0:c | |
