if I understood it correctly the following functions are called in this
order:

* prom_init() # arch/sparc/kernel/head.S
[...]
* create_node() # arch/sparc/kernel/prom.c
* build_prop_list() # arch/sparc/kernel/prom.c
* build_one_prop() # arch/sparc/kernel/prom.c
* prom_nextprop() # arch/sparc/prom/tree.c
* __prom_nextprop() # arch/sparc/prom/tree.c
* prom_nodeops->no_nextprop() # PROM

And this loops while getting the attributes/properties of the /aliases
node.

Markus
