Hmmm...
ppc64 head.S and startup looks quite fun. After jumping through a few
hoops you eventually end up in prom_init and start setting up the OF
device-tree (btw it looks like at least one call to prom_panic doesn't
relocate the string it wants to print to real memory - is this what
the comments are referring to out of sheer interest?). I am assuming
that you always expect to see an Open Firmware on ppc64 and simply use
bi_recs to pass accross additional information from the bootloader,
but I've only had a cursory look on the train on the way home from
work this evening so please be gentle.
I'll give this a go through over the weekend and figure out how to get
this hooked in to the ppc32 tree.
Jon.
