Re: powerpc_flash_init(), wtf!?

If the RAM and/or ROM sit on the SoC bus, the "ranges"
property in the SoC node should be able to translate
their addresses, yes.  You could opt for having the
memory controller a separate device node, as a sibling
of the "soc" node, if that agrees better with your
SoC architecture.  "It all depends".

But if the flash really is on an external bus controlled by a bus
controller on the SoC, it sounds like it should go under that bus
bridge.  In which case the SoC would need another range in its ranges
property.

Yeah, it all depends on the specific SoC device.
I don't know which one we're talking about here
so I can't give any more specific advice.
