of_lookup_stdout() is useful for figuring out what device to use as output
for early boot progress messages. It returns the node pointed to by the
linux,stdout-path property in the chosen node.

On sparc platforms this is obtained differently. We obtain the 32-bit
instance value of "/chosen/stdout" and convert that into a prom device
node path using "instance-to-path".
How about if I modify it to try both methods?
The sparc method however cannot be used on powerpc because it requires
a call to OF to do the "live" conversion (ie, instance-to-path). In
fact, our /chosen/linux,stdout-path is just a cached result of that
conversion done during boot.
