This is aim64, a clone of macppc (just 64 bit). Here is what the arch hierarchy
looks like:
socppc macppc aim64 power
\ / \ /
\ / (architectures) \ /
\ / \ /
powerpc powerpc64
\ /
\ /
\ /
\ /
/usr/src/sys common kernel
As you can see aim64 is based on powerpc64. power is not even on the radar
yet. But people have already given support in hardware donations.
aim64 focuses on the PowerPC 970 CPU which is Macintosh PowerMac G5. Any
other computer would have to be in it's own branch (Sony PS3 perhaps?)
