Sparc also uses open firmware and shares some of the device-tree
handling code with powerpc in linux. Other operating systems on those
platforms also use it (AIX, Solaris, MacOS, ...)

I think the proposed new Xilinx microblaze architecture also uses it,
and at least on x86, the OLPC has an Open Firmware implementation though
it doesn't use the device-tree the way we do currently on powerpc and
sparc and has its own interface to the firmware.
