Not really. ;)

Sorry, I'm wasting your time! I forgot another debugging modification of me.
A "for (;;)" at the end of pmap_bootstrap()!

Now I'm sure the source is clean an updated again.

The only remaining problem was that it cannot map ISA IO. The call caused
the same crash as seen in Jochen's post.

As the Efika has no ISA IO area, everything is included in the 5200B SoC, I
have just disabled the call and reached askroot:

How can we determine that we have to map ISA IO or not? The Pegasos, on the
other hand, might need it. Or maybe the Efika doesn't fit into ofppc at all,
and should go into evbppc?

To do:
- bootpath is missing (easy to fix)
- ofwpci is not detected (SmartFirmware shows: /pci@80000000)
- The PIC type is unknown (only 8259 and openpic supported)

I guess the last point will be the biggest task. There should be a new
directory in sys/arch/powerpc, called mpc52xx, or similar, which will
contain all the builtin 52xx functions.
