Efika is broken because of this:

ohci-ppc-of.c...
	is_bigendian =
		of_device_is_compatible(dn, "ohci-bigendian") ||
		of_device_is_compatible(dn, "ohci-be");

Efika doesn't have either of those in it's compatible string.

This doesn't look to me like a very reliable way to determine bigendian.


My hardware may not be working because I've broken it. Time to call in
the hardware engineers.
