EST SBC8260

[Louis Krigovski]

I found few more things:

Once its stuck I can see CPU spining on exception 800 (Floating Point
Unavailable) which calls load_up_fpu. Then load_up_fpu in turn
enables FPU bit in msr and executes lfd     fr0,THREAD_FPSCR-4(r5)
which in turns generates trap 800 and again calls load_up_fpu.
  So I am spining in those 2 functions. Any idea how to approach finding
what is causing it. According to MontaVista manual thing should just boot
up.
