Porting problems

[Dag Nygren]

Hi,

I am porting Linux to an unsupported (so far)
VME-board and have been banging my head into
the following problem for some time now,
nothing seems to help.....

Thought I would ask the wise men on the net for some
hints on where to look.

The board is hal PReP and half CHRP and I have been
struggling to get the boot to work.
At the moment it starts up using the VxWorks boot
and I then load Linux over the net and start it up.

The problem can be that the VxWorks monitor
inits something wrongly ?

Any hint welcome.

The processor is a PPC740

Boot log:

     -K (specified)
