Which version of PPCBoot? The official releases (1.1.5)  should  work
just fine; they do so on several tested systems.

If you're using the top of tree on the CVS server (i. e. the  version
which includes the "Grand Unifying I2C interface patch") you may have
to  adjust a couple of things; this is not that well tested / working
yet.

I wonder why you use the CPM code at all.  I  always  found  it  much
easier to use CONFIG_SOFT_I2C ...
