I'd love to present a patch.
Could you please give me a pointer where to find information about the
values of

k = (immr << 16) | *((ushort *) & immap->im_cpm.cp_dparam[0xB0]);

?
I couldn't find some.

Is it possible to find out if it's a 855, 857 or 860 at runtime?
So that we don't have to rely on DEFINES?

FAIK MPC855T and MPC857T are basicly the same. So could put both on my
board without actually changing the firmware.
Would be nice if u-boot could figure out which one is actually present.

Thanks,

Steven
