The encoding of BSTOPRE is complex.  It is split into 3 subfields, and
spread over MCCR2 and MCCR4.  The discrepency seems to be due to
different assumptions about how the subfields are ordered in the
composite value.
The code in cpu/mpc824x/cpu_init.c extracts the pieces as
  ( BSTOPRE[6-9] || BSTOPRE[2-5] || BSTOPRE[0-1] )
Per Freescale technical support, these three fields are to be assembled as
  ( BSTOPRE[0-1] || BSTOPRE[2-5] || BSTOPRE[6-9] )
So what yould your proposed patch look like?
