<DIV><FONT face=Arial size=2><SPAN class=908372911-07022007>I found a little
problem in cpu/mpc8xx/cpu_init.c in u-boot-1.2.0. There are some instructions to
reset br0 for MPC850 near line 120. This code is executed for all cpu. In my
opinion should be limited to MPC850 cpu because, after a few lines when br0 is
configured with CFG_BR0_PRELIM, debuggers (like BDI) receive a machine check
exception. It seems that resetting BR0 and setting it again causes some
debugging problems.</SPAN></FONT></DIV>
