I make this changes:

Add in spr.h:

#define   SVR_MPC8548             0x8031
#define   SVR_MPC8548E            0x8039

ocpbus_probe():

         if (ver == SVR_MPC8572E || ver == SVR_MPC8572)
                 law_max = 12;
         else if (ver == SVR_MPC8548E || ver == SVR_MPC8548)
                 law_max = 10;
         else
                 law_max = 8;

cpu_reset():

         if (ver == SVR_MPC8572E || ver == SVR_MPC8572 || ver == SVR_MPC8548E || ver == SVR_MPC8548)
                 /* Systems with dedicated reset register */
                 ccsr_write4(OCP85XX_RSTCR, 2);
         else {

law_getmax():

         if (ver == SVR_MPC8572E || ver == SVR_MPC8572)
                 return (12);
         else if (ver == SVR_MPC8548E || ver == SVR_MPC8548)
                 return (10);
         else
                 return (8);

Hmm. With decr_config(0) kernel is booted, but with actual CCB clock 
533000000 kernel silently hang somethere in kdb_init() or "data storage 
interrupt" occured.

With decr_config(0) kernel boot look like this now:

setting up elf image... OK
jumping to kernel code
