    powerpc/fsl-booke: Cleanup init/exception setup to be runtime · 105c31df
    Kumar Gala authored
    We currently have a few variants of fsl-booke processors (e500v1, e500v2,
    e500mc, and e200).  They all have minor differences that we had previously
    been handling via ifdefs.
    
    To move towards having this support the following changes have been made:
    
    * PID1, PID2 only exist on e500v1 & e500v2 and should not be accessed on
      e500mc or e200.  We use MMUCFG[NPIDS] to determine which case we are
      since we only touch PID1/2 in extremely early init code.
    
    * Not all IVORs exist on all the processors so introduce cpu_setup
      functions for each variant to setup the proper IVORs that are either
      unique or exist but have some variations between the processors
