  >  Finally (!?) get to the bottom of the mysterious G3 boot-time panics.
  >  After a number of tests using nop's to change the alignment, it was
  >  confirmed that the mtibat instructions should be cache-aligned.
  >  FreeScale app note AN2540 indicates that the isync before and after
  >  the mtdbat is the right thing to do, but sync/isync isn't required
  >  before the mtibat so it has been removed.

  >  Fix by using a ".balign 32" to pull the code in question to the correct
