- ISA DMA is broken on IP28
- bus error handler improved to not issue bus errors for
 speculative accesses to CPU and GIO addresses. We now
 treat CSTAT_ADDR and GSTAT_TIME errors as non fatal, when
 they are issues via MC error interrupt. For real (non
 speculative) bus errors a DBE will be issued, which is
 lethal as before. Handling the issue this way gets rid
 of decoding instructions

Folded into the "[MIPS] IP28 support" patch for 2.6.28.


  Poor IP32 will have to wait couple of years? ;-)


Thanks,



  Ralf


WBR, Sergei
