[PATCH] ppc32: Dump error status for both PLB segments on 440SP
The PowerPC 440SP SoC has two Processor Local Bus (PLB) segments (a
high-throughput segment and a low-latency segment). Fix our PLB register
definitions to cope with this, and add code to dump the status of both
segments when a machine check occurs.
