From 41aace4fe81e3da52fa80b8380e5d2d084f77691 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Mon, 7 Nov 2005 00:58:12 -0800 Subject: [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.
