From 671ee7f0ce62e4b991b47fcf1c161c3f710dabbc Mon Sep 17 00:00:00 2001 From: Liu Gang-B34182 Date: Thu, 25 Aug 2011 15:59:25 -0700 Subject: arch/powerpc/sysdev/fsl_rio.c: correct IECSR register clear value This bug causes the IECSR register clear failure. In this case, the RETE (retry error threshold exceeded) interrupt will be generated and cannot be cleared. So the related ISR may be called persistently. The RETE bit in IECSR is cleared by writing a 1 to it.

This breaks graphics on those machines among others. This fixes it using a quirk which copies the node pointer from the host bridge for the root complex, which makes the generic code work for the children afterward.
