From 501c098a1f2cdaa930cb1a7166d3724467890a64 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Wed, 1 Jul 2015 13:28:39 +0200 Subject: arm: mvebu: Disable MBUS error propagation Accessing MBUS windows not backed-up by e.g. PCIe devices will hang the SoC. Disable MBUS error propagation back to CPU allows to read 0xffffffff instead of hanging the SoC.
