From 20979584fe28e9e62a71aa92c5c5ad8074790de4 Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Fri, 24 Sep 2010 18:42:56 +0000 Subject: Automatically fetch bus information for mptable from the device tree, instead of using hardcoded values. If this changes behaviour, this is either - a bug in mptable_write_buses(), or - a bug in the old mptable or device config, that is they were inconsistent.
