From a1c4864ab0e1b98d82afa2438e54dc61ccad78cf Mon Sep 17 00:00:00 2001 From: Peter Tyser Date: Tue, 14 Sep 2010 19:13:51 -0500 Subject: [PATCH] powerpc: Zero out board info struct on bootup This puts the board info struct in a known state and allows the removal of other code which initialized board info fields to 0.
