From fe7cca715c69f66efdc9c64462b0fd0a445331a5 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Wed, 19 May 2010 11:13:24 +0200 Subject: ppc4xx: Enable booting with Option E on 460EX/EXr/GT This patch enables booting with option E on the PPC460EX/EXr/GT. When booting with Option E, the PLL is in bypass, CPR0_PLLC[ENG]=0. The Software Boot Configuration Procedure is needed to engage the PLL and perform a chip reset.
