Subject: [patch 2/4] 4xx: Fix timebase clock selection on Walnut

From: Josh Boyer <[email-masked]>
Date: Fri, 19 Oct 2007 09:53:10 -0500

The current bootwrapper fails to set the timebase clock to the CPU clock
which causes the time to increment incorrectly.  This fixes it by using the
correct #define for the CPC0_CR1 register.
