Subject: [patch 03/10] Rename 44x bootwrapper

From: Josh Boyer <[email-masked]>
Date: Fri, 03 Aug 2007 11:09:03 -0500

Rename the 44x.c wrapper file to 4xx.c.  This will allow us to add common
functions in a single file that can be shared across all of 4xx.

Signed-off-by: Josh Boyer <[email-masked]>
