Subject: [PATCH 5/8 v3] [POWERPC] prpmc2800: clean up dts properties

From: Dale Farnsworth <[email-masked]>
Date: Mon, 7 Apr 2008 15:10:34 -0700

From: Mark A. Greer <[email-masked]>

Remove several unused (or software config only) properties.
Rename marvel node to "system-controller".  Also, rename the
"block-index" property to "cell-index" to conform to current
practice.
