From 490e5730c674b20d708b783a2c5ffd7208f83873 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Sat, 31 Mar 2007 08:47:34 +0200 Subject: ppc4xx: Fix "bootstrap" command for Katmai board The board specific "bootstrap" command is now fixed and can be used for the AMCC Katmai board to configure different CPU/PLB/OPB frequencies.
