Subject: [PATCH] powerpc: Fix machine detection in prom_init.c

From: Michael Ellerman <[email-masked]>
Date: Wed, 05 Apr 2006 18:18:25 +0200

In e8222502ee6157e2713da9e0792c21f4ad458d50 the detection of machine types
in prom_init broke for some machines. We should be checking /device_type
instead of /model. This should make Power3 and Power4 boot again. Haven't
been able to test this.
