Subject: [PATCH 5/9 v2] powerpc: mv64x60: remove device tree absolute path references

From: Dale Farnsworth <[email-masked]>
Date: Mon, 7 Apr 2008 11:50:54 -0700

From: Dale Farnsworth <[email-masked]>

Replace several device node absolute path lookups in the mv64x60
bootwrapper code with lookups by compatible or device_type
properties.
