From e523f723d69cde44e10116d7f49b277da0c6702c Mon Sep 17 00:00:00 2001 From: Nathan Lynch Date: Wed, 10 Dec 2008 14:46:04 +0000 Subject: powerpc: Add of_find_next_cache_node() We have more than one piece of code that looks up cache nodes manually using the "l2-cache" property. Add a common helper routine which does this and handles ePAPR's "next-level-cache" property as well as powermac.
