From 0044c42e94ecc258728190919b4619508fb83089 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Thu, 16 Aug 2012 17:55:41 +0000 Subject: Consolidate bootcount code into drivers/bootcount This patch moves all bootcount implementations into a common directory: drivers/bootcount. The generic bootcount driver is now usable not only by powerpc platforms, but others as well.
