From f16295e7e7f2a2a15876f570f10d6dc8f1f36ab8 Mon Sep 17 00:00:00 2001 From: Robin Getz Date: Fri, 3 Aug 2007 18:07:17 +0800 Subject: Blackfin arch: Fix CCLK and SCLK checks Fix CCLK and SCLK checks, combine all arch checks into one file for maintance. Checkins that remove more lines than they add are always good.
