From 10a5ecd03f9f5c374f954cf50a4f85d73f8ce338 Mon Sep 17 00:00:00 2001 From: Graf Yang Date: Wed, 1 Jul 2009 04:08:01 +0000 Subject: [PATCH] Blackfin: update handling of anomaly 364 (wrong rev id in BF527-0.1) This anomaly only applies to the BF527-0.1, not the BF526-0.1, and not any other revision of the BF527. So make sure we don't go returning 0xffff for other cases.
