+commit 787fa15860a57833e50bd30555079a9cd4e519b8
+Author: Wolfgang Denk <wd@pollux.denx.de>
+Date:	Wed Jan 10 01:28:39 2007 +0100
+
+    Fix auto_update for MCC200 board.
+
+    The invocation of do_auto_update() is moved to the end of the
+    misc_init_r() function, after the flash mappings have been
+    initialized. Please find attached a patch that implements that
+    change.
+
+    Also correct the decoding of the keypad status. With this update, the
+    key that will trigger the update is Column 2, Row 2.
