From ee0263cc2e7d774655bba6a6750a06099a3cebf0 Mon Sep 17 00:00:00 2001 From: Graf Yang Date: Wed, 20 May 2009 06:06:15 +0000 Subject: [PATCH] Blackfin: BF518F-EZBRD: handle required portmuxing of async pins The two high address lines on the BF51x are not dedicated which means we need to handle them like any other peripheral pin if we want to access the upper 2MB of parallel flash.
