Subject: [U-Boot] [PATCH 02/23] Add definitions for HDBCR registers
Date: Fri, 22 Mar 2013 10:15:10 -0700 [thread overview]
Message-ID: <1363972531-25641-2-git-send-email-yorksun@freescale.com> (raw)
In-Reply-To: <1363972531-25641-1-git-send-email-yorksun@freescale.com>
From: Andy Fleming <afleming@freescale.com>
Makes it a bit easier to see if we've properly set them. While
we're in there, modify the accesses to HDBCR0 and HDBCR1 to actually
use those definitions.
