Subject: [U-Boot] [PATCH 4/8] mpc512x: optionally configure DIU, LPC and NFC deviders
Date: Fri,  8 Feb 2013 11:03:46 +0100	[thread overview]
Message-ID: <1360317830-28525-5-git-send-email-agust@denx.de> (raw)
In-Reply-To: <1360317830-28525-1-git-send-email-agust@denx.de>

If a board config file defines DIU, LPC and NFC deviders,
configure them in the SCFR1 register.
