Subject: [U-Boot] [PATCH 1/3] mx23: Operate DDR voltage supply at 2.5V
Date: Sun, 5 May 2013 22:52:54 -0300 [thread overview]
Message-ID: <1367805176-16156-1-git-send-email-festevam@gmail.com> (raw)
From: Fabio Estevam <fabio.estevam@freescale.com>
After the recent fixes in the mx23 DDR setup, it is safe to operate DDR voltage
at the recommended 2.5V voltage level again.
