Subject: [U-Boot] [PATCH] am335x: disable internal delay for RGMII mode
Date: Mon, 26 Nov 2012 14:30:42 +0100	[thread overview]
Message-ID: <1353936642-28342-1-git-send-email-yegorslists@googlemail.com> (raw)

From: Yegor Yefremov <yegorslists@googlemail.com>

According to errata the AM335x device does not support internal delay
mode, so RGMII1_IDMODE and RGMII2_IDMODE must be set to 1.
