Subject: [U-Boot] [PATCH 1/2] drivers/net/at91_emac.c: increase timeout for autonegotiation
Date: Thu,  7 Oct 2010 09:44:46 +0200	[thread overview]
Message-ID: <1286437487-10501-2-git-send-email-andreas.devel@googlemail.com> (raw)
In-Reply-To: <1286437487-10501-1-git-send-email-andreas.devel@googlemail.com>

This patch increases timeout for autonegotiation from 1 second to 3 seconds.
Some boards (e.g. at91rm9200ek) did not negotiate within 1 second.
