Subject: [U-Boot] [PATCH 2/3] netspace_v2: enable I2C EEPROM support
Date: Mon, 31 Oct 2011 14:58:35 +0100	[thread overview]
Message-ID: <1320069516-2105-3-git-send-email-simon@sequanux.org> (raw)
In-Reply-To: <1320069516-2105-1-git-send-email-simon@sequanux.org>

From: Simon Guinot <simon.guinot@sequanux.org>

An I2C EEPROM HT24LC04 (512B) is available on the netspace_v2 board
(and parents). This EEPROM hold data such as Ethernet MAC addresses
and power flags.
