Subject: [U-Boot] [PATCH 4/7] powerpc/mpc8xxx: check SPD length before using part number
Date: Fri, 27 May 2011 07:25:50 +0800	[thread overview]
Message-ID: <1306452353-11611-4-git-send-email-yorksun@freescale.com> (raw)
In-Reply-To: <1306452353-11611-1-git-send-email-yorksun@freescale.com>

From: york <yorksun@freescale.com>

Only use DDR DIMM part number if SPD has valid length, to prevent from
display garbage in case SPD doesn't cover these fields.
