Subject: [U-Boot-Users] [PATCH] mpc83xx: Update DIMM data bus width test to support 40-bit width
Date: Thu, 10 Apr 2008 09:35:06 -0500 [thread overview]
Message-ID: <1207838106.6999.2.camel@al08linux99> (raw)
32-bit wide ECC memory modules report 40-bit width.
Changed the DIMM data bus width test to 'less than 64' instead of 'equal 32'.
