spd_decode command is used for decoding and printing in human-readable format the information found in memory module SPD EEPROMs. There is the decode-dimms program from i2c-tools linux package (see http://www.lm-sensors.org/wiki/I2CTools) just for the same purpose. Though spd_decode source code is based on decode-dimms perl code there is a difference. Signed-off-by: Alexander Smirnov <alllecs@yandex.ru> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
