Subject: siemens: update DDR3 parameters for dxr2
X-Git-Tag: v2014.07-rc2~9^2~4^2~13
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=823b2c4ce4b54b658b45055bbc4c79f15789d48c;hp=9fc2ed40cd32cbb488e7a765e393e6b7ff21c1bc;p=karo-tx-uboot.git

siemens: update DDR3 parameters for dxr2

* add parameters for factory and print them at start up to
   facilitate control of right DDR3 settings in EEPROM.

 * cosmetic changes in a couple of printfs
