This is a direct import of U-Boot DDR initialization code from git tree id a71d45d706a5b51c348160163b6c159632273fed. It is for Freescale mpc8xxx CPUs such as the mpc8544, P2020. Memory controller initialisation is based on data retrieved from a Serial Presence Detect (SPD) eeprom for DDR1/DDR2 and DDR3 memory. These patches are needed for the GEIP DA923RC board initialisation which will be submitted shortly.
