2016-11-17google/gru: Move to one CA training patternDerek Basehore
This changes memory to only do CA training with one pattern, 0xfffff/0x00000 and to also make sure CA training waits for all of the captures during training.

2016-10-07google/gru: set W2W_DIFFCS_DLY to 5Lin Huang
PHY_PER_CS_TRAINING is being enabled when DDR frequency >= 666. For per cs training, the controller should consider the PHY delay line switch time and there should be more cycles to switch the delay line, so update the W2W_DIFFCS_DLY_ value from 0x1 to 0x5.

2016-08-27gru: Make SDRAM parameters individual struct files in CBFSJulius Werner
This patch changes Gru SDRAM parameters from structures that just get compiled into the romstage to individual CBFS files. This allows us to only load the parameter set we need for the board we're booting from flash, which reduces our boot time and the SRAM memory footprint required to hold the romstage. TEST=Booted Kevin.
