2016-08-03google/gru: Add support for Gru rev1Julius Werner
This patch adds support for the Gru rev1 board. This board differs from rev0 by no longer relying on the I2C backlight booster and requiring the same ODT SDRAM settings as newer Kevin boards.

2016-07-28google/gru & kevin: Update DRAM configurationLin Huang
We need to enable DRAM ODT on kevin/gru board to improve the DRAM signal. Note, if the DRAM ODT is enabled and set to 120ohms, the sdram VREF need to adjust to 840mv. This patch also makes following changes: 1. For compatiblity with the old board, add the "sdram-lpddr3-hynix-4GB-666-no-odt.inc" and "sdram-lpddr3-hynix-4GB-800-no-odt.inc" files which do not enable sdram ODT. 2. Delete the 300MHz dram inc file. The 300MHz sdram config just reduced 666MHz to 300MHz based on the 666MHz config file, and it is not stable, so delete it. 3. Delete the 928MHz dram inc file, 928MHz sdram config still in debuging, delete it for now.

2016-06-24rockchip/rk3399: provide multiple SDRAM configurationsLin Huang
We want to be able to easily change SDRAM clock rate for debugging purposes. This patch adds configurations for 4 different clock rates. Same configs are used for all rk3399 boards at 200, 666 and 800 MHz. Kevin board does not run reliably at 666 MHz, an option for it is added to run at 300 MHz, this option is available to Kevin only. There is not much room left in the coreboot romstage section, this is why the config file for 928 MHz is being added with this patch but is not included in the code, one of the lower frequency options will have to be dropped for the higher frequency option to be added. BRANCH=none BUG=chrome-os-partner:54144 TEST=run "stressapptest -M 1024 -s 3600" and pass on both kevin and gru. Verified that on Kevin the firmware reports starting up SDRAM at 300 MHz and on Gru at 800 MHz.
