2016-05-18rockchip: rk3399: add tsadc driverShunqian Zheng
This patch configures clock for tsadc and then makes it in automatic mode to generate TSHUT when CPU temperature is higer than 120 degree Celsius. BRANCH=none BUG=chrome-os-partner:52382,chrome-os-partner:51537 TEST=Set a lower tshut threshold(45C), run coreboot and check that coreboot reboot again and again.

2016-05-09rockchip/rk3399: Set all 4 DVFS voltage rails to 1.1V @300kHzVadim Bendebury
Previous code had several problems: * It was only initting 3 of the 4 voltage rails hooked up to PWM regulators. * It was using a PWM frequency that was out of range. Apparently from testing 300kHz is best. * It was initting all rails to .9V. On my Kevin I needed 1.1V to make booting all 6 cores / rebooting reliable. With this fix both booting all 6 cores in the kernel is reliable (if we tell the kernel not to touch the PWM) and the "reboot" command from Linux userspace is also reliable (previously it crashed in coreboot). NOTES: * Setting all rails to the same voltage doesn't make a lot of sense. We should figure out what these should _actually_ be. Presumably the little CPU rail can be lower, at least. ...and we don't use the GPU in the BIOS so we should set that lower.

Add the sdram driver for rk3399. With this patch we can boot into depthcharge. This patch also include a config file for lpddr3-hynix-4GB that generated bases on its datasheet.

2016-05-09rockchip: rk3399: enable mmuLin Huang
This patch initialize MMU and config mmu ranges for rk3399. During the bootblock phase, mark the max dram size supported(4GiB) as device memory because the mmio space start at 0xF8000000, and _sram as secure memory. After ddr setup in romstage, remark whole dram as cached memory except the _dma_coherent range.

To avoid diverging too much on an actively developed code base, keep the changes to a separate commit that can be downstreamed more easily: - removed unused includes - gave kevin board a "Kevin" part number - marked RW_LEGACY as CBFS region (to follow up upstream changes) - moved romstage entry point to SoC code (instead of encouraging per-board copy pasta) Change-Id: Ief0c8db3c4af96fe2be2e2397d8874ad06fb6f1f Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: https://review.coreboot.org/14362 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>
