Before, we calculate the pwm duties for cpu cores and centerlogic by
hand, adding pwm_regulator.c to handle this. The default pwm design
min/max voltage may be different between revs.
With the pwm regulator, this patch changes the little cpu frequency from
600M to 1512M, and raises CPU voltage to 1.2V correspondingly.
This also means we decide to drop the ES1 because it may fail to
bootup with 1.5G ~ 1.2v.

The romstage.c is more board related than soc specific, like
setting the pwm regulators, so moving it to mainboard/gru.

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.

TEST=the device now reboots when it needs to switch between different

The Board ID on the Gru family of boards is determined by reading the
voltage from a resistor divider, each hardware revision is supposed to
have a unique resistor ratio, which allows to distinctly tell between
different Board ID.
While the long time approach to mapping resistor ratios (and voltages)
into Board ID remains under discussion, we know for sure the values
for Proto 1 and Proto 2. Let's just use them for now.
Since Board ID can be queried multiple times during boot, ideally it
should be read once and placed in the coreboot table to be available
to all coreboot stages. For now we just cache it so that at least
during the same stage the ADC has to run only once.
BRANCH=None
BUG=chrome-os-partner:51537
TEST=verified that the voltage reading on Proto 1 is as expected, and
Board ID 0 is reported.

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.

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)

Most things still need to be filled in, but this will allow
us to build boards which use this SOC.
[pg: separated out from the combined commit that added both SoC and
board. Added board_info.txt that will be added downstream, too.]
