883f5cbdce rockchip/rk3399: sdram: also prepare the index1 configuration
To enable DDR Dynamic Voltage and Frequency Scaling (DVFS) we need to
train alternative configurations first, so do the training and store the
values.

df3321aa34 rockchip/rk3399: reset system if DDR init fails
We found sdram may fail in pctl_cfg(), so we check the status in this
function. If it exceeds 100ms still in this function, we will restart
the system. We also found there are rare chances DDR training fails,
so also restart system in that case.

5b1bb3d980 google/gru: Add USB 2.0 PHY tuning for Kevin PHY0 and PHY1
We found that Kevin board PHY0 and PHY1 eye-diagram margin
is not enough to make compliance test pass, and the PHY0 USB
SI is worse than PHY1, because of the higher PCB impedance.

For PHY0, we can't improve the eye-diagram by SW PHY tuning,
so we need to reduce the RBIAS resistance from 133 ohm to 115
ohm, it can help to increase the eye-height.

For PHY1, we can improve the eye-diagram by setting the max
pre-emphasis level.

And after the above change, the USB2 signal amplitude will
become larger at the test point near to SOC USB2 PHY, in order
to avoid mis-trigger the disconnect detection (650mV), we need
to disable pre-emphasize in eop state.

e06a1b895c google/gru: drive WLAN_MODULE_RST# low as early as possible
GPIO1_B3 (WLAN_MODULE_RST#) defaults as a pull-up input, but it is also
"pulled up" by 1.8V_WLAN. However, 1.8V_WLAN remains low for some time
during early boot. This leaves the signal floating somewhere in the
middle.

This has two potential issues:
(1) we're leaking some power for some (hopefully) short period of time
(2) we are possibly screwing with the Wifi power sequence; we aren't
    supposed to deassert PDn (i.e., MODULE_RST#) until all the rails
    have fully ramped for some period of time

Neither of the above issues are likely to be significant, but it is nice
to fix, I expect.

547a059b34 google/gru: Shrink RW_ELOG region to 4KB
Since there's currently a limitation in coreboot's code that prevents
more than 4KB to be used by the eventlog anyway, this patch shrinks the
available RW_ELOG area in the FMAP for Gru down to 4KB. This may prove
prudent later if we ever resolve that limitation, so that tools can rely
on the area in the FMAP being the same as the area actually used by the
read-only firmware code on these boards.

7f965891b6 rockchip/rk3399: Move big CPU cluster initialization into ramstage
This patch moves the big CPU cluster initialization on the RK3399 from

actually taking it out of reset ourselves... so there's no reason to do
this so early.

7feb86b26b google/gru: Ensure correct pull resistors for special-function pins
Several of the special function pins we're using in firmware have a
pre-assigned pull-up or pull-down on power-on reset. We don't want those
to interfere with any of the signaling we're trying to do on those pins,
so this patch disables them.

Also do some house-cleaning to group the bootblock code better, and
change the setup code for all SPI and I2C buses to first initialize the
controller and then mux the pins... I assume this might be a little
safer (in case the controller peripheral has some pins in a weird state
before it gets fully initialized, we don't want to mux it through too
early).

We did yet another small adjustment to the PWM regulator ranges for
Kevin rev6... this patch reflects that in code. Also rewrite code and
descriptions to indicate that these new ranges are not just for Kevin,
but also planned to be used on Gru rev2 and any future Gru derivatives
(which as I understand it is the plan, right?).

b6bf1ddb91 gru: Add watchdog reset support
This patch adds support to reboot the whole board after a hardware
watchdog reset, to avoid the usual TPM issues. Work 100% equivalent to
Veyron.

From my tests it looks like both SRAM and PMUSRAM get preserved across
warm reboots. I'm putting the WATCHDOG_TOMBSTONE into PMUSRAM since that
makes it easier to deal with in coreboot (PMUSRAM is currently not
mapped as cached, so we don't need to worry about flushing the results
back before reboot).

BRANCH=None
BUG=chrome-os-partner:56600
TEST='stop daisydog; cat > /dev/watchdog', press CTRL+D, wait 30
seconds. Confirm that system reboots correctly without entering recovery

61e6c4448c rockchip/rk3399: Add pwm_regulator.c for pwm then ramp boot up cpu
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.

This reverts commit 850e45f19f.

google_chromeec_init() is a weird function that can lead to confusing
behavior. I'm not sure how it's meant to work on the boards that use it,
but it causes problems on Kevin and other non-x86 boards have never used
it either. It doesn't really do anything anyway (the EC works fine
without an initial HELLO), so at best it's just a waste of time... let's
take it back out.

There's also no need to display the current time on every boot... other
boards don't do that and the eventlog already fills the same purpose.
Cut it out to avoid one extra host command overhead.

785ff1b7db rockchip/rk3399: Add code to neuter Type-C PHY for firmware USB
The Rockchip RK3399 integrates a USB Type-C PHY in charge of things like
SuperSpeed line muxing for rotated cable orientations in the SoC. While
fancy, this is very complicated and we don't want to implement support
for the whole thing in firmware. The USB Type-C standard has
intentionally been designed in a way that the USB 2.0 (HighSpeed) lines
always "just work" in any orientation (by just shorting different pins
in the connector together) so that simple use cases like ours can get
basic USB functionality without much hassle.

However, a semi-configured Type-C PHY can confuse USB 3.0 capable
devices into thinking we're actually supporting SuperSpeed, and fail at
that rather than establishing a reliable HighSpeed connection. This
patch sets enough bits in the Type-C PHY to electrically isolate the
SuperSpeed lines from the connector so that the connected device isn't
going to get any fancy ideas and reliably falls back to USB 2.0.

Also clean up the rest of the USB code while we're at it: avoid writing
a few bits that are already in the right state from their reset values
anyway, or reading values whose content we already know for this SoC.
Rename the USB controllers to the name actually used in the Rockchip
documentation (USB OTGx) rather than the name blindly copied from
Exynos code (USB DRDx).

BRANCH=None
BUG=chrome-os-partner:54621
TEST=Plug a USB 3.0 Patriot Memory stick into both ports in all

"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

de110ee07d google/gru: Change UART _Static_assert() condition to #if
_Static_assert() gets evaluated even when the code path it's in is
unreachable (e.g. inside an if (0) block). Unfortunately, Kconfigs that
depend on a disabled Kconfig are always 0, meaning that
CONFIG_CONSOLE_SERIAL_UART_ADDRESS on Gru cannot evaluate to UART2 when
CONFIG_CONSOLE_SERIAL (which it depends on) is disabled. Switch the
condition it is wrapped in to a preprocessor #if so that the
_Static_assert() is not evaluated when building without serial support.

BUG=None
TEST=Built and booted Kevin without serial

627c27bb92 rockchip/rk3399: provide multiple SDRAM configurations
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.
