On older Grus, GPIO0_A2 was an audio voltage rail enable line. On
Scarlet, we instead moved the audio codec enable (previously on
GPIO1_A2) there. Unfortunately the code still had some hardcoded
leftovers that were overlooked in the initial port and make our speakers
smell weird.
This patch fixes the incorrect GPIO settings and adds the speaker enable
pin to the GPIOs passed through the coreboot table, so that depthcharge
doesn't have to keep its own definition of the pin which may go out of
sync.

RK3399 has a pin that can decide whether GPIO port 1 is driven with 1.8V
or 3.0V. We thought this mechanism was disabled by default, but it turns
out it wasn't. We want to use that pin as an output GPIO on Scarlet so
we need to reconfigure the respective SoC controls before we do that. It
seems that we also need to explicitly pinmux the pin away from that
special function (to normal GPIO) or weird things happen on some boards.

We've decided to move control for the 3.0V rail (technically 3.3V on
Scarlet, but who cares about millivolts) back to a GPIO on the AP for
Scarlet rev2. This patch adds the necessary code to enable it and make
ARM TF aware of its existence. Since the pin had previously not been
connected to anything, we shouldn't really need to guard this by board
ID... older Scarlets will just be twiddling an empty pin.

Split `i2c.h` into three pieces to ease reuse of the generic defi-
nitions. No code is changed.
* `i2c.h` - keeps the generic definitions
* `i2c_simple.h` - holds the current, limited to one controller driver
per board, devicetree independent I2C interface
* `i2c_bus.h` - will become the devicetree compatible interface for
native I2C (e.g. non-SMBus) controllers

This patch adds the necessary changes to support Scarlet revision 1.
Since the differences to revision 0 are so deep, we have decided not to
continue support for it in the same image. Therefore, this patch will
break Scarlet rev0.
All the deviations from other Gru boards are currently guarded by
CONFIG_BOARD_GOOGLE_SCARLET. This should be changed later if we
introduce more variants based on the newer Scarlet board design.

As the hardware designed on gru, the AP_I2C_TP_PU_EN (gpio3_b4) controlled
the SCL/SDA status to avoid leakage. And the gpio3_b4 of rk3399 pull
resistor is 26k~71k and 3.3v for supply power, and gpio3_b4 pin connected
2.2k resistor to i2c of TP device.
The default of this gpio status is pulled up during the start to bootup,
it's very weak drive for the TP device that maybe cause to trigger the
recovery process of elan's firmware.
Also, the Elan updated its firmware(102.0.5.0) to delay checking the
i2c of touchpad is greater than 1 second.
So we have to drive the stronger pull-up within 1 second of powering up
the touchpad to prevent its firmware from falling into recovery.

There are many good reasons why we may want to run some sort of generic
callback before we're executing a reset. Unfortunateley, that is really
hard right now: code that wants to reset simply calls the hard_reset()
function (or one of its ill-differentiated cousins) which is directly
implemented by a myriad of different mainboards, northbridges, SoCs,
etc. More recent x86 SoCs have tried to solve the problem in their own
little corner of soc/intel/common, but it's really something that would
benefit all of coreboot.
This patch expands the concept onto all boards: hard_reset() and friends
get implemented in a generic location where they can run hooks before
calling the platform-specific implementation that is now called
do_hard_reset(). The existing Intel reset_prepare() gets generalized as
soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now
easily be added later if necessary). We will also use this central point
to ensure all platforms flush their cache before reset, which is
generally useful for all cases where we're trying to persist information
in RAM across reboots (like the new persistent CBMEM console does).
Also remove cpu_reset() completely since it's not used anywhere and
doesn't seem very useful compared to the others.

intrinsic to vboot itself) from src/vendorcode/google/chromeos to
src/vboot. Also taking this opportunity to namespace all VBOOT Kconfig
options, and clean up menuconfig visibility for them (i.e. some options
were visible even though they were tied to the hardware while others
were invisible even though it might make sense to change them).

The virtualized developer switch was invented five years ago and has
been used on every vboot system ever since. We shouldn't need to specify
it again and again for every new board. This patch flips the Kconfig
logic around and replaces CONFIG_VIRTUAL_DEV_SWITCH with
CONFIG_PHYSICAL_DEV_SWITCH, so that only a few ancient boards need to
set it and it fits better with CONFIG_PHYSICAL_REC_SWITCH. (Also set the
latter for Lumpy which seems to have been omitted incorrectly, and hide
it from menuconfig since it's a hardware parameter that shouldn't be
configurable.)
Since almost all our developer switches are virtual, it doesn't make
sense for every board to pass a non-existent or non-functional developer
mode switch in the coreboot tables, so let's get rid of that. It's also
dangerously confusing for many boards to define a get_developer_mode()
function that reads an actual pin (often from a debug header) which will
not be honored by coreboot because CONFIG_PHYSICAL_DEV_SWITCH isn't set.
Therefore, this patch removes all those non-functional instances of that
function. In the future, either the board has a physical dev switch and
must define it, or it doesn't and must not.
In a similar sense (and since I'm touching so many board configs
anyway), it's annoying that we have to keep selecting EC_SOFTWARE_SYNC.
Instead, it should just be assumed by default whenever a Chrome EC is
present in the system. This way, it can also still be overridden by
menuconfig.

According to USB 2.0 Spec Table 7-7, the High-speed squelch
detection threshold Min 100mV and Max 150mV, and we set USB
2.0 PHY0 and PHY1 squelch detection threshold to 150mV by
default, so if the amplitude of differential voltage envelope
is < 150 mV, the USB 2.0 PHYs envelope detector will indicate
it as squelch.
On Kevin board, if we connect usb device with Samsung U2 cable,
we can see that the impedance of U2 cable is too big according
to the eye-diagram test report, and this cause serious signal
attenuation at the end of receiver, the amplitude of differential
voltage falls below 150mV.
This patch aims to reduce the PHY0 and PHY1 otg-ports squelch
detection threshold to 125mV (host-ports still use 150mV by
default), this is helpful to increase USB 2.0 PHY compatibility.

The commit 0ba3b2593b0c ("gru: Tuning USB 2.0 PHY to increase
compatibility") bypass ODT to set the max driver strength for
the Type-C otg-port, it works well on otg-port when connected
with USB2.0 devices.
Unfortunately, because the Type-C otg-port and host-port are
consisted in one USB2 PHY, so bypass ODT will have an effect
on both host-port and otg-port. I have tested the host-port
eye-diagram, the result shows that if we bypass ODT, the host-
port eye-diagram height will become to high, more than 500mv,
this may cause USB 2.0 high-speed enumeration failure.
This patch bypass ODT for host-port separately, and then we
can reduce the host-port driver strength without affecting
the otg-port driver strength.

Gru only uses USB 2.0 in firmware to avoid all the madness associated
with Type-C port orientation and USB 3.0 tuning. We do this by isolating
the SuperSpeed lines in the Type-C PHY so it looks like they aren't
connected to the device.
Unfortunately, some devices seem to already get "locked" into SuperSpeed
mode as soon as they detect Rx terminations once, and can never snap out
again on their own. Since the terminations are already connected during
power-on reset we cannot disable them fast enough to prevent this, and
the only solution we found to date is to power-cycle the whole USB port.
Now, Gru's USB port power is controlled by the EC, and unfortunately we
have no direct host command to control it. We do however have a command
to force a certain USB PD "role", and forcing our host into "sink" mode
makes it stop sourcing power to the port. So for lack of a saner
solution we'll use this to work around our problem.

When testing USB 2.0 compatibility with different kinds
of USB 2.0 devices on Kevin board, we find that some
USB HDDs (e.g. seagate SRD00F1 1TB HDD) and some smart
phones (e.g. galaxy A5 smart phone) can't be detected.
And according to the error log, this issue is related
to USB 2.0 PHY signal problem.
For the USB HDD, error log is:
[ 592.557724] usb 5-1: new high-speed USB device number 2 using xhci-hcd
[ 592.847735] usb 5-1: new high-speed USB device number 3 using xhci-hcd

The log shows that HDD failed to high-speed handshake.
For the smart phone, error log is:

[ 1147.671789] usb usb5-port1: unable to enumerate USB device
The log shows that smart phone failed to read device
descriptor, error -71 may be caused by PHY signal problem.
This patch aims to tune USB 2.0 PHY with the following
parameters to support USB HDD, smart phone and some other
potential USB 2.0 devices.
1. Disable the pre-emphasize in chirp state to avoid
high-speed handshake failure.
2. Bypass ODT auto compensation to enable set max driver
strength manually. (Bit[42] of usbphy_ctrl register is
1'b1 for bypass, and Bit[41:37] of usbphy_ctrl register
is 5'b10000 for max driver strength).
3. Bypass ODT auto refresh, and set the max bias current
tuning reference. (Bit[57] of usbphy_ctrl register is
1'b1 for bypass, and Bit[52:50] of usbphy_ctrl register
is 3b'100 for max bias current tuning reference).
We have done the USB 2.0 compliance test and compatibility test
with this patch, it works well.

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.

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.

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

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).

This patch adds support to reboot the whole board after a hardware

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).

This patch sets some magic number in magic undocumented registers that

see any difference (unfortunately it doesn't solve the problems with
long cables on my board), but I guess it doesn't hurt either way.

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.

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.

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).

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.

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.

Add this function and make it return 0, as there is no physical dev switch
(at least I think this is what we are supposed to do).
