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

[ 595.574816] usb 5-1: new high-speed USB device number 15 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.

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).

google_chromeec_init() is a weird function that can lead to confusing

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

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).

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)
