Many ChromeOS devices use a GPIO to reset the system, in order to
guarantee that the TPM cannot be reset without also resetting the CPU.
Often chipset/SoC hardware watchdogs trigger some kind of built-in
CPU reset, bypassing this GPIO and thus leaving the TPM locked. These
ChromeOS devices need to detect that condition in their bootblock and
trigger a second (proper) reboot.
This patch adds some code to generalize this previously
mainboard-specific functionality and uses it on Veyron boards. It also
provides some code to add the proper eventlog entry for a watchdog
reset. Since the second reboot has to happen before firmware
verification and the eventlog is usually only initialized afterwards, we
provide the functionality to place a tombstone in a memlayout-defined
location (which could be SRAM or some MMIO register that is preserved
across reboots).

we use the delay 200ms to meet the edp power timing request before,
it waste time, so we use the HPD function to detect the edp panel now.
In previous version, the hardware may not support the edp HPD function,
so in the code it will spend 200ms to detect hpd single, if it don't get
the hpd single, it will contiue the edp initialization process, to compatible
all of the hardware version.

This moves PMIC_BUS from each mainboard's board.h file to a per-
mainboard Kconfig variable. To prevent humans from forgetting to
set a valid value, an invalid default is set in the rk3288 Kconfig
and checked in rk808.c so that compilation will fail if the mainboard
Kconfig does not override it.
Originally, PMIC_BUS was only used by mainboard code as an argument
to RK808 PMIC functions. To conform to the generic RTC API, however,
the RK808 code needs to have the bus number globally defined somewhere
since the rtc_get() and rtc_set() functions don't take any args.
Since CONFIG_PMIC_BUS is globally visible, we no longer need to pass
bus number to the PMIC functions.

Due to a missing i2c_init(), we were actually running our TPM with
default divisors at 660KHz. Oops.
While it's commendable that both the TPM and our controller seem to have
been running fine all this time at more than 1.5 times the maximum
frequency they support, we should probably still get that fixed.
Also sync Speedy back up to the other Veyron boards since it seems to
have missed a recent SDMMC patch.

The only way to reliably reset an SD card in an unknown state is by
power-cycling. Since a kernel may crash and reboot at any point, SD
cards may be left in one of them fancy high-throughput modes that
depthcharge (or, in fact, a newly booting kernel without prior
knowledge) doesn't support, so we need to reset the card on every boot.
This patch adds support to turn off an RK808 regulator completely and
uses that to turn off SD card power rails in early romstage. The time
until configure_sdmmc() in ramstage turns them back on should be more
than enough to drain the power rail for an effective power-cycle.

This patch adds support for Pinky rev3 (board ID 2) and Jerry rev2: the
power button GPIO changed polarity to low, the 5V_DRV pin for USB power
was moved to the AP again (welcome back!), and the EMMC_RST_L is now
finally on a port with the right IO voltage so we don't need any weird
pull-up tricks anymore. Since there are very few Jerry rev1s around,
we'll just move it over to the new code directly without introducing
board ID differences (also, because I have no idea how they stuffed it
this time... is this one actually called rev2?).

LDO7 (VCC10_LCD_PWREN_H) is essentially just a glorified GPIO that turns
the real VCC10 regulator on or off. We tried setting it to 3.3V since it
matches the VCC33_SYS voltage on the input of that regulator. However,
we didn't notice that the LDO only supports going up to 2.5V.
This patch changes the voltage to the allowed maximum, which should
still work fine as an enable line (and is the same value used by the
kernel). This removes an assertion error in the ramstage.
Also change the PMIC driver to assert maximum VSEL values based on the
LDO, because the lower-voltage ones support one more setting. (LDO3 is
actually listed to only go up to 0b1111 in the manual, and has a weird
jump from 0b1101 -> 2.2V (skipping over 0b1110) to 0b1111 -> 2.5V. I
don't know if that's a documentation error or what they were smoking
when they designed that, but we don't need to care for now.)

The eMMC enable pin is in a 3.3V IO domain. Unfortunately the eMMC
expects this pin to be 1.8V. The way we were driving this pin would
cause the eMMC to pull power through this pin and that was causing
current leaks.
In future revisions of hardware we should move this pin somewhere more
legit. However, in the current hardware we can get things working
pretty well by using a pullup to "drive" this pin. This will work in
conjunction with the external 100K pullup to give a somewhat
reasonable voltage. The eMMC will also not be able to pull much
current through this pin, so it can't leak too badly.
