According to the datasheet the RTC needs a power rising slope of no more
than 100µs/V to ensure a correct power-on reset. If the mainboard that
hosts the RTC cannot guarantee this, a software reset sequence is needed
in the case where the battery was drained completely.
As the rising slope of the power supply depends on so many parameters
and is highly mainboard specific, refactor the initialization code to
perform a software reset every time a power loss event is recognized by
the RTC.

The RTC RX6110SA has several configuration options which might be
interesting to set. To make this setup independent of the driver itself
but let it still be configurable on mainboard level, add more
configuration options to the chip driver.

The driver for the RTC RX6110SA is designed to be used with I2C bus.
This patch adds the possibility to use SMBus operations to access the
RTC. For this purpose the Kconfig switch RX6110SA_USE_SMBUS is added. It
is not enabled per default so that I2C will be used. One can set this
switch on board level to use SMBus instead.

This driver enables the usage of the external RTC chip RX6110 SA
(http://www5.epsondevice.com/en/products/i2c/rx6110sab.html) which is
connected to the I2C bus. The I2C address of this device is fixed. One
can change parameters in the device tree so that the used setup can be
adapted to match the configuration of the device on the mainboard.

The vendor.irq field was originally intended for use as the TPM 1.2
"command complete" interrupt. However, all actual coreboot tpm drivers
and hardware use the vendor.status method of checking command completion
instead, and this irq field is not used.
Let's just remove this unused functionality to simplify the code.

The Cr50 TPM uses an IRQ to provide a "status" signal used for hand-shaking
the reception of commands. Real IRQs are not supported in firmware,
however firmware can still poll interrupt status registers for the same
effect.
Commit 94cc485338a3 ("drivers/i2c/tpm/cr50: Support interrupts for status")
added support for the Cr50 driver on X86 platforms to use a KConfig file
to supply an IRQ which it would poll using acpi_get_gpe. If the IRQ is
not supplied, the Cr50 driver inserts a 20 ms wait.
Unfortunately this doesn't work so well when using the i2c connected Cr50
on ARM platforms. Luckily, a more generic implementation to allow a
mainboard to supply a Cr50 IRQ status polling function was solved for SPI
connected Cr50s by commit 19e3d335bddb ("drivers/spi/tpm: using tpm irq to
sync tpm transaction").
Let's refactor the i2c c50 driver to use this same approach, and change
eve and reef boards to make use of DRIVER_TPM_TIS_ACPI_INTERRUPT for
specifying the TPM flow control interrupt.
This essentially reverts these two commits:
48f708d199 drivers/i2c/tpm/cr50: Initialize IRQ status handler before probe
94cc485338 drivers/i2c/tpm/cr50: Support interrupts for status
And ports this commit to i2c/tpm/cr50:
19e3d335bd drivers/spi/tpm: using tpm irq to sync tpm transaction
As a side effect the tpm_vendor_specific IRQ field goes back to its
original usage as the "TPM 1.2 command complete" interrupt, instead of
being repurposed to hold the flow control IRQ.

In builds without CONFIG_VBOOT_SEPARATE_VERSTAGE, verstage files are
linked directly into the bootblock or the romstage. However, they're
still compiled with a separate "libverstage" source file class, linked
into an intermediate library and then linked into the final destination
stage.
There is no obvious benefit to doing it this way and it's unclear why it
was chosen in the first place... there are, however, obvious
disadvantages: it can result in code that is used by both libverstage
and the host stage to occur twice in the output binary. It also means
that libverstage files have their separate compiler flags that are not
necessarily aligned with the host stage, which can lead to weird effects
like <rules.h> macros not being set the way you would expect. In fact,
VBOOT_STARTS_IN_ROMSTAGE configurations are currently broken on x86
because their libverstage code that gets compiled into the romstage sets
ENV_VERSTAGE, but CAR migration code expects all ENV_VERSTAGE code to
run pre-migration.
This patch resolves these problems by removing the separate library.
There is no more difference between the 'verstage' and 'libverstage'
classes, and the source files added to them are just treated the same
way a bootblock or romstage source files in configurations where the
verstage is linked into either of these respective stages (allowing for
the normal object code deduplication and causing those files to be
compiled with the same flags as the host stage's files).
Tested this whole series by booting a Kevin, an Elm (both with and
without SEPARATE_VERSTAGE) and a Falco in normal and recovery mode.

Add support for using GPIO IRQ instead of PIRQ with an I2C device.
This allows a device to use an edge triggered interrupt that will
trigger on both high and low transitions.
The _DSD method for describing these GPIOs has a field for 'active
low' which is supposed to be 1 if the pin is active low, otherwise
is zero. The value in here doesn't mean too much for GpioInt() as
those will end up using the value from GpioInt() when it actually
requests the interrupt.

touchscreen) check to see if reset gpio is passed in by the BIOS to
decide whether the device loses power in suspend. Thus, until the kernel
has a better way for drivers to query if device lost power in suspend,
we need to allow passing in of GPIOs via _CRS as well as exporting

We've found that the SLB9645 TPM sometimes seems to randomly start
returning 0xFF bytes for all requests. The exact cause is yet unknown,
but we should try to write our TIS code such that it avoids bad
interactions with this kind of response (e.g. any wait_for_status()
immediately succeeds because all "status bits" are set in the response).
At least for status and burstCount readings we can say for sure that the
value is nonsensical and we're already reading those in a loop until we
get valid results anyway, so let's add code to explicitly discount 0xFF
bytes.

In the case where the RTC is re-initialized again with no power-loss
after the last initialization the bits for cap_sel, power_mode and

Both errors lead to a wrong initialization of the RTC and in turn to a

UX Doc = go/gale-hw-ui
This color wasn't changed earlier as the change wasn't done in
the OS also. However, since we cannot change this later in FW
(but OS can change anytime), I am making this change after discussing
with the UX team.
BUG=b:31501528, b:31633562
TEST=Change the device state to 'recovery mode' to observe the new
color.

Remove the support for the second controller and also the
corresponding microcode. The color values used are the same
as onHub (Arkham to be specific).

Kconfig hex values don't need to be in quotes, and should start with
'0x'. If the default value isn't set this way, Kconfig will add the
0x to the start, and the entry can be added unnecessarily to the
defconfig since it's "different" than what was set by the default.
A check for this has been added to the Kconfig lint tool.

Add a config option to the generic I2C device driver to indicate to
the OS that this device should be probed before being added.
This can be used to provide ACPI device instantiations to devices that
may not actually exist on the board. For example, if multiple trackpad
vendors are supported on the same board they can both be described in
ACPI and the OS will probe the address and load the driver only if the
device responds to the probe at that address.

Support reading the ACPI GPE status (on x86) to determine when
the cr50 is ready to return response data or is done processing
written data. If the interrupt is not defined by Kconfig then
it will continue to use the safe delay.
This was tested with reef hardware and a modified cr50 image
that generates interrupts at the intended points.

Originally I thought it would be cleaner to keep this code in one
place, but as things continue to diverge it ends up being easier
to split this into its own driver. This way the different drivers
in coreboot, depthcharge, and the kernel, can all be standalone
and if one is changed it is easier to modify the others.
This change splits out the cr50 driver and brings along the basic
elements from the existing driver with no real change in
functionality. The following commits will modify the code to make
it consistent so it can all be shared with depthcharge and the
linux kernel drivers.
