This change sets default bus speed as I2C_SPEED_FAST instead of
I2C_SPEED_STANDARD when board does not provide any speed. This makes
it similar to all other i2c drivers in coreboot.

Added new routine cr50_i2c_probe() which ensures that communication
with the Cr50 over I2C is good prior to attempting other initialization
of the Cr50 and TPM state. This avoids a race condition when the Cr50
is first booting that it may reset it's I2C slave interface during the
first few I2C transactions initiated from coreboot.
BUG=b:120009037
BRANCH=none
TEST=Run the Cr50 factory update against Careena board. Confirm that
I2C reads are retried until the DID VID is valid. Tested against debug
Cr50 firmware that forced failure of cr50_i2c_probe() and verfied that
coreboot shows recovery screen.

Add an entry to the soc_clock table for a 216MHz clock so that
the I2C controller clock is calculated correctly when the I2C
bus is used in coreboot.
This was tested by measuring the I2C clock speed on H1 I2C bus
on a sarien board in coreboot and ensuring it is ~400KHz.

Its spreading copies got out of sync. And as it is not a standard header
but used in commonlib code, it belongs into commonlib. While we are at
it, always include it via GCC's `-include` switch.
Some Windows and BSD quirk handling went into the util copies. We always
guard from redefinitions now to prevent further issues.

Under some conditions, cr50_i2c_read() can return without actually reading
the TPM, which will leave access uninitialized. Set an initial value for

The purpose of this is to enable the device's calibration information
to be stored in firmware, and then transferred over to the kernel
via ACPI.
This device has more than 10 individual configuration parameters,
so they would not fit in the generic driver's properties table.

The chip PCA9538 is a 8 bit I/O expander connected to the systems I2C
bus. Add a chip driver to support this chip.
Beside the pure chip driver two interface functions are provided to read
the state of the pins and write output values to the pins.
As the slave address of this chip is hardware configurable the function
pca9538_get_dev() is used to get the right slave address. This function
needs to be implemented in mainboard code if one needs to use the
interface functions to read and write I/O state.

The designware i2c controller indicates that the slave address
shouldn't be programmed while the controller is enabled. Therefore,
switch the ordering of the slave target address and the enable.
Additionally, ensure the controller is disabled prior to the
start of the slave programming sequence.
Lastly, chunk up the i2c_msg segments at differing slave address
boundaries. That allows for simpler programming for the controller
by only doing one slave address transaction chunk at a time.

Right now dw_i2c_get_soc_cfg() is expecting the SoC to implement
that callback for obtaining the bus config. However, we're currently
forcing another parameter of struct device so one can do the lookup.
This works for Intel-based systems since the struct device was needed
to program the BAR, etc. However, from an API standpoint, it just
complicates matters by needing to obtain the struct device. The SoC
already has knowlege of its own devices so it can get the config
itself by bus number. Therefore, remove that contraint from the API.

If one wants to implement both i2c_bus.h and i2c_simple.h APIs
the compilation unit needs to be guarded or coordinated carefully
with different compilation units. Instead, name the i2c_bus
functions with _dev such that it indicates that they operate on
struct device. One other change to allow i2c_bus.h to be built in
non-ramstage environments is to ensure DEVTREE_CONST is used for
the dev field in struct bus.

The Cr50 i2c driver provides separate entry points for probing and
initialization, but probing function does not really do much.
It also claims and releases locality on every coreboot stage, but
there is no need for this - locality should be definitely claimed
after reset and then it could be retained through the boot process.
On top of that the driver does not properly account for long time it
could take the Cr50 chip to come around to reset processing if TPM
reset request was posted during a lengthy TPM operation.
This patch addresses the issues as follows:
- tpm_vendor_probe() and tpm_vendor_cleanup() become noops, kept
around to conform to the expected driver API.
- tpm_vendor_init() invokes a function to process TPM reset only in
the first stage using TPM (typically verstage), the function
checks if locality is claimed and if so - waits for it to be
released, which indicates that TPM reset processing is over.
- before claiming locality check if it is already taken, and if so -
just proceed.

Our current struct for I2C segments `i2c_seg` was close to being compa-
tible to the Linux version `i2c_msg`, close to being compatible to SMBus
and close to being readable (e.g. what was `chip` supposed to mean?) but
turned out to be hard to fix.
Instead of extending it in a backwards compatible way (and not touching
current controller drivers), replace it with a Linux source compatible
`struct i2c_msg` and patch all the drivers and users with Coccinelle.
The new `struct i2c_msg` should ease porting drivers from Linux and help
to write SMBus compatible controller drivers.
Beside integer type changes, the field `read` is replaced with a generic
field `flags` and `chip` is renamed to `slave`.
Patched with Coccinelle using the clumsy spatch below and some manual
changes:
* Nested struct initializers and one field access skipped by Coccinelle.
* Removed assumption in the code that I2C_M_RD is 1.
* In `i2c.h`, changed all occurences of `chip` to `slave`.

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 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

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.

Linux kernel expects that power management with ACPI should always be
handled using PowerResource. However, some kernel drivers (e.g. ELAN
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
PowerResource to control power to the device.
Update mainboards to export reset GPIO as well as PowerResource for
ELAN touchscreen device.

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 initialized after the battery is
completely drained the bits for power_mode and cof_selection are set up
with wrongly applied masks.
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
cof_selection are not shifted to the right position.
Both errors lead to a wrong initialization of the RTC and in turn to a
way larger current consumption (instead of 120 nA the RTC current rises
to over 2 µA).
This patch fixes both errors and the current consumption is in the right
range again.
