To help identify the licenses of the various files contained in the

Any file in the coreboot project without a specific license is bound

This patch adds the GPL V2 license identifier to the top of all

When PTN3460_EARLY_INIT is selected, the PTN3460 (DP-2-LVDS-bridge) will
be initialized before all devices are initialized. This is necessary to
get a valid EDID data set into the PTN3460 before the graphic controller
is initialized in order to be able to show a splash screen.
For ptn3460_init() to work properly the I2C bus this bridge is connected
to needs to be initialized. As this I2C bus initialization would be done
too late in the normal flow, it needs to be called here explicitly
before ptn3460_init() to initialize the I2C bus with the needed
conditions. Otherwise the default I2C settings of the controller will be
used which results in a clock rate too high for this mainboard.
Test=Measure I2C bus signals and make sure that the clock is <= 400 kHz.

available in ChromeOS kernel fork of 4.4 and 5.4. Linux later accepted
a different implementation named SX9324 and has been available since
5.4. Ideally all variants should adopt the new driver; however, during
the transition phase, coreboot must support both drivers. It is better
to have a single firmware build that can work with both Linux kernel
drivers by specifying both sets of properties. Legacy driver support

The check was recently removed to allow callers to pass `count == 0`.
Dereferencing the `msg` array is invalid in that case, though. Linux,
where we borrowed the i2c interface from, also treats this with -EINVAL.

The current 10ms timeout for SPI TPM IRQ is not enough for platforms
using ti50 (such as corsola). Therefore, introduce a new Kconfig option
'GOOGLE_TPM_IRQ_TIMEOUT_MS'.
For platforms using cr50, we need to support legacy pre-ready-IRQ cr50
factory images during the initial boot, so the timeout remains 100ms for
I2C TPM and 10ms for SPI TPM. For all the other platforms using ti50,
the default timeout is increased to 750ms, as suggested by the ti50 team
(apronin@google.com).

Add 'detect' flag which can be attached to devices which may or may not
be present at runtime, and for which coreboot should probe the i2c bus
to confirm device presence prior to adding an entry for it in the SSDT.
This is useful for boards which may utilize touchpads/touchscreens from
multiple vendors, so that only the device(s) present are added to the
SSDT. This relieves the burden from the OS to detect/probe if a device
is actually present and allows the OS to trust the ACPI _STA value.

0-byte writes can be used as a way to probe/check presence of an i2c
device, so adjust _dw_i2c_transfer() to immediately set the STOP bit
and raise logger level for TX abort messages when the segment length
is zero. Adjust dw_i2c_transfer() to allow zero-segment-length
messages to be passed thru to _dw_i2c_transfer().
Tested as part of entire i2c-detect patch train.

A new iteration of Google's TPM implementation will advertize a new
DID:VID, but otherwise follow the same protocol as the earlier design.
This change makes use of Kconfigs TPM_GOOGLE_CR50 and TPM_GOOGLE_TI50
to be able to take slightly different code paths, when e.g. evaluating
whether TPM firmware is new enough to support certain features.

Break TPM related Kconfig into the following dimensions:
TPM transport support:
config CRB_TPM
config I2C_TPM
config SPI_TPM
config MEMORY_MAPPED_TPM (new)
TPM brand, not defining any of these is valid, and result in "generic" support:
config TPM_ATMEL (new)
config TPM_GOOGLE (new)
config TPM_GOOGLE_CR50 (new, implies TPM_GOOGLE)
config TPM_GOOGLE_TI50 (new to be used later, implies TPM_GOOGLE)
What protocol the TPM chip supports:
config MAINBOARD_HAS_TPM1
config MAINBOARD_HAS_TPM2
What the user chooses to compile (restricted by the above):
config NO_TPM
config TPM1
config TPM2
The following Kconfigs will be replaced as indicated:
config TPM_CR50 -> TPM_GOOGLE

This driver uses the ACPI Device Property interface to generate
