There is at least one I2C device (being used by Soraka) that has 3
controls -- enable, reset and stop. If the stop gpio is not put into
the right state when turning off the device in suspend mode, then it
causes leakage. Thus, we need control in power resource to be able to
stop the device when entering suspend state.
BUG=b:64987428
TEST=Verified on soraka that touchscreen stop is correctly configured
on suspend.

Replaces the ics/954309 driver with a more generic version to
accommodate clockgens with a different amount of registers.
It also features a mask to only touch certain bits of the clockgen.
TODO: set appropriate mask for X60/T60 since the datasheets for their
clockgens can be found.

This patch to ensure that coreboot is able to store memory
training data into SPI and perform platform lockdown after
PCI enumeration is done before handing over control to
NotifyPhase() - Post PCI enumeration.
Modified coreboot bootstate execution order below:
BS_DEV_ENUMERATE - BS_ON_EXIT - Store Memory training data into SPI
BS_DEV_RESOURCES - BS_ON_EXIT - Platform Lock Down after PCI enumeration
BS_DEV_ENABLE - BS_ON_ENTRY - NotifyPhase() post PCI enumeration
TEST=Please find test case and results for Chrome Devices as Apollolake- Reef,
Kabylake-Eve and Poppy and Non Chrome Devices with Yocto OS.

Split `i2c.h` into three pieces to ease reuse of the generic defi-
nitions. No code is changed.
* `i2c.h` - keeps the generic definitions
* `i2c_simple.h` - holds the current, limited to one controller driver
per board, devicetree independent I2C interface
* `i2c_bus.h` - will become the devicetree compatible interface for
native I2C (e.g. non-SMBus) controllers

postcar.c and replace it with an empty weak function.
This patch omits checking if (IS_ENABLED(CONFIG_FSP_CAR)). The
temp_ram_exit.c file with the real fsp_temp_ram_exit() is only built
when CONFIG_FSP_CAR is true.

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`.

Get rid of old hybrid graphics driver and use the new one.
1. Disable IGD and PEG in early romstage.
The PEG port will get disabled on devices that do not have a
discrete GPU. The power savings are around ~1Watt.
The disabled IGD does no longer waste GFX stolen memory.
2. Get rid of PCI driver
The Nvidia GPU can be handled by the generic PCI driver and allows
to use the ACPI _ROM generator for Switchable graphics.
3. Settings are stored in devicetree.
One driver for all Lenovo hybrid graphics capable devices.
4. Add support for Thinker1 GPU power handling.
Only boards that do use reference design 2012 are known to be
supported. Needs test on boards that do you use reference design 2013.
Should reduce idle power consumption when using IGD by ~5Watt.
Tested on Lenovo T430 without DGPU. PEG port is disabled.
Needs test on all devices.

Introduce a chip_driver that uses devicetree instead of Kconfig.
The new driver has the following advantages:
* No more wasted IGD GFX stolen memory
* Can be used by T500 series
* Is even run on devices that do not have a dGPU installed
* Can disable unused PEG port on devices without dGPU (and save power)
* Use devicetree instead of Kconfig options
* Support for multiple hybrid GPIO active levels
* Support for backlight control GPIO
* Support for _ROM on Optimus capable devices
The driver is split into romstage part and ramstage part.
Every mainboard has to call the driver in romstage to get the requested
GPU state. The mainboard code then has to toggle GPU power or disable
the IGD or PEG port.
The ramstage part does handle the hygrid graphics GPIO, including
optional backlight mux GPIO. Every GPIO can have it's own active level,
as defined in devicetree. Devices are no longer disabled in ramstage.
The existing hybrid graphics driver does the same configuration and
should not interfere with this commit until it has been removed.

This commit adds a new driver for the RT5663 codec to use instead

driver-specific device properties we need a BIOS driver that can
provide those properties.
The kernel driver devicetree properties for this codec are at:

The function find_fsp() parses the FSP header and returns either a valid
pointer to the FSP_INFO_HEADER or an error code. The caller of
find_fsp() only takes care about a NULL-pointer but not about a possible
error code. This leads to memory access violations in case of error when
FspTempRamInit is called.
To avoid this and to let the user know that there was an error while
parsing the FSP header show an error message and the error code.

The macro FPGA_SET_PARAM was introduced to make the setting of different
FPGA registers with the appropriate values from hwinfo more
transparent. The hwilib takes care about the size of the provided buffer
where the requested value should be stored in. The fields in hwinfo have
not always the same size as the matching registers in the FPGA. So to
avoid errors resulting in a too small buffer when calling hwilib_get_field()
the buffer is now fixed to 32 bit and will be casted to the destination
type when the value is written into the FPGA register.
Changing the field size in hwilib would be the wrong way as the defined
lengths are specified this way to be expandable in the future.
In addition the number of maximum supported temperature sensors is
increased to 8 as the FPGA now supports more.

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.

Commit 2e7f6cc introduced the 'no graphics init' option for
FSP 1.1 SoCs using a GOP driver to init the display, but selecting
that option while including a VBT breaks compilation for Braswell

This patch decouples the VBT from the GOP driver execution,
allowing the 'no graphics init' option to compile (and work)
properly when CONFIG_ADD_VBT_DATA_FILE=y.

If CONSOLE_SPI_FLASH config is enabled, we write the cbmem
messages to the 'CONSOLE' area in FMAP which allows us to grab the
log when we read the flash.
This is useful when you don't have usb debugging, and
UART lines are hard to find. Since a failure to boot would
require a hardware flasher anyways, we can get the log
at the same time.
This feature should only be used when no alternative is
found and only when we can't boot the system, because
excessive writes to the flash is not recommended.
This has been tested on purism/librem13 v2 and librem 15 v3 which
run Intel Skylake hardware. It has not been tested on other archs
or with a driver other than the fast_spi.

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.

We have several different UART implementations of which three support a
timeout when receiving characters. In all of these three implementations
there is a bug where when the timeout is hit the last received character
will be returned instead of the needed 0.
The problem is that the timeout variable i is decremented after it has
been checked in the while-loop. That leads to the fact that when the
while-loop is aborted due to a timeout i will contain 0xffffffff and not
0. Thus in turn will fool the following if-statement leading to wrong
return value to the caller in this case. Therefore the caller will see a
received character event if there is none.

spi_crop_chunk is a property of the SPI controller since it depends
upon the maximum transfer size that is supported by the
controller. Also, it is possible to implement this within spi-generic
layer by obtaining following parameters from the controller:
1. max_xfer_size: Maximum transfer size supported by the controller
(Size of 0 indicates invalid size, and unlimited transfer size is
indicated by UINT32_MAX.)
2. deduct_cmd_len: Whether cmd_len needs to be deducted from the
max_xfer_size to determine max data size that can be
transferred. (This is used by the amd boards.)

FSP_PLATFORM_MEMORY_SETTINGS_VERSIONS, which incorproates the SoC

passed to the platform. The lower 8 bits of the FSP version are the
build number which in practice is normally 0. Use those 8 bits to
include the SoC and mainboard memory settings version. When FSP,

ramstage and romstage. In order to provide clearer and consistent
semantics two new macros are provided:
1. DEVTREE_EARLY which is true when !ENV_RAMSTAGE
2. DEVTREE_CONST as a replacment for ROMSTAGE_CONST
The ROMSTAGE_CONST attribute is used in the source code to mark
the devicetree data structures as const in early stages even though
it's not just romstage. Therefore, rename the attribute to
DEVTREE_CONST as that's the actual usage. The only place where the
usage was not devicetree related is console_loglevel, but the same
name was used for consistency. Any stage that is not ramstage has
the const C attribute applied when DEVTREE_CONST is used.

The SD/MMC support is broken into several pieces. There are three main
data structures:
* sdhci_ctrlr - This is SDHCI controller specific and defined in
include/device/sdhci.h
* sd_mmc_ctrlr - This contains generic controller management data and
defined in include/device/sd_mmc_ctrlr.h
* storage_media - This contains the flash storage device management data
and is defined in include/device/storage.h
The SD/MMC driver consists of several components:
* SDHCI controller code
* bouncebuf.c
* bouncebuf.h
* pci_sdhci.c
* sdhci.c
* sdhci.h
* sdhci_adma.c
* sdhci_display.c
* Flash storage device support
* mmc.c
* mmc.h
* sd.c
* sd_mmc.c
* sd_mmc.h
* storage.c
* storage.h
* storage_erase.c
* storage_write.c
Kconfig values enable various portions of the controller and storage
drivers to be built to reduce the overall size of what is included in
the final image.
Full read/write/erase operations are provided for those platforms which
want to take advantage. It is also possible to build the driver to
perform initialization only. By default, this driver is not included in
any platform, platforms must specifically select DRIVERS_STORAGE to add
the SD/MMC support.
After this patch is reviewed and merged, there are some additional
patches:
* Common CAR storage area - Use a predefined region of CAR to pass data
structures between bootblock through to romstage. This allows early
stages to preform the SD/MMC device initialization and later stages
to use the SD/MMC device without further initialization. The example
code initializes the SD/MMC device in bootblock and uses the SD/MMC
device in romstage without further initialization.
* CBMEM ID - Add a CBMEM ID value for the data structures so that they
may be passed from romstage to ramstage and eventually the payload.
The example uses the SD/MMC device in ramstage without further
initialization.
* Move the SD/MMC driver into commonlib
* Have libpayload build the SD/MMC driver from commonlib. The intent
is to pass the controller state to libpayload so that the SD/MMC
device can be used without further initialization.
* On some platforms, have depthcharge use the commonlib SD/MMC driver
History:
Copy the SD/MMC driver from depthcharge revision eb583fa8 into coreboot
and make the following changes:
* Removed #include "config.h" from mmc.c, allow the lint tests to pass.
* Move include files from drivers/storage into include/device.
* Rename mmc.h to storage.h.
* Add the Kconfig and Makefile and make edits to get the code to build.
* Add support to initialize a PCI controller.

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.
