Do not use the global platform_i2c_transfer() function that can only be
implemented by a single driver. Instead, make a `struct device` aware
transfer() function the only interface function for I2C controller dri-
vers to implement.
To not force the slave device drivers to be implemented either above
generic I2C or specialized SMBus operations, we support SMBus control-
lers in the slave device interface too.
We start with four simple slave functions: i2c_readb(), i2c_writeb(),
i2c_readb_at() and i2c_writeb_at(). They are all compatible to respec-
tive SMBus functions. But we keep aliases because it would be weird to
force e.g. an I2C EEPROM driver to call smbus_read_byte().

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

Chrome OS systems rely on the write status register to enable/disable
flash write protection and disabling this opcode breaks the ability
to enable or disable write protection with flashrom.
Add a configure option for this feature that will disable the opcode
for Write Status commands unless CONFIG_CHROMEOS is enabled.
Tested to ensure that a default build without CONFIG_CHROMEOS has this
option enabled while a build with CONFIG_CHROMEOS does not. Also
ensured that when this option is disabled (for Chrome OS) then flashrom
can be used with the --wp-enable and --wp-disable commands, depending
on the state of the external write protect pin.

A decision has been made that boards with LATE_CBMEM_INIT
will be dropped from coreboot master starting with next
release scheduled for October 2017.
As existing implementation of CAR teardown in AGESA can only
do either EARLY_CBMEM_INIT or ACPI S3 support, choose the former.
ACPI S3 support may be brought back at a later date for
these platforms but that requires fair amount of work fixing
the MTRR issues causing low-memory corruptions.

We were explicitly passing CC and TARGET_CC to configure but overwrote
that decision later by passing CC (with the value of TARGET_CC) directly
to a recursive make call. The latter overwrite was introduced because
`unexport` alone doesn't work on variables that were specified on a make
command line (they are added to MAKEOVERRIDES and passed to further re-
cursive make calls).
Instead of unexporting random variables, unexport those that were actu-
ally passed from payloads/external/Makefile.inc and clear MAKEOVERRIDES.
Do not pass OBJDUMP as that is nowhere to be found in the GRUB sources.
And, last but not least, add --disable-werror because building GRUB is
very susceptible to changes in the flex version.

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`.

It has been observed on a number of platforms (baytrail, kaby lake)
that if serial console is not enabled in coreboot, but is enabled in
kernel (v4.4), then on resume kernel hangs. In order to fix this, add
support for enabling UART debug port controller on resume.
In order to decide whether UART debug port controller should be
enabled in ramstage, following things are checked in given order:
1. If coreboot has serial console enabled, there is no need to
re-initialize the controller.
2. This special action is taken only for UART debug port controller.
3. If boot is not S3 resume, then initialization is skipped.
4. Callback into SoC to check if it wants to initialize the
controller.
If all the above conditions are met, then UART debug port controller
is initialized and taken out of reset.
BUG=b:64030366
TEST=Verified with the entire patchset series that:
1. If coreboot does not have serial console enabled, but Linux kernel
has console enabled, then on resume, coreboot initializes UART debug
port controller.
2. If coreboot and Linux do not have serial console enabled, then
coreboot does not initialize UART debug port controller.
3. If coreboot has serial console enabled, there is no change in
behavior.

2. Instead of passing in m/n clock divider values as parameters to

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 mainboard features is an G43 northbridge, ICH10 southbridge and
Winbond W83627dhg SuperI/O. This board is impossible to flash
internally with vendor bios (BIOS region is WP and other regions like
IFD and ME are read only and inaccessible respectively). Due to either
ICH10 or board layout it is also impossible to do ISP, which requires
desoldering flash chip. To make hacking more easy there is an empty
SPI header next to spi flash pads which can be hooked up to a SPI
flash.
What works:
* 2 DDR2 dimms per channel (tested with 1+2G in CH0 and 2+2G in CH1);
* SATA with AHCI
* Integrated GPU with option rom (extracted from a Gigabyte vendor
bios)
* VGA (on DVI) with NGI if patched to use DVI gmbus port for output
* PCI
* Reboot and S3 resume
* Descriptor mode with ME disable straps and ME region absent (no
working gbe in this configuration though)
* USB.
What does not work:
* GBE (probably requires working ME);
* Analog on DVI port out is shaking, which is not the case with vendor
BIOS (setting clockgen on smbus 0x69 like vendor fixes it).
* Booting with ME enabled (needs raminit patches for that)
Not tested:
* Sound;
* All the rest.
Not coreboot related problems:
* Flashing this board with vendor bios is a PITA and requires
desoldering flash chip;
* In situ programming is not possible.
TESTED with SeaBIOS and Linux 4.10.8

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