Do not use the global platform_i2c_transfer() function that can only be

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().

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.

There are many good reasons why we may want to run some sort of generic
callback before we're executing a reset. Unfortunateley, that is really
hard right now: code that wants to reset simply calls the hard_reset()
function (or one of its ill-differentiated cousins) which is directly
implemented by a myriad of different mainboards, northbridges, SoCs,
etc. More recent x86 SoCs have tried to solve the problem in their own
little corner of soc/intel/common, but it's really something that would
benefit all of coreboot.
This patch expands the concept onto all boards: hard_reset() and friends
get implemented in a generic location where they can run hooks before
calling the platform-specific implementation that is now called
do_hard_reset(). The existing Intel reset_prepare() gets generalized as
soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now
easily be added later if necessary). We will also use this central point
to ensure all platforms flush their cache before reset, which is
generally useful for all cases where we're trying to persist information
in RAM across reboots (like the new persistent CBMEM console does).
Also remove cpu_reset() completely since it's not used anywhere and
doesn't seem very useful compared to the others.
