cab1c01885 mrc: Add support for separate training cache in recovery mode
1. Re-factor MRC cache driver to properly select RW_MRC_CACHE or
RECOVERY_MRC_CACHE based on the boot mode.
 - If normal mode boot, use RW_MRC_CACHE, if available.
 - If recovery mode boot:
    - Retrain memory if RECOVERY_MRC_CACHE not present, or recovery is
    requested explicity with retrain memory request.
    - Use RECOVERY_MRC_CACHE otherwise.
2. Protect RW and RECOVERY mrc caches in recovery and non-recovery boot
modes. Check if both are present under one unified region and protect
that region as a whole. Else try protecting individual regions.
3. Update training data in appropriate cache:
 - Use RW_MRC_CACHE if normal mode.
 - Use RECOVERY_MRC_CACHE if present in recovery mode. Else use
 RW_MRC_CACHE.
4. Add proper debug logs to indicate which training data cache is used
at any point.

1d33488968 drivers/i2c/generic: Re-factor SSDT generation code
1. Export i2c_generic_fill_ssdt to allow other device-specific i2c
drivers to share and re-use the same code for generating AML code for
SSDT. In order to achieve this, following changes are required:
 a. Add macro I2C_GENERIC_CONFIG that defines a structure with all
 generic i2c device-tree properties. This macro should be placed by the
 using driver at the start of its config structure.
 b. Accept a callback function to add any device specific information to
 SSDT. If generic driver is used directly by a device, callback would be
 NULL. Other devices using a separate i2c driver can provide a callback
 to add any properties to SSDT.
2. Allow device to provide _CID.

callbacks for generating AML code for GPIO manipulation.

Device requiring PowerResource needs to define following parameters:
1. Reset GPIO - Optional, GPIO to put device into reset or take it out
of reset.
2. Reset delay - Delay after reset GPIO is de-asserted (default 0).
3. Enable GPIO - Optional, GPIO to enabled device.
4. Enable delay - Delay after enable GPIO is asserted (default 0).

fbf2c79b48 drivers/i2c/generic: Add config for marking device as probed
Add a config option to the generic I2C device driver to indicate to
the OS that this device should be probed before being added.

This can be used to provide ACPI device instantiations to devices that
may not actually exist on the board.  For example, if multiple trackpad
vendors are supported on the same board they can both be described in
ACPI and the OS will probe the address and load the driver only if the
device responds to the probe at that address.

2e77e0aa3f intel/gma/vbt.c: pad the ID string with spaces.
The VBT id string is 20 characters long.
If the string is shorter than 20 it needs spaces at the end.
This change is cosmetic as all strings were padded by hand.

94cc485338 drivers/i2c/tpm/cr50: Support interrupts for status
Support reading the ACPI GPE status (on x86) to determine when
the cr50 is ready to return response data or is done processing
written data.  If the interrupt is not defined by Kconfig then
it will continue to use the safe delay.

This was tested with reef hardware and a modified cr50 image
that generates interrupts at the intended points.

2ea13c8699 drivers/i2c/tpm: Split cr50 driver from main driver
Originally I thought it would be cleaner to keep this code in one
place, but as things continue to diverge it ends up being easier
to split this into its own driver.  This way the different drivers
in coreboot, depthcharge, and the kernel, can all be standalone
and if one is changed it is easier to modify the others.

This change splits out the cr50 driver and brings along the basic
elements from the existing driver with no real change in
functionality.  The following commits will modify the code to make
it consistent so it can all be shared with depthcharge and the
linux kernel drivers.
