2016-09-19drivers/i2c/tpm: Split cr50 driver from main driverDuncan Laurie
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.

Implement postcar stage cbmem console support. The postcar stage is more like ramstage in that RAM is already up. Therefore, in order to make the cbmem console reinit flow work one needs the cbmem init hook infrastructure in place and the cbmem recovery called. This call is added to x86/postcar.c to achieve that. Additionally, one needs to provide postcar stage cbmem init hook callbacks for the cbmem console library to use. A few other places need to become postcar stage aware so that the code paths are taken. Lastly, since postcar is backed by ram indicate that to the cbmem backing store.

The ACPI options for Chrome EC are contained in the variant/ec.h header so the actual code #includes can just reside in dstd.asl. Since most of the mainboard specific peripherals are auto generated by the acpigen from devicetree there's no real separate need for mainboard.asl.
