kbuild: automatically include ECs This change switches all ECs and the generic EC ACPI code to be autoincluded by Makefile.inc, rather than having to be mentioned explicitly in ec/Makefile.inc or in ec/<vendor>/Makefile.inc. This means, vendor and ec directories are now "drop in", e.g. be placed in the coreboot directory hierarchy without having to modify any higher level coreboot files. The long term plan is to enable out of tree components to be built with a given coreboot version (given that the API did not change).

ec/google: Generalize communication protocol support in EC drivers. Since EC protocol v3, the packet format will be the same for all buses (inclding I2C, SPI, and LPC). That will simplify the implementation in each individual bus driver source file. To prepare for that, we will move the protocol part into crosec_proto.c: crosec_command_proto, with bus driver in callback "crosec_io".

ec/google: Support Google's Chrome EC on I2C interface. Google's Chrome EC can be installed on LPC or I2C bus, using different command protocol. This commit adds I2C support for devices like Google/Snow. Note: I2C interface cannot be automatically probed so the bus and chip number must be explicitly set. Verified by booting Google/Snow, with following console output: Google Chrome EC: Hello got back 11223344 status (0) Google Chrome EC: version: ro: snow_v1.3.108-30f8374 rw: snow_v1.3.128-e35f60e running image: 1 Change-Id: I8023eb96cf477755d277fd7991bdb7d9392f10f7 Signed-off-by: Hung-Te Lin <hungte@chromium.org> Reviewed-on: http://review.coreboot.org/3074 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Ronald G.

ec/google: Isolate EC bus protocol implementation. The Chrome EC can be connected by different types of bus like LPC / I2C / SPI, and the current implementation is only for LPC. To support other types, we must first isolate the LPC protocol stuff and add configuration variable (EC_GOOGLE_CHROMEEC_LPC) to specify bus type.
