Chromebox ECs performs EFS: verifying firmware before the AP boots. This patch updates host commands which are required for the EFS. The change includes: * Update EC_CMD_FLASH_REGION_INFO to accept EC_FLASH_REGION_UPDATE * Update EC_CMD_VBOOT_HASH to accept EC_VBOOT_HASH_OFFSET_UPDATE When EC_FLASHS_REGION_UPDATE is specified, EC_CMD_FLASH_REGION_INFO returns the slot which currently is not hosting a running RW copy. When EC_VBOOT_HASH_OFFSET_UPDATE is specified, EC_CMD_VBOOT_HASH computs the hash of the update slot. This hash covers the entire region, including the signature at the end. This patch undefines CONFIG_CMD_USBMUX and CONFIG_CMD_TYPEC for gru to create space. BUG=b:65028930 BRANCH=none CQ-DEPEND=CL:648071 TEST=On Fizz, verify: 1. RW_B is old and updated by soft sync. RW_B is activated and executed after reboot. System continues to boot to OS. 2. RW_A is old and updated by soft sync. RW_A is activated and executed after reboot. System continues to boot to OS.
