PCHG: Support firmware update
This patch adds EC_CMD_PCHG_UPDATE, which allows the host to update
firmware of ctn730 via I2C.
An updater (e.g. ectool) is expected to issue EC_PCHG_UPDATE_CMD_OPEN,
multiple EC_PCHG_UPDATE_CMD_WRITEs, then EC_PCHG_UPDATE_CLOSE. Each
sub-command completion is notified to the host via EC_MKBP_EVENT_PCHG.
An updater is supposed to wait for the previous sub-command to
complete before proceeding to the next.
Example:
localhost ~ # ectool pchg 0
State: DOWNLOAD (6)
FW Version: 0x104
localhost ~ # ectool pchg 0 update 0x207000 0x105 /path/to/image.bin
Update file /path/to/image.bin (85632 bytes) is opened.
