MOTIONSENSE_CMD_DUMP is deprecated, replaced with MOTIONSENSE_CMD_GET_DATA Also use vector_3_t instead of x,y,z ectool motionsense commands only work with newer firmware, to handle a dynamic number of sensors. - The host sends the number of sensor it has allocated space for. - If 0, the EC just sends the number of sensors available - Otherwise returns sensor information up to the limit imposed by the host. Remove MOTIONSENSE_GET_STATUS: not needed. It is only useful for LPC, to guarantee atomicity of the data. Remove MOTIONSENSE_GET_DATA: not needed since we increase the version number of MOTIONSENSE command. BUG=chrome-os-partner:31071,chromium:430792 BRANCH=ToT TEST=Compile. On a firmware that support the new command: /usr/sbin/ectool --name=cros_sh motionsense Motion sensing active Sensor 0: 92 15 1030 Sensor 1: -94 -63 718 /usr/sbin/ectool --name=cros_sh motionsense active 0 On a machine with older firmware (samus), check these functions are not working anymore.
