You can run "make -j BOARD=it8380dev" to build ec.bin
and flash the ec.bin via
"sudo ./build/it8380dev/util/iteflash -w ./build/it8380dev/ec.bin"

1. change I2C frequency to 400K.
2. include the support for other it83xx series.
3. add "chip erase" command if the erase size equals to
flash's physical size.
4. remove 50h command.
5. always check write enable bit of the status reg, after
write enable command.
