Note, JTAG is != serial port. with reference to jflash.c,
the JTAG(PC) will send command to the SA, using Scan path to output the data
to the SA pins, activate the control and data lines to program the flash.
Other methods include programming the FLASH using universal programmer, then
use a flash socket to hold the flash.
Or we can learn from better solutions.
