The 16c2550 serial port chip can be used to expand two serial ports. Its operation method and register usage are exactly the same as 8250, so we can use the classic 8250 driver in Linux to drive st16c2550. 8250 the driver remains unchanged. You need to add the 16c2550 initialization code. In the initialization code, you need to set the chip selection and IRQ pin
