Detailed Description

console driver for S3C2400 UARTs

This driver uses the shared console driver in bsps/shared/dev/serial/legacy-console.c

If you want the driver to be interrupt driven, you need to write the ISR, and in the ISR insert the chars into termios's queue.

Variable Documentation

Console_Configuration_Count

unsigned long Console_Configuration_Count = NUM_DEVS

The number of serial ports defined in Console_Configuration_Ports

Console_Configuration_Ports
