S3C2440 development board LED driver - ioremap mapping

When I first started learning character device drivers, I felt that the most difficult part was the connection between the driver and the underlying hardware. The driver on Linux is based on the operating system and does not directly interact with the underlying hardware, but the driver we write must be able to make
