Detailed Description

iPXE I/O API

The I/O API provides methods for reading from and writing to memory-mapped and I/O-mapped devices.

The standard methods (readl()/writel() etc.) do not strictly check the type of the address parameter; this is because traditional usage does not necessarily provide the correct pointer type. For example, code written for ISA devices at fixed I/O addresses (such as the keyboard controller) tend to use plain integer constants for the address parameter.
