* iPXE sanboot API
|
|
*
|
|
* The sanboot API provides methods for hooking, unhooking,
|
|
* describing, and booting from SAN 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.
