+ * 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.
