.SH "NAME"
superhyway_add_device \- Add a SuperHyway module
.SH "SYNOPSIS"
.HP \w'int\ superhyway_add_device('u
.BI "int superhyway_add_device(unsigned\ long\ " "base" ", struct\ superhyway_device\ *\ " "sdev" ", struct\ superhyway_bus\ *\ " "bus" ");"
.SH "ARGUMENTS"
.PP
\fIbase\fR
.RS 4
Physical address where module is mapped\&.
.RE
.PP
\fIsdev\fR
.RS 4
SuperHyway device to add, or NULL to allocate a new one\&.
.RE
.PP
\fIbus\fR
.RS 4
Bus where SuperHyway module resides\&.
.RE
.SH "DESCRIPTION"
.PP
This is responsible for adding a new SuperHyway module\&. This sets up a new struct superhyway_device for the module being added if
\fIsdev\fR
== NULL\&.
.PP
Devices are initially added in the order that they are scanned (from the top\-down of the memory map), and are assigned an ID based on the order that they are added\&. Any manual addition of a module will thus get the ID after the devices already discovered regardless of where it resides in memory\&.
.PP
Further work can and should be done in
\fBsuperhyway_scan_bus\fR, to be sure that any new modules are properly discovered and subsequently registered\&.
