superhyway_add_device — Add a SuperHyway module
int superhyway_add_device ( | unsigned long base, |
| struct superhyway_device * sdev, | |
struct superhyway_bus * bus); |
basePhysical address where module is mapped.
sdevSuperHyway device to add, or NULL to allocate a new one.
busBus where SuperHyway module resides.
This is responsible for adding a new SuperHyway module. This sets up a new
struct superhyway_device for the module being added if sdev == NULL.
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.
Further work can and should be done in superhyway_scan_bus, to be sure
that any new modules are properly discovered and subsequently registered.
