Firmware download is enabled for Agere in orinoco_cs. Symbol firmware download has been moved out of spectrum_cs into orinoco_cs. Firmware download is not enabled for Intersil. Symbol based firmware is restricted to only download on spectrum_cs based cards. The firmware names are hardcoded for each firmware type.

|

* This driver is modeled after the orinoco_plx driver. The main
|
|
* difference is that the TMD chip has only IO port ranges and doesn't

|
* provide access to the PCMCIA attribute space.
