From 3994d502017a2239e30152d1231843ad05d04a7b Mon Sep 17 00:00:00 2001 From: David Kilroy Date: Thu, 21 Aug 2008 23:27:54 +0100 Subject: orinoco: Invoke firmware download in main driver 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. Signed-off-by: David Kilroy Signed-off-by: John W.
