+/* orinoco_tmd.c |
+ * |
+ * Driver for Prism II devices which would usually be driven by orinoco_cs, |
+ * but are connected to the PCI bus by a TMD7160. |

+ * The actual driving is done by main.c, this is just resource |
+ * allocation stuff. |
+ * |
+ * 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. |
+ * |
+ * Pheecom sells cards with the TMD chip as "ASIC version" |
