Maybe EPROM is not Broadcom specific, but I suspect the content we deal with in bcmai/axi is Broadcom specific. I didn't see any notes of manuf/id/rev/class we deal with. So I guess everything *we* (out driver) read from EPROM is Bcm specific. -- RafaÅ -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
