From 0fec65130b9f11a73d74f47025491f97f82ba070 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Tue, 5 May 2015 10:06:06 -0700 Subject: arcnet: com20020: Use arcnet_ routines Simplify and make consistent the current uses of inb/outb by using the newly introduced arcnet_ equivalents. o Add new #defines for register offsets There is an register offset, 8, that is unnamed and used as-is. o Remove old #defines that included the ioaddr o Remove obfuscating macros by expanding them in-place where appropriate o Create static inline com20020_set_subaddress for the SET_SUBADR macro There is an unused arcnet config entry CONFIGSA100_CT6001 which added a special #define BUS_ALIGN which was introduced but never used in fullhist git tree commit 22cfce4b82b0 ("[ARCNET]: Fixes.") in Nov 2004 for Linux v2.6.10. This BUS_ALIGN #define tries to allow 8 bit devices to work on a 16 bit bus by aligning addresses to 16 bit boundaries. Move this currently unused CONFIG_SA1100_CT6001 BUS_ALIGN macro from com20020.h to arcdevice.h.
