Each of these SoCs have different devices, different hardware initialisation methods and, quite likely, different quirks. These functions will abstract out the SoC differences and keep these differences out of the drivers (eg USB init, if_arge, etc.) Added: head/sys/mips/atheros/ar71xx_cpudef.h (contents, props changed) Added: head/sys/mips/atheros/ar71xx_cpudef.h ============================================================================== --- /dev/null 00:00:00 1970 (empty, because file is newly added) +++ head/sys/mips/atheros/ar71xx_cpudef.h Wed Aug 18 08:22:09 2010 (r211447) @@ -0,0 +1,108 @@ +/*- + * Copyright (c) 2010 Adrian Chadd + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
