From 99f1b222339d6eee1c65e04ad1def3c866f155b0 Mon Sep 17 00:00:00 2001 From: nyan Date: Sat, 14 May 2005 09:10:02 +0000 Subject: - Move timerreg.h to /include and split i8253 specific defines into i8253reg.h, and add some defines to control a speaker. - Move PPI related defines from i386/isa/spkr.c into ppireg.h and use them. - Move IO_{PPI,TIMER} defines into ppireg.h and timerreg.h respectively. - Use isa/isareg.h rather than /isa/isa.h.
