Module Name: src
Committed By: mbalmer
Date: Fri Aug 12 08:00:53 UTC 2011
Modified Files:
src/distrib/sets/lists/modules: md.evbppc mi
src/sys/dev/gpio: gpio.c gpiosim.c gpiovar.h
src/sys/modules: Makefile
Added Files:
src/sys/modules/gpio: Makefile gpio.ioconf
src/sys/modules/gpiosim: Makefile
Log Message:
gpio(4) and gpiosim(4) can now be built and used as modules. While here,
make some functions static.
