i couldnt seem to find anyone else who had imported asm/gpio.h yet, but i 
guess  was looking in the wrong place.  i have generic GPIO implementations 
pending for:
	- command line 'gpio' to toggle/set/clear pins
	- soft i2c via gpio
	- i had a status led gpio, but i'll convert to your version
	- examples for doing parallel flash with GPIO-assisted address lines

i'll try and generalize them a bit more and send thing out.  not sure if 
you'll find any of these useful though.
