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.
