Details:
This patch adds support for a new programmer type - gpio. It uses the Linux
sysfs interface to bitbang GPIO lines. Mostly useful in embedded Linux
systems, where there are a lot of GPIOs available.
To enable it pass the --enable-gpio option to ./configure. Then set the
appropriate GPIO numbers in avrdude.conf.
It is kind of slow, taking ~30s to upload 8K to flash on a 150MHz x86 system.
It will be a lot faster writing directly to the CPU registers, but this way it
works for all processors that have Linux GPIO support implemented.
