[avrdude-dev] support for bitbanging GPIO lines through /sys/class/gpio

[Radoslav Kolev]

Hello,

I have added support for using GPIO lines as a programmer. Many SOCs
have GPIO lines and the standard way to use them from userpace is
through the sysfs gpio interface, so this should be quite universal,
even if a bit slow.

I have tested this on a Bifferboard (http://bifferos.bizhat.com/)
which has a 150MHz x86 CPU and writing 8K to the flash of an AtMega
takes around 30 seconds.

I am sending in a patch against avrdude-5.10, in case someone finds this useful.

Best regards,
Radoslav Kolev
