Yes this is very useful for that. A large number of nodes can be attached to one host. Also there must be a lot of people whose only jtag adapter is a raspberry pi, so it makes sense that we probably want to support that.

In fact it might also be worth adding bcm2835gpio in addition to sysfsgpio. It's specific to raspberry pi but presumably it's faster. I don't know that it is but I'm recompiling openocd with sysfsgpio to find out.

What do you think about adding an option to set RST=-1 to disable use of the reset pin? I don't usually bother connecting it when I'm only flashing a board.
