Re: [U-Boot] [RFC PATCH 1/3] sandbox: gpio: WIP add basic driver for simulating GPIOs

[Mike Frysinger]

ignoring the upgrade issues, i think this is useful.  only thing
"missing" is having the pin update state externally, but maybe i'm
crazy in thinking we need that.  it certainly could be done in a
follow up patch once your v2 of this patch gets updated, and once we
actually have a proposed interface that someone was able to make work
(vs us dreaming up something crazy like sockets/files/pipes/etc...).
