By the way, may I suggest that, in the long run, this kind of features
should be handled by the intermediate system that implements the boot
loader GUI and kexec's to the real system.
There are a number of reasons:
- the number of possible interactions (buttons) is very limited
- magic buttons tend to be confusing (see how complex things are with
GTA02 under u-boot for boot menu and NOR)
- on GTA02, AUX is a dangerous button, so it's better if we don't use
it for too much
Implementing this in the intermediate system doesn't conflict with what
you're doing, but I think it would be good to direct efforts more
towards a long-term solution than tweaking Qi. Of course, hacking boot
loaders is fun ;-)
