Ok, I had already read both of those posts and when I read "design" I
was thinking that Android Fastboot exists and the feature list is
already set as is the wire protocol, so I don't see that we have a lot
of flexibility in those areas.  The only design I see that is up for
definition is how it can be implemented in U-Boot, that was why I
brought up sharing with DFU.

I will follow up in a separate email with summary design docs of what
fastboot is including what the wire protocol is and what services it
needs from the environment it is running in.  Along with this I will
have pointers to more detailed docs.

Does that sound reasonable?

Thanks for your patience,
John
