[U-Boot] exports.h and the GPL

[Michael Walle]

Hi,

As far as i know applications can use functions defined in exports.h without 
being licensed under the GPL.

Who is responsible to define which functions are exported? Are the currently 
exported functions the only ones available to closed source applications or is 
it possible to add further ones which are needed.

Functions may need arguments which are pointers to some structures. These 
structures are likely be defined in some GPL'ed header file and must not be 
used, i guess? So the exported functions must only use integral data types, 
opaque pointers and structures which are not defined in a GPL'ed header file.

I'm aware of the fact that I won't get any legal advice, I'm just asking for 
your opinions.
