The "jump table provided by U-Boot exactly for this purpose" is the list of functions exported through the "include/_exports.h" header file. Only these functions are available from standalone programs without linking against any of the U-Boot provided libraries. If your program links and runs fine using only these functions then you are free to license your standalone application whatever you like; if you need to link against any of the U-Boot libraries then you must release your code under GPL. > 2.

Well, the file "COPYING" explicitly mentions the header files where the situations is clear: > The header files "include/image.h" and "include/asm-*/u-boot.h" > define interfaces to U-Boot.

The fact that these files are explicitly mentioned *not* to make yoru code a Derived Work should make clear that all other header files do, or at least might do, so you better not include these in a standalone application you don't intend to release under GPL. If you do, you better check with your legal department, and rely on what they tell you. Note that I just wouldn't do that.
