this is an atempt to make the export of functions typesafe. I replaced the jumptable void ** by a struct (jt_funcs) with function pointers. The EXPORT_FUNC macro now has 3 fixed parameters and one variadic parameter The first is the name of the exported function, the rest of the parameters are used to format a functionpointer in the jumptable, the EXPORT_FUNC macros are expanded three times, 1. to declare the members of the struct 2. to initialize the structmember pointers 3. to call the functions in stubs.c Signed-off-by: Martin Dorwig <dorwig@tetronik.com> Acked-by: Simon Glass <sjg@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org> (resending to the list since my tweaks are not quite trivial)
