Hello Wolfgang,
2009/7/6 Wolfgang Denk wd@denx.de:
Dear Jerry Van Baren,
- U-Boot currently has an explicit license to run "stand alone
applications" that have a GPL-incompatible license.
Thanks for mentioning this. But this is explicitly restricted to "stand alone applications", with a pretty tightly limited set of functions exported to such code. It is not intended to be extended into something like loadable modules that can access much more of U-Boot's internal code.
AFAIK this limitation of extension is not stated anywhere in the documentation that is delivered with U-boot. (If I am wrong, please point me to the location where this is stated)
So, I guess every user of U-boot is allowed to extend that interface to even the complete symbol map of U-boot, without doing anything in conflict with the license. You can now say it is not intended, but it is not restricted.
Kind Regards,
Remy
