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
