Dear Graeme Russ,

The idea would be to reduce the license text in U-Boot to just the SPDX-License-Identifier, but we should also provide details on where the original file came from. I guess this is the next (harder) step.
Full agreement here. But actually this has been a requirement for some time already, see section "Attributing Code, Copyrights, Signing" (and especially bullet # 4 there) at [1]

OK, this records such information in the git history, but that's better than nothing.
Wolfgang: How do you think this should be best handled? I still haven't found a definitive reference for the use of SPDX-License-Identifier - are there other identifiers which can be used to specify the original source of the file?
Well, in my (definitely limited) understanding of the SPDX specification the "sourceInfo" property appears to be the best fit for such information - so we could for example define entries "SPDX-Source-Info" which could contain this - in a T.B.D. format ?
Best regards,
Wolfgang Denk
