There is no such thing as a "consumer API". > 1) Is it true that the so called 'consumer application' can use > this API and remain closed source - if so, where in the license > information is this made clear? I guess you might be referring to standalone applications here. And the licensing for these is described right at the beginning of the license file "COPYING". > 2) Who has agreed (or has to agree) that this is acceptable use? Right in the beginning, when U-Boot (or rathewr "PPCBoot", as it was calkled by then) was basicly written by myself only, I came up with this notion of allowing a certain, well-defined (and pretty strictly restrited) set of closed-source extensions. > It's all very well Rafal adding the code and a 'public' header file with > a BSD license - but surely all of the authors that have contributed to > code accessed through this API would have to consent to these terms. The API code implemented by Rafal (abi/* and examples/abi/*) is *not* part of the exception for standalone programs; instead, it is licensed under GPL. The source code makes this pretty clear. > 3) If presume that we cannot use the GPLv2 glue files in a closed > source application. Correct. > We need to understand these points before we can proceed with code that > interacts with this API. For closed source extensions, your only option is what is available via standalone applications, restricted as it is. Of course you can always reconsider and release your code under GPL - that would be the most natural thing given the fact that you are taking man-years worth of source code for free. > Also, following on from these points, how would we go about extending > the API?

Most probably you will need to include header files in addition to those explicitly allowed in the "COPYING" file. This would require you to release your code under GPL.
