I don't really care all that much about that, but if we need modifications to run Windows (and nothing prevents that from working with Linux), then should we try to change the upstream defaults? But for me, I'd be happy with just the build instructions you have, and no binaries/license, in edk2-platforms/Platform/RaspberryPi/RPi3/Arm-Tf/, with the user having to drop in their own binaries. > For the record, there's a readme located in the directory where the ATF > binaries are provided, that has the full build command we used, as well as > the description of the memory mapping.
