Adam Joseph 8485bfc9bf arm-trusted-firmware: unfree only if hdcp.bin used; otherwise delete it ... The `unfreeIncludeHDCPBlob` parameter was introduced as a result of this reviewer request: https://github.com/NixOS/nixpkgs/issues/148890#issuecomment-1032002903 The default value `unfreeIncludeHDCPBlob?true` causes a change in the `meta.license` field for all of the subpackages within `pkgs/misc/arm-trusted-firmware/`, and results in them needing `NIXPKGS_ALLOW_NONFREE=1`. For non-Rockchip platforms the file hdcp.bin does not get included in the output; the blob is for a Synopsys HDCP core that is currently used only by Rockchip (although other companies could license it from Synopsys in the future). Therefore on non-Rockchip we can delete hdcp.bin before building instead of changing the license. This preserves the ability to build them without NIXPKGS_ALLOW_NONFREE=1. Let's do that. Deleting hdcp.bin ensures that we won't be caught by surprise if some future non-Rockchip Arm CPU licenses the same Synopsys HDCP core that Rockchip is using. Use easier-to-follow names for controlling the blob inclusion/exclusion. Also, if the blob is believed to be unnecessary, delete it beforehand so we will know if we were wrong about that belief.
