This heavy-handed approach of imposing custom DTC build on everyone because of a feature noone uses is awful and I disagree with it. If there is a version check for DTC for builds with and without DTO, fine, I can live with that. But bundling DTC only because of unused functionality, NAK. -- Best regards, Marek Vasut _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
