Thanks!\n\nLinux does this with DTB files in quiet_cmd_wrap_S_dtb:\n\necho '.incbin \"$<\" ';\n\nBut Linux only uses generated files in the build directory, never\nactual source files. The font/splash/EFI .incbin rules are U-Boot\nadditions that aren't in the upstream kbuild. So Linux doesn't have\nthis problem.\n\nRegards,\nSimon","headers":{"Return-Path":"","X-Original-To":"incoming@patchwork.ozlabs.org","Delivered-To":"patchwork-incoming@legolas.ozlabs.org","Authentication-Results":["legolas.ozlabs.org;\n\tdkim=pass (1024-bit key;\n unprotected) header.d=chromium.org header.i=@chromium.org header.a=rsa-sha256\n header.s=google header.b=OqkVUuTs;\n\tdkim-atps=neutral","legolas.ozlabs.org;\n spf=pass (sender SPF authorized) smtp.mailfrom=lists.denx.de\n (client-ip=2a01:238:438b:c500:173d:9f52:ddab:ee01;
