That is something I very specifically avoided in the kernel Makefiles. If we did allow this, then DTs could start including arbitrary U-Boot header files, rather than just header files intended to be used in DT bindings, and that would then make the DT files used in U-Boot not portable to the Linux kernel, or any standalone DT file repository which may appear. Instead, let's create a standalone root directory for the DT include files, and add that to the DT header path. We can add this DT-specific include path to the include patch for U-Boot C code if needed. Perhaps we can create a top-level dt/include/ or device-tree/include directory for this? _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
