It is often inconvenient to place device tree files in the same directory as their includes, or to specify the full path to include files. An example of this is in U-Boot where we have a .dtsi file for each SOC type, and this is included by the board .dts file. We need to either use a mechanism like: /include/ ARCH_CPU_DTS with sed or cpp to perform the replacement with the correct path, or we must specify the full path in the file: /include/ "../../arch/arm/dts/tegra20.dtsi" The first option is not desirable since it requires anyone compiling the file to first pre-process it. The second is not desirable since it introduces a path which is project-specific into a file which is supposed to be a hardware description. For example Linux and U-Boot are unlikely to put these include files in the same place. It is much more convenient to specify the search patch on the command line as is done with C pre-processors, for example. Introduce a -i option to add to the list of search paths used to find source and include files. We cannot use -I as it is already in use. Other suggestions welcome.
