- dtc_cpp
- This is just like dtc as describe above, except that the C pre-
- processor is invoked upon the .dtsp file before compiling the result
- with dtc.
-
- In order for build dependencies to work, all files compiled using
- dtc_cpp must use the C pre-processor's #include functionality and not
- dtc's /include/ functionality.
-
- Using the C pre-processor allows use of #define to create named
- constants. In turn, the #defines will typically appear in a header
- file, which may be shared with regular C code. Since the dtc language
- represents a data structure rather than code in C syntax, similar
- restrictions are placed on a header file included by a device tree
- file as for a header file included by an assembly language file.
- In particular, the C pre-processor is passed -x assembler-with-cpp,
- which sets macro __ASSEMBLY__. __DTS__ is also set. These allow header
- files to restrict their content to that compatible with device tree
- source.
-
- A central rule exists to create $(obj)/%.dtb from $(src)/%.dtsp;
- architecture Makefiles do no need to explicitly write out that rule.
