Hi Pierre-Clément,

Some headers included (possibly indirectly) from .dts files might have U-Boot specific content relying on the __UBOOT__ macro passed to CPP when building C code. In that case, it would be sensible for DTC to see that content instead of the non-U-Boot one. To do so, pass the macro to the pre-processor when generate DTC inputs.
Can you give an example of such a situation?
