Hi Phillippe,

Yeah, I forgot to fill my example. Thanks for the catch.

It is exactly as Bob mentioned, #include MACRO(xxx.h).

There are silicon code use macro to separate definitions, and use the approach to reuse code. Like:
#define PATH(x) <silicon1/x.h> // in platform 1
#define PATH(x) <silicon2/x.h> // in platform 2
#include PATH(abc.h)   // in common code
