U-Boot has imported various source files from other projects,
mostly Linux.
Something like
#ifdef __UBOOT__
[ modification for U-Boot ]
#else
[ original code ]
#endif
is an often used strategy for clarification of adjusted parts,
that is, easier re-sync in future.
Instead of defining __UBOOT__ in each source file,
passing it from the top Makefile would be easier.
