If you want a good validation it should be done in a separate function taking others aspects into account. But since it doesn't affect my area of interest in U-Boot, I won't prevent you from doing this way, it's up to the U-Boot maintainers how to proceed with it. -- With Best Regards, Andy Shevchenko
