U-Boot is not a standard application that runs under control of a general purpose OS, but it's a boot loader that lives in a very restricted, simple environment. As such, we cannot use the standard C library (glibc). Instead, U-Boot is self-contained and includes everything it needs, and nothing more. <stdio.h> is a header file that is provided by glibc - it cannot be used with U-Boot as U-Boot doesn't provide the context needed for such a complex library like glibc. I'm not sure why you would want to include <stdio.h> - it is not needed in U-Boot context. Please look around in the existing code how things are set up in U-Boot. This is NOT like developing a user space application under Linux. It is even more restricted than programming Linux kernel code (and in Linux kernel code you cannot include <stdio.h> either).
