While it’s not directly related to this patch, we should clearly state that the U-Boot code base (with the possible exception of the tools/ directory, which I have started touching here) has _implicitly_ moved to GNU11 (yes, even newer than C99), when be upgraded beyond GCC 5.
For reference, see the "Default standard is now GNU11” section at https://gcc.gnu.org/gcc-5/porting_to.html
Do we want to (a) document this somewhere (which file in doc/ would be appropriate?) (b) explicitly set the “--std=“ flag to make sure that people (and their compilers) are aware of this?
For the record, I don't see anything here as a problem. I did half suggest, and did reviewed-by just spelling out GNU11. So long as that isn't a problem for clang-5, I don't think this is a problem. The "$X is a warning" are things we've had to long since clean up. This is also not me suggesting that we make use of any particular new language features.
