Hello,

At Yocto Project I sent the upgrade for the 2015.10 release, of U-Boot, however it is failing badly:

Does someone has any idea how to fix it?

The problem is the use of "extern inline" function definitions. GCC 5 defaults to the standard C99 semantics for this whereas earlier versions favoured the historical GNU semantics.

The quick fix is to add the -fgnu89-inline compiler flag which requests the old behaviour.

The proper fix is to replace all "extern inline" with "static inline" which is what they should have been all along.
