[U-Boot] [PATCH 0/2] Add support for GCC 5.x for MicroBlaze
This patch series fixes some issues with some MicroBlaze functions and declarations that are not compatible with newer C standards (e.g. C99) this includes the default C standard set by the GCC 5.x compiler (which is gnu11 by default).
This series is split into two patches, the first patch being some code style clean up, followed by the patch that fixes the compatiblity.
Nathan Rossi (2): microblaze: Fix style issues in header files microblaze: Fix C99/gnu99 compatiblity for inline functions

'extern inline' is not portable across various C standards. To ensure compatiblity with various standards/compilers change the functions to static inline. This is a portable construct and serves as a comparable definition to 'extern inline' from the gnu90 standard.
Additionally remove the function prototypes as they are not required due to the functions being declared static and functions are correctly ordered based on dependence.
