+
+ARM:asm:io.h use static inline
+
+When compiling u-boot with W=1 the extern inline void for
+read* is likely causing the most noise. gcc / clang will
+warn there is never a actual declaration for these functions.
+Instead of declaring these extern make them static inline so
+it is actually declared.
