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.
