The XTRN_DECLARE_GLOBAL_DATA_PTR declarations in ppc code are permanently commented out, so there are no users for this macro: #if 1 #define DECLARE_GLOBAL_DATA_PTR register volatile gd_t *gd asm ("r2") #else /* We could use plain global data, but the resulting code is bigger */ #define XTRN_DECLARE_GLOBAL_DATA_PTR extern #define DECLARE_GLOBAL_DATA_PTR XTRN_DECLARE_GLOBAL_DATA_PTR \ gd_t *gd #endif
Remove all references to this macro, but add a documentation note regarding the possibility of using plain global data for the GD pointer.
