On most Freescale 85xx boards, the CONFIG_SYS_CLK_FREQ and CONFIG_DDR_CLK_FREQ macros are defined like this:
Like what?
This means that in order to use these macros, the callers must have prototypes for the corresponding functions. On 85xx, only speed.c uses these macros, so let's define the prototypes there. This eliminates the need to define the prototypes in the board config files.
It also eliminates the utility of the prototype in making sure usage matches the definition, and requires that the user of the macros provide implementation prerequisites.
