In order to finish moving this symbol to Kconfig for all platforms, we need to do a few more things. First, for all platforms that define this to a function, introduce CONFIG_DYNAMIC_SYS_CLK_FREQ, similar to CONFIG_DYNAMIC_DDR_CLK_FREQ and populate clock_legacy.h. This entails also switching all users from CONFIG_SYS_CLK_FREQ to get_board_sys_clk() and updating a few preprocessor tests. With that done, all platforms that define a value here can be converted to Kconfig, and a fall-back of zero is sufficiently safe to use (and what is used today in cases where code may or may not have this available). Make sure that code which calls this function includes <clock_legacy.h> to get the prototype. Signed-off-by: Tom Rini <trini@konsulko.com>
