arm: socfpga: clock: Clean up pll_config.h Extract the clock configuration horribleness caused by pll_config.h in the following manner. First of all, introduce a few new accessors which return values of various clocks used in clock_manager.c and use them in clock_manager.c . These accessors replace those few macros which came from pll_config.h originally. Also introduce an accessor which returns the struct cm_config default configuration for the clock manager used in SPL. The accessors are implemented in a board-specific wrap_pll_config.c file, whose sole purpose is to include the qts-generated pll_config.h and provide only the necessary values to the clock manager. The purpose of this design is to limit the scope of inclusion for the pll_config.h , which thus far was included build-wide and poluted the namespace. With this change, the inclusion is limited to just the new wrap_pll_config.c file, which in turn provides three simple functions for the clock_manager.c to use.

arm: socfpga: Move wrappers into platform directory Move the wrappers for QTS-generated files into platform directory out of the board directory. The trick here is to add -I to CFLAGS such that it points to the board directory in source tree and thus the qts/ directory there is still reachable. Signed-off-by: Marek Vasut <marex@denx.de>
