- implement all of the init, init early, and setup arch routines in the shared source file for the MPC512x PowerPC platform, and make all MPC512x based boards (ADS, PDM, generic) use those common routines - remove declarations from header files for routines which aren't referenced from external callers any longer this modification concentrates knowledge about the optional FSL DIU support in one spot within the shared code, and makes all boards benefit transparently from future improvements in the shared platform code the change does not modify any behaviour but preserves all code paths Signed-off-by: Gerhard Sittig <gsi@denx.de> Signed-off-by: Anatolij Gustschin <agust@denx.de>
