Now that we have 3 boards for the MPC512x it turns out that they all use the very same fixed_sdram() code. This patch factors out this common code into cpu/mpc512x/fixed_sdram.c and adds a new header file, include/asm-ppc/mpc512x.h, with some macros, inline functions and prototype definitions specific to MPC512x systems.
