You should create your own board port for this custom 440EP board. > 1.

Yes. I already described how you should handle this DDR initialization in my last mail. Use the common code (cpu/ppc4xx/sdram.c). You probably need to change the CONFIG_SYS_SDRAM_TABLE for your board. Take a look at the p3p440.h header as an example. BTW: SDRAM configuration is a complex matter. You definitely need to take a look at the PPC users manual and the SDRAM datasheet for this.
