Well, if you're using PPCBoot or U-Boot to boot Linux, what you've done would be enough. OTOH, as you have a new hardware design you should check the SDRAM controller initialization in the bootloader code. It may be sligthly wrong, so the bootloader runs but the OS doesn't, because Linux really stresses out RAM operation in burst mode. (BTW, this is a FAQ, if appliable). Out of curiosity what would be the change required for different FLASH port size again on the kernel side. Look for the MTD parameters in the kernel compilation options.
