x86: ivybridge: Provide a dummy SDRAM init for 64-bit We don't support SDRAM init in 64-bit mode since it is essentially impossible to get into that mode before SDRAM set up. Provide dummy functions for now. At some point we will need to pass the SDRAM parameters through from SPL. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
