When U-Boot is running from EFI some of the x86 init is replaced with EFI-specific init. For example, since DRAM has already been set up, we only need to find it, not init it. Add these functions so that boards can easily allow booting from EFI if required. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
