The loader for the DDR firmware in drivers/ddr/imx/imx8m/helper.c uses a 4-byte-aligned address to load the firmware. In cases where OF is enabled in SPL the dtb will be appended to the SPL binary and can result in a binary that is not aligned correctly. If OF is not enabled in SPL, `_end` is already aligned correctly, but this patch does not hurt. To ensure the correct alignment we use dd to create a temporary file u-boot-spl-pad.bin with the correct padding.
