From 4b78bb504142ebc97efae6908e666cb0608ebf86 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Tue, 27 Aug 2019 06:24:43 +0000 Subject: [PATCH] tools: imx8m_image: align spl bin image size 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.
