From 570c4636808e77a18ccd8865b2654fff08f13328 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Thu, 19 Aug 2021 11:09:37 +0200 Subject: Makefile: Align fit-dtb.blob and u-boot.itb by 64bits Enabling MULTI_DTB_FIT and DTB_RESELECT can end up with multi DTBs in FIT image placed and aligned only by 32bits (4bytes). Based on device tree specification: "Specifically, the memory reservation block shall be aligned to an 8-byte boundary and the structure block to a 4-byte boundary." is 64bit (8bytes) alignment required. That's why make sure that fit-dtb.blob and u-boot.itb as our primary target images for Xilinx ZynqMP are all 64bit aligned.
