From 94084eea3bd33a8a10b55a9717bd6ba762826323 Mon Sep 17 00:00:00 2001 From: Mario Six Date: Wed, 11 Jan 2017 16:00:53 +0100 Subject: [PATCH] tools: kwbimage: Fix dest addr To enable secure boot, we need to jump back into the BootROM to continue the SoC's boot process instead of letting the SPL load and run the main U-Boot image. But, since the u-boot-spl.img (including the 64 byte header) is loaded by the SoC as the main image, we need to compensate for the header length to get a correct entry point. Thus, we subtract the header size from the destination address, so that the execution address points at the actual entry point of the image. The current boards ignore both parameters anyway, so this change shouldn't concern them.
