I talked to Marek and his approach is different https://lists.denx.de/pipermail/u-boot/2020-April/406438.html He is adding padding to DTB and based on our chat he wants to touch dtb before this space is allocated. That's why I still don't think that this 4k space is really used anywhere. It means I am heading to v2 where DTB start address should be aligned to start at 64bit aligned address and remove this extra unused space. If someone requires to have more space it should be done by adding padding before DTB is built. What do you think? Thanks, Michal
