Yes that's right, but if BLOBLIST_SIZE_RELOC is used, U-Boot may relocate it. > The reason I ask is that I'm preparing some patches to add bloblist support > to vexpress64, and I'm looking to configure this platform without specifying > BLOBLIST_ADDR or BLOBLIST_SIZE (i.e., automatically detect these).
