17    This is the U-Boot binary, containing relocation information to allow it
18    to relocate itself at runtime. The binary typically includes a device tree
19    blob at the end of it. Use u_boot_nodtb if you want to package the device
20    tree separately.

22    U-Boot can access binman symbols at runtime. See:
