  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:

  26     in the binman README for more information.
