=> efidebug boot next 0

3. Set the following environment and UEFI boot variables
=> setenv -e -nv -bs -rt -v OsIndications =0x04
- => efidebug boot add 0 Boot0000 virtio 0:1 <capsule_file_name>
+ => efidebug boot add -b 0 Boot0000 virtio 0:1 <capsule_file_name>
=> efidebug boot next 0

Set up boot parameters on your board::
- efidebug boot add 1 HELLO mmc 0:1 /helloworld.efi.signed ""
+ efidebug boot add -b 1 HELLO mmc 0:1 /helloworld.efi.signed ""
Now your board can run the signed image via the boot manager (see below).
