bug - bootflow: grub efi crashes when bootflow selected explicitly

[Shantur Rathore]

Hi all,

I am facing an issue with bootflow where grub efi crashes only when
bootflow is selected manually.

Board - RockPro64
OS - Armbian Bookworm CLI
U-boot : 2024.01-rc2
Built and installed in SPI
Boot Device = USB drive connected to USB 2.0 port

Success scenario :

=> setenv boot_targets usb
=> setenv bootmeths efi
=> bootflow scan -lb

Grub loads and Linux boots

I am unable to figure out what is the difference between the 2 ways of booting.

Thanks for your help.
