u-boot-efi-dtb - 2 main

This package automatically create and keep up-to-date a dtb/ directory on the
EFI System Partition (ESP) using the device tree blobs (DTBs) from the
installed linux-image packages. When U-Boot is running in UEFI mode, it can
then load the appropriate DTB for the board during the distroboot process.
This ensures that the DTB passed to the kernel is kept up-to-date, even when
using an older U-Boot versions.
