Public bug reported:
[Impact]
Flexible and powerful format based on Flattened Image Tree -- FIT (similar
to Flattened Device Tree). It allows the use of images with multiple
components (several kernels, ramdisks, etc.), with contents protected by
SHA1, MD5 or CRC32, etc.
More details:
https://gitlab.denx.de/u-boot/u-boot/blob/master/doc/uImage.FIT/howto.txt
The packaging changes will add support for building a FIT kernel binary
blob which can be subsequently signed. These FIT-signed kernels will be
consumed by snapcraft recipes to build kernel snaps for platforms with
U-Boot bootloader enforcing secure boot.
[Regression Potential]
Minimal.
This bug is for tracking purposes only, do not triage.
