[Bug 1931987] Re: [SRU] Creating FIT images is not supported

[Alfonso Sanchez-Beato]

I have verified in focal. Installation generated FIT images on my Kria
system, and reboot was successful. I cannot verify on hirsute though as
I do not have a Kria image for that Ubuntu version.

$ apt policy flash-kernel
flash-kernel:
  Installed: 3.103ubuntu1~20.04.3

Title:
  [SRU] Creating FIT images is not supported

Status in flash-kernel package in Ubuntu:
  Fix Released
Status in flash-kernel source package in Focal:
  Fix Committed
Status in flash-kernel source package in Hirsute:
  Fix Committed

Bug description:
  [Impact]

  flash-kernel does currently not support creating FIT images. There are
  some platforms where this is preferred, for instance for the Kria SOM
  platform.

  This have been just fixed in flash-kernel 3.104ubuntu4 in impish (dev)
  (LP: #1931278), and we would like this ported back to hirsute/focal to
  support Kria SOM platform in focal.

  [Test Plan]

  For testing, a Kria SOM device is needed. By install flash-kernel with
  the fix, a file in path /boot/firmware/image.fit will be created, and
  the system should be able to boot.

  [Where problems could occur]

  The change adds new functionality which should not interfere with the
  previous one. However, there is some small potential for a regression
  happening. If that is the case, some hardware platforms that use
  flash-kernel might not be able to update the bootloader or will break
  it, making the system unable to boot.

  [Other Info]

  See LP: #1931278
