[Bug 2004495] Re: Add support for the NXP S32G274A-RDB2 board

[Isaac True]

Hi Loïc,

Yes I've tested the version in the debdiff (3.106ubuntu9) on the target
device (NXP S32G274A-RDB2 reference board aka S32G-VNP-RDB2:
https://www.nxp.com/design/designs/s32g2-vehicle-networking-reference-
design:S32G-VNP-RDB2) running 22.04.

Here's the output of the test:

Title:
  Add support for the NXP S32G274A-RDB2 board

Status in flash-kernel package in Ubuntu:
  Triaged

Bug description:
  I've created a debdiff which adds support for the NXP S32G274A-RDB2
  reference board for the S32G2 SoC. The added fit image template
  (its/arm64/image-nxp-s32.its) can also be used for other boards in the
  S32 family, which may be added in the future.

  This is a development board for NXP's automotive platform with a
  specific and custom BSP (https://github.com/nxp-auto-linux/). The
  device tree and support for the board is not (yet) in the mainline
  kernel, and the board is not supported by upstream U-Boot. In order to
  achieve the best compatibility with the custom U-Boot implementation
  required to boot this board, this patch instructs flash-kernel to only
  generate the fit image and place it in /boot/firmware/fitImage,
  without generating a boot script.
