[Bug 1962289] Re: Mediatek AIoT i500 support

[ethan.hsieh]

@Loïc

I'm working on an image which will support multiple Medaitek AIoT
boards. The dtbo files are for some external components like cameras and
panels. Mediatek would like to have these dtbo files in the fitimage.
These components are optional. When end-users have it, they can enable
it by modifying an u-boot variable.

Pi, zynqmp, and other boards' uboot boot scripts are in flash-kernel.
So, I thought it's the right place for the u-boot boot script.

I suggested the HWE team to add the ITS file into linux package. They
will have an internal discussion for it. If ITS/DTB/DTBO are in the
linux packages, there won't be a dependency issue. I'll get back to you
when I get the feedback from the HWE team.

Thanks~

Title:
  Mediatek AIoT i500 support

Status in flash-kernel package in Ubuntu:
  New

Bug description:
  [Impact]
  Add Mediatek AIoT i500 support

  [Test Plan]
  Install the test flash-kernel package with the fix, a file in path Boot-FIT-Path will be created, and the system should be able to boot.
  Test cases:
  1. jammy + Xilinx Kria board: Pass
  2. focal + Mediatek AIoT i500 board: Pass

  [Where problems could occur]
  The fix contains
  1 Add DB entry for Mediatek AIoT i500 board
  Just add a new board to db. There will not be any regression.
  2 Add "kernel_ver" value for the ITS file which includes dts coming from linux package.
  Only Xilinx and Mediatek AIoT board will call mkimage_fit. And, Medaitek AIoT board's dtbs come from linux packages. There will not be any regression.
