About the support of STM32MP15x by ISAR

Hello everyone, 
I am wondering if STM32MP15x is currently supported by ISAR.
It is possible to build an image for it with "bitbake 
mc:stm32mp15x-bullseye:isar-image-base", as there are configurations for it.
However: This image did not boot on the stm in my case, and there is no 
mention of the stm32mp15x in the Getting Started section in the 
user_manual. 
So i would like to know, if anyone has recently tried to run the image on 
the actual hardware, and if perhaps the stm32mp15x was never supported at 
an "out of the box"-level and users are required to make some adjustments.

Building is tested on Isar CI, running is not tested. You may want to test the
original submission:

643ad572 meta-isar: Add OP-TEE to STM32MP15x board

With kind regards,

It was me who once added "support" to Isar for that board as I had it in
hands. At that time, I was looking for a nice demo of integrating TF-A
and OPTEE firmware builds, and the STM was basically working without
some ugly BSP, just mainline. Basically.

I had to debug some stuff upstream as well [1], and it seemed to me that
there was a testing gap against upstream. Might be that something
regressed - or that Isar currently presents versions that contained
regressions meanwhile fixed in newer releases.
