Hi Alice,

This is unacceptable. Had I known this series was doing this I would
have NAK'd it. There was no mention in the commit log that this would
drop support for A0. There are many vendors like myself who have A0
silicon evk's that will likely never get upgraded and should not
become bricks.

We need to at least know how to get back to working boot firmware for
A0. I would be fine if there was just a Kconfig to select A0.

Yes, I tried mx95a0-ahab-container.img but I think you need to be more
specific with the 'older imx-oei' - there are obviously patches in the
OEI's that also drop support for A0. Regardless, I've gone back to the
OEI that I was using previously (lf-6.6.52-2.2.0) and I'm still not
booting and reverting commit 9936724aa9b ("imx95_evk: Add i.MX95 B0
support") didn't get me booting either. I'm still trying to figure it
out.

Best Regards,

Tim
