Do you know why the patch has been left (as far as I can see) without further action?
I don't know. I assume the maintainer is very busy or has missed it. I was planning to do a resend in the next few weeks.
BTW, I applied it to current master, compiled approximately following https://docs.u-boot.org/en/latest/board/nxp/imx8mp_evk.html and tried to use it on Debix Model A. U-Boot starts but cannot find the partition table on the SD card:

When I use an old U-Boot blob provided by Debix, it boots fine from the same SD card. The SD card contains a Fedora aarch64 image with a msdos partition table.
Do you know what could be wrong?
Interesting. I don't have a clue yet,. but let me give it a try and come back to you. Where can I download the Fedora aarch64 image you mentioned above?
I flashed the image freshly, to another SD card, and it boots happily. So I can confirm your patch works. :-)
I don't know what's wrong with the partition table on the original SD card. I manipulated with the partitions and their properties a bit before but parted or the other versions of U-Boot I tried don't report any problem. Maybe the U-Boot version from master that I happened to compile does something differently. Anyway, it's unlikely to be related to this patch as it boots fine on a freshly flashed SD card.
Thank you for the patch, hopefully it'll get merged.
