Hi Andre, as this patch has been delegated to you, I would like to mention, that this patch is superseding the patch https://patchwork.ozlabs.org/project/uboot/patch/20220330204543.3790-1-macroalph...@gmail.com/ raised by Chris Morgan.
It should solve the issue in general and does not require to revert to the former DMA implementation. Kind regards Markus
