can you be more specific with what "does not work properly"? is Linux
then only able to use 2GB or is there any other problem?

overall this sounds like a bug in the vendor u-boot to me
I don't see that we have any other Amlogic .dts which needs this hack,
so I'd like to hear the feedback from the device-tree maintainers (for
example Rob) as well


Best regards,
