I'd also add similar comment to DT file to prevent people from trying
to "fix" this in the future.

Also, this change is going to break QEMU's mapping found here:

https://git.qemu.org/?p=qemu.git;a=blob;f=hw/arm/fsl-imx7.c;h=d5e26855a552e2d52b91f0435a607fae2f88456b;hb=HEAD#l464

any change you are planning to make the change there as well?

Thanks,
Andrey Smirnov
