As above, this does not look right. ACPI has standard mechanisms for
describing addresses. Making something up like this is not a good idea.

 
I am quite new to ACPI, may I ask you to explain a bit? 

ACPI has standard mechanisms for describing certain resources, and these
should not be described in _DSD. Memory or IO address regions are such
resources (in _CRS, IIRC), and should not be described in _DSD.

Thanks,
Mark.
