compatible parameter origins and overriding

After Qsys system generation:

- What are the origins of "compatible" parameter (later used in Device Tree Blob) in generated .sopcifo/.xml files?

- And is it possible to override this parameter using Quartus tools?

    Device Tree related information in .sopcinfo file is set during qsys - generate process. qsys searches ip core's directory for *_hw.tcl script, where device tree related commands may reside.

    for example:

    set_module_assignment embeddedsw.dts.vendor "ALTR"

    set_module_assignment embeddedsw.dts.group "msgdma"

    set_module_assignment embeddedsw.dts.name "msgdma-dispatcher"

    set_module_assignment embeddedsw.dts.compatible "ALTR,msgdma-dispatcher-1.0"

    overriding can be achieved with editing these scripts
