The names of the carveout regions are derived using the names of the
reserved memory devicetree nodes, which are referenced using the
"memory-region" property. This adds a restriction on the names of said
devicetree nodes, often bearing specific names such as: "vdevbuffer",
"vdev0vring0", "rsc-table", etc... This goes against the devicetree
specification's recommendation, which states that the devicetree node
names should be generic.
No, it does not. Names like rsc-table feels exactly like DT spec is
asking - for a name matching purpose. Are you sure you read the spec?
Fix this by documenting an additional, optional property:
"memory-region-names". This way, the carveout names can use the values
passed via "memory-region-names", while keeping the devicetree node
names of the reserved memory regions generic.
I don't see how anything here is fixed. memory-region-names has nothing
to do with node names.

Best regards,
Krzysztof
