Looking a little closer, the place where the generic list of matches and
attributes doesn't work well is when trying to deal with the no-memory-wc
property available only in mmio-sram nodes.

We'd really need an mmio-sram specific check in that case. Either
explicitely open coded in domain_build.c or something along the lines
f the .map method. Or did you have other ideas in mind?

How about extending the function dt_match_node and the structure dt_device_match to check the existence (or not) of a property?
