The code already looks for "linux,usable-memory" in preference to "reg". Can you use that instead?
Yes, we could set the size of "linux,usable-memory" to zero instead of setting status to "disabled".
I'll send a v5 of this set which drops 1/5 and 2/5. That would be the only difference here.
That would have the advantage that existing kernels already understand it. Another problem with using "status" is we could have device trees out there that have status = disabled and we don't know about it, and by changing the kernel to use that property we break people's systems. Though for memory nodes my guess is that's not true, but you never know ...
