ughh..

Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt is
not converted to yaml.

Rob, Arnd,

I am considering to pick this series up this friday given the scale
of other platforms that are using the same property and since I see
for example commit 0fe0fbc867115659bbd9a0ab107d1fe9bcc432e8 (MIPS)
in next-20210616. Unfortunately [1] does'nt give me much precedence
either in immediate recent history.

Let me know if you think we should wait on this.
