Yup. I don't want to see skeleton.dtsi reappear, and the necessary
fixups to source files are relatively simple.

Ian, see commit 3ebee5a2e141496b ("arm64: dts: kill skeleton.dtsi") for
the rationale, and hints as to what needs to be fixed up (e.g. if empty
memory nodes are required, there should be a comment as to why).

Perhaps this is a good time to attack the remaining 32-bit skeleton.dtsi
users. I'll take another look come -rc1.

Thanks,
Mark.
