Re: [Xen-devel] [PATCH 1/4] xen: Correction to module@1 (dom0 kernel) DT node.

Hi Ian,

Why?

The logic I was going for was to reduce duplicate code/entries in the
DT, and if I read docs/misc/arm/device-tree/booting.txt, the fact that
we have xen,xen-bootargs but no xen,dom0-bootargs then bootargs added
further down in Makefile.am will be used.

Is this not correct or not preferred for some reason?
