[PATCH v2 0/3] arm/arm64: Detect Xen support earlier

[Julien Grall]

Hello,

This small patch series moves the detection of running on Xen earlier. This is
required in order to support earlyprintk via Xen and selecting preferred console.

Actually, the last patch of this patch series adds HVC0 as preferred console
when running on Xen. The patch [1] was previously separetly sent by Ard.

For the maintainers, does this patch series should go in upstream via the ARM
tree or Xen tree?

Regards,
