Hi Thomas,

This patch series adds support for cfe_die() which can be used during
early platform initialization when we do not yet have a valid DTB to
infer an earlycon console from. This is useful while bringing up new
platforms/DTBs as well.

Thanks!

Changes in v2:

- ensure that we do not break multi-CPU builds by reading the CPU's PrID
  to perform the appropriate XKS01 disabling before handing over to CFE
