this is the last piece for getting Layerscape up and running. So far we
started Linux in EL3 which doesn't work at all. This series adds support
for loading and executing the PPA ("Primary Protected Application"). PPA
is a PSCI compliant firmware running in EL3. With this Linux is starting
properly on all cores.
