[Qemu-devel] [PULL 08/12] arm: xlnx-zynqmp: Preface CPU variables with "apu"

[Peter Maydell]

From: Peter Crosthwaite <address@hidden>

The CPUs currently supported by zynqmp are the APU (application
processing unit) CPUs. There are other CPUs in Zynqmp so unqualified
"cpus" in ambiguous. Preface the variables with "APU" accordingly, to
prepare support adding the RPU (realtime processing unit) processors.
