From: "Yingshiuan Pan" <yingshiuan.pan@xxxxxxxxxxxx> Add documentation for GenieZone(gzvm) node. This node informs gzvm driver to start probing if geniezone hypervisor is available and able to do virtual machine operations. [Reason to use dt solution] - The GenieZone hypervisor serves as a vendor model for facilitating platform virtualization, with an implementation that is independent from Linuxism. - In contrast to the dt solution, our previous approach involved probing via hypercall to determine the existence of our hypervisor. However, this method raised concerns about potentially impacting all systems, including those without the GenieZone hypervisor embedded[ref].
