Peter Maydell d9f43babb9 Documentation: dt: Add bindings for Secure-only devices ... The existing device tree bindings assume that we are only trying to describe a single address space with a device tree (for ARM, either the Normal or the Secure world). Some uses for device tree need to describe both Normal and Secure worlds in a single device tree. Add documentation of how to do this, by adding extra properties which describe when a device appears differently in the two worlds or when it only appears in one of them. The binding describes the general principles for adding new properties describing the secure world, but for now we only need a single new property, "secure-status", which can be used to annotate devices to indicate that they are only visible in one of the two worlds. The primary expected use of this binding is for a virtual machine like QEMU to describe the VM layout to a TrustZone aware firmware (which would then use the secure-only devices itself, and pass the DT on to a kernel running in the non-secure world, which ignores the secure-only devices and uses the rest).
