Peter Maydell 3df708eb48 hw/arm/virt: add secure memory region and UART
Add a secure memory region to the virt board, which is the
same as the nonsecure memory region except that it also has
a secure-only UART in it. This is only created if the
board is started with the '-machine secure=on' property.

* Emulate a virtual board which works by passing Linux all the information
* it needs about what devices are present via the device tree.
* There are some restrictions about what we can do here:
* + we can only present devices whose Linux drivers will work based
* purely on the device tree with no platform data at all
* + we want to present a very stripped-down minimalist platform,
* both because this reduces the security attack surface from the guest
* and also because it reduces our exposure to being broken when
* the kernel updates its device tree bindings and requires further
* information in a device binding that we aren't providing.
* This is essentially the same approach kvmtool uses.
