xous-core/emulation/peripherals/keyrom.cs
Sean Cross 317f3136aa emulation: complete initial emulation of spinor/flash 
Emulate both the SPINOR block as well as the OSPI flash attached to it.

With this change, the PDDB can now be initialized and resets itself
properly. Additionally, data persists across virtual reboots.

Data does not persist across runs of the emulator. That will follow in
an upcoming patch.
