[Qemu-devel] [RFC PATCH 00/21] target-arm: add CPU core TrustZone support

[Sergey Fedorov]

This patch set implements a basic support of CPU core TrustZone feature. The
following major functionalities are implemented:
  * CPU monitor mode
  * Separate code translation for each secure state
  * CPACR & NSACR co-processor access control
  * Separate TLB for each secure state
  * Co-processor register banking
  * SMC instruction
  * FIQ/IRQ routing to monitor mode

There is no support for banked co-processor register migration, save/load its
VM state yet. That is an open question how to implement this functionality. Any
suggestions is greatly appreciated.

This patch set is a request for comments for the proof of concept.
