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.

We'd like this patch series finally to be merged into mainstream. What
should be done to achieve this goal?
Best regards,
