[Qemu-devel] [PATCH v3 00/32] target-arm: add Security Extensions for CPUs

[Fabian Aggeler]

Hi,

this is round 3 of the Security Extension patches which started with
the TrustZone patchset by Samsung. Many patches were dropped or 
got separated from this patchset. It shows yet another mechanism of
register banking for EL3 running in Aarch32 mode. This version also
conforms better with the ARM ARMv8. The patches got reordered with 
banking related patches at the end. Most of the registers get converted
separately now.

The whole patchset is based on master with Edgar's patches of
yesterday (v2 target-arm: Parts of the Aarch64 EL2/3 exception model)
applied.

Patch 9,10,11 and 12 are added for some more discussion about Edgar's 
patches which break out masking and target_el. Parts of it could 
probably be added to Edgar's patchset. 

v2 -> v3:
* rebased
* reordered
* changed from ARM_FEATURE_SECURITY_EXTENSIONS to ARM_FEATURE_EL3
* renamed tz_cp_reginfo to security_cp_reginfo
* extended arm_is_secure() with EL3 handling
* rewrote nsacr patch
* removed MMU split for secure/nonsecure world
* removed arm_current_sctlr
* new banking scheme

v2: http://lists.gnu.org/archive/html/qemu-devel/2014-05/msg02522.html

Thanks,
Fabian
