[Qemu-devel] [PATCH v4 00/33] target-arm: add Security Extensions for CPUs

[greg . bellows]

From: Greg Bellows <address@hidden>

Updated Fabian's v3 patchset for review comments.  This patchset includes
changes in support of the security extension on v7 aarch32 with hooks for later
enabling v8 aarch64.

The patches are built upon and therefore dependent on v3 of Xilinx's second 
round of EL2/3 patches.  

Summary of the changes from v3 -> v4:
* Conditionally register security CP registers.
* Fixed various bugs found in review
* Reverted back to EL array-notation in combination with explicit v7 naming
* Add functionality to handle migration of duplicate CP registrations
