[Qemu-devel] [PATCH v2 0/9] target-arm: EL3 trap support

[Greg Bellows <greg.bellows@linaro.org>]

Initial patchset adding support for trapping to an EL other than EL1.  Support
includes changes to interfaces to allow specification of the target EL.  Also
includes the addition of the ARMv8 CPTR system registers used for controlling
the trapping of features.

---

v1 -> v2
- Removed use of MAX through out the patch when setting target_el
- Updated FP trap support to pass a target exception EL rather than just an
  enable boolean.
- Added utility functions for determining the target exception EL
- Broke up cptr and cpacr access functions
- Added HCPTR CP register entry and HCPTR/CPTR_EL2 zero entries
- Broke out TCR changes into their own patch and added support for handling the
  lack of TTBR1
- Simplified wfx checking
- General comment cleanup
