[Qemu-devel] [PATCH v2 00/16] target-arm: Add GICv1/SecExt and GICv2/Grouping

[Greg Bellows]

This patch series adds ARM GICv1 and GICv2 security extension support.  As a
result GIC interrupt grouping and FIQ enablement have also been added.  FIQ
enablement is limited to ARM the ARM vexpress and virt machines.

At the current moment, the security extension capability is not enabled as it
depends on ARM secure address space support for proper operation.  Instead,
secure checks are hardwired as non-secure.

v1 -> v2
- Fixed GIC_SET macro logic for group 0 and 1
- Fixed gic_update to use correct GIC_CTLR bit for group 1
- Reworked gic_set/get_cpu_control to better handle non-security extension case
  for GICv1.
- Fixed various BPR read/write issues.
- Fixed EOIR ackctl issue.
- Fixed issue with gic_acknowledge not properly checking secure state.
- Fixed gic_update use of incorrect bit to check cpu_control group 1
  enablement.
- Added clarifying comments
- Various fixes based on initial version review comments (see individual
  patches for details).
