From: "Edgar E. Iglesias" <edgar.igles...@xilinx.com> Hi,
I've been doing some work on modeling parts of EL2 and 3 + some of the system-wide virtualization features for ARMv8. A lot is missing but I've got a series with enough to for example run KVM A64 guests on top of EL3 firmware inside emulated QEMU A64 VMs. I'm working on cleaning things up and plan to send patches and publish things as I go. This series does a first round of preparations. Most of it has little or no user visible impact as the EL2 and 3 features remain disabled. For the arrayification of the various EL regs that do not exist for EL0, I've used index macros. I don't really have a preference here, so if you have better/less ugly ideas or preferences I'm happy to change the pattern (getters/setters or whatever). Happy to address any comments people may have. Cheers, Edgar Edgar E.
