[Qemu-devel] [PATCH v2 0/8] arm: Steps towards EL2 support round 4

["Edgar E. Iglesias" <edgar.iglesias@gmail.com>]

From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com>

Hi,

This is another series with small steps towards EL2 emulation.

Patch 1 is a fix to allow easier testing of EL3-less cores.
Patches 2 and on add regs and a few small steps towards 2-stage MMU.

Comments welcome!

Best regards,
Edgar

v1 -> v2:
* Add fix for gracefully handling missing has_el2 CPU props
* Dropped suppress of TTBR1 for S2 (unneeded)
* Comment on vttbr_write TLB flush
* Mark second instance of VTTBR as ALIAS
* Split the active aa32ns_aa64any into separate AA32/AA64 registrations to
  allow the AA64 one to avoid .access checks
* VTCR does not need TLB flushes
* Various CP_CONST/resetvalue=0 instead of writefns/readfns
* Fix VMPIDR el2 vs el1 typo
* Fix VMPIDR reset value
* Fix spelling of suppress in commit message
