From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com> This patch series adds initial support for Xilinx's Versal SoC. Xilinx is introducing Versal, an adaptive compute acceleration platform (ACAP), built on 7nm FinFET process technology. Versal ACAPs combine Scalar Processing Engines, Adaptable Hardware Engines, and Intelligent Engines with leading-edge memory and interfacing technologies to deliver powerful heterogeneous acceleration for any application. The Versal AI Core series has five devices, offering 128 to 400 AI Engines. The series includes dual-core Arm Cortex-A72 application processors, dual-core Arm Cortex-R5 real-time processors, 256KB of on-chip memory with ECC, more than 1,900 DSP engines optimized for high-precision floating point with low latency. More info can be found here: https://www.xilinx.com/news/press/2018/xilinx-unveils-versal-the-first-in-a-new-category-of-platforms-delivering-rapid-innovation-with-software-programmability-and-scalable-ai-inference.html In QEMU we'd like to have a virtual developer board with the Versal SoC and a selected set of peripherals under the control of QEMU. We'd like to gradually extend this board as QEMU gains more support for Versal hardware components. QEMU will generate a device-tree describing only the components it supports and includes in the virtual dev board. Before adding Versal support, this series starts with a few fixes to the GEM that I ran into when running recent kernels on the Versal and ZynqMP models. I also noticed a problem with HVC insns not being enabled when using QEMU's PSCI implementation on CPU's with EL2 and EL3 enabled. This causes problems for Linux/KVM guests, also fixed in this series. Best regards, Edgar ChangeLog: v3 -> v4: * Improve error handling for CPU and GIC creation * Remove KVM checks in GIC creation v2 -> v3: * Fix DESCONF6 queue mask generation for GEMs with only one queue. v1 -> v2: * Spell out OCM as On Chip Memory * apperture -> aperture * Remove copy+pasted virt board comment * Remove VMSD for Versal SoC (with a comment on why it's not needed) * Embedd AddressSpace dma object in GEM * Remove debug left-overs in arm-powerctl * Enable PMU in Cortex-A72 * Rename cortex_a57_a53_cp_reginfo -> cortex_a72_a57_a53_cp_reginfo Edgar E.
