Right now this is align with what devices are wired in qemu. Some Kconfig are enabled for SD and QSPI, etc. We will all these devices in future for sure. But as you know we are only enabling distro default not any internal commands which should be good sign for you. Thanks, Michal

Ah, ok, I figured since I saw changes to those components that they're also wired up already. It was hard to tell without the DT :). > But as you know we are only enabling distro default not any internal > commands which should be good sign for you. Yes, this is awesome! :) Alex

It was hard to tell without the DT :). It is really a question if we should continue with this enabling in this way or simply enable it for all arch because they are based on DT anyway. I am still lacking time to test all PS hard IP with microblaze which will also require some Kconfig to be updated. If you look at virt platform that this is using OF_BOARD and DT passed by qemu which should ensure that qemu is the key element in generating these DTs for u-boot and Linux. Thanks, Michal

I agree that we probably want something smarter in the long run, maybe even w/o OF_BOARD because you could have most of the targets available via PCIe for example. Alex

I am thinking about board self identification and image with more dtbs but I am not quite sure how this should work with pcie based cards. Thanks, Michal

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. The patch is adding necessary infrastructure in place without enabling platform which is done in separate patch.
