2025.2 Changes

Migrated all designs and PetaLinux projects to Vivado / Vitis / PetaLinux 2025.2
Moved to the SDT (System Device Tree) flow for PetaLinux configuration
HailoRT and hailo_pci updated to 4.23.0; backported the find_vma() / mmap_read_lock fix as a kernel ≥ 6.5 hotfix for the v4.23 driver
Added three Xilinx DRM kernel patches required when v_mix runs in DRM-bridge mode (mixer NULL-deref, double-cleanup on unbind, vblank shutdown ordering); kernel cmdline now passes xlnx_mixer.connect_drm_bridge=1
meta-hailo is now consumed as a git submodule tracking the hailo8-scarthgap branch and copied into each project at configure time; packagegroup-hailo-tappas no longer pulls in the removed tappas-apps legacy recipe
LICENSE_PATH is rewritten from = to += in the project-local copy of meta-hailo-tappas/conf/layer.conf so meta-qt5’s licenses survive (qtbase otherwise fails do_create_spdx)
Added a check_ca_workaround Make target that fails fast with the one-time sudo symlink fix for the PetaLinux 2025.2 eSDK git-native CA-bundle relocation issue
ZCU104 BSP adds an explicit sdhci1 device-tree override (Opsero ZynqMP designs export a minimal sdhci1 node; without the override SD init fails with -110)
UltraZed-EV BSP forces PMUFW/FSBL/TF-A/Linux serial to PSU_UART_0 (gen-machine-conf defaults to UART_1 on this carrier in 2025.2)

Removed VVAS multiscaler accelerator from all designs (Xilinx has no support for 2024.1)
Added AXI4-Streaming Data FIFO to MIPI video pipes, between MIPI CSI2 RX and ISP Pipeline IPs
Improved documentation, centralized target design info to JSON file
RPi camera IOs are properly driven
ISP Pipeline IP updated to version v2023.2_update1 of the Vitis_Libraries repo
ISP Pipeline now uses built-in Linux driver (linux-xlnx/drivers/media/platform/xilinx/xilinx-isppipeline.c)
Removed all Vitis-AI and VVAS recipes from BSPs
Improved example scripts: use max res of connected display, display only connected cameras
