project:cfg:BoardConfig_IPC: Added fastboot BoardConfig file and firmware post-scripts, distinguishing between the BoardConfigs for Luckfox Pico Pro and Luckfox Pico Max. project:app: Added fastboot_client and rk_smart_door for quick boot applications; updated rkipc app to adapt to the latest media library. media:samples: Added more usage examples. media:rockit: Fixed bugs; removed support for retrieving data frames from VPSS. media:isp: Updated rkaiq library and related tools to support connection to RKISP_Tuner. sysdrv:Makefile: Added support for compiling drv_ko on Luckfox Pico Ultra W using Ubuntu; added support for custom root filesystem. sysdrv:tools:board: Updated Buildroot optional mirror sources, updated some software versions, and stored device tree files and configuration files that undergo multiple modifications for U-Boot and kernel separately. sysdrv:source:mcu: Used RISC-V MCU SDK with RT-Thread system, mainly for initializing camera AE during quick boot. sysdrv:source:uboot: Added support for fastboot; added high baud rate DDR bin for serial firmware upgrades. sysdrv:source:kernel: Upgraded to version 5.10.160; increased NPU frequency for RV1106G3; added support for fastboot.
