luckfox-eng29 8f34c2760d project:build.sh: Added fastboot support; custom modifications to U-Boot and kernel implemented using patches.
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.
