- Introduced device tree patches for MF68E and M9S, adding their respective .dts files and updating the Makefile to include them. - Implemented framebuffer driver for the GC9107 LCD controller, enabling display support for the MF68E and M9S devices. - Created UCI defaults for modem management, including network interface configurations and LED handling for modem and WiFi indicators. - Added scripts for automatic formatting of the rootfs_data partition and generating GPT images for MSM8916 eMMC. - Included hotplug scripts for managing LED states based on device actions. - Updated README with instructions for re-integrating the deprecated device support into the main build.
