I don’t have specific information about implementing a framebuffer-based splash screen for Verdin iMX8MP in the available sources. The documentation I have access to covers U-Boot splash screens (1) and general splash screen approaches (2), but doesn’t provide detailed Yocto recipes for kernel-level framebuffer splash implementation on your specific platform.
Check out these potentially useful sources: Splash Screen on U-Boot, Splash Screen on Toradex Computer on Modules, Inquiry about Adding a Boot Logo on Yocto for iMX8MP Verdin
Would you like me to provide a general answer based on my knowledge instead?
