Hi Simon, I've read the code for spl handoff. It's a good way though but unfortunately it cannot be applied to the MT7623 boards. The reason is that MT7623 uses a MediaTek proprietary preloader which has the same function as the U-Boot SPL. But the preloader is close-sourced (by company policy) and only available in binary release. This means we can't use a real U-Boot SPL to replace the preloader. At present this chip has already been used in many products. We can't either release a different preloader which introduces compatibility issues. So the conclusion is that we cannot use the bloblist feature for this SoC.
