Do you think we might be able to retire the Rockchip loader one day?
If the feature and performance is almost the same, then Rockchip loader is no need any more, and that's what I'm try to do. - rockcusb & fastboot gadget performance, as I have comment in Eddie's patch long time ago, the dfu in U-Boot is using single buffer, which is very slow compare to mass storage gadget. - Android boot, it's still not have full support for Android image like recovery in U-Boot now. - Secure boot, I have not verify this part on upstream U-Boot, but rockchip needs it. - some other feature used by our product
Thanks, - Kever
