Hi,

Add boot over DFU RAM as an alternate to running script at a fixed address like done today.

The main culprit is that it's not possible to do that on G12A/SM1 platforms due to changes in the USB boot protocol.

With this, U-Boot will present a DFU device with a ram slot where the Host could write a fitImage or legacy U-Boot image, then with the detach command boot will continue trying to boot the uploaded image.

Nice to see this! Next step would be to have this in U-Boot SPLin Amlogic SoCs in the future. I'm tempted to implement this in my tree before sending SPL support for (some) Amlogic SoCs upstream.

Cheers.
