Does these two tool have the same functionality? I don't know the second 
one :(

And I know there is another tool named rkdeveloptool from rockchip.

What's the main target for this patchset, boot from usb with ramboot 
support and without any eMMC/SD/SPI driver?

I would prefer to keep using one tool instead of two or more tools, so I 
don't think

enable DFU in SPL is a good idea, using rockusb in SPL is better here.


Thanks,
