Hi Kever and Vagrant,
I tested this patch on my rock2 board against 2016.09. (I didn't have my board with me over the weekend)
Thanks for your test and for your log, my source code do have one bug and I have fix and upload the V2 patch set.
- It seems the BACK_TO_BROM feature is broken. It doesn't boot using
the 2016.09. I'm afraid I don't have the time to track it down.
It works fine on my evb, do you flash the image correctly? it's different with the way you don't use BACK_TO_BROM.

- It seems the SPL is still small enough to test this feature.
(vagrant you can forget about the back to brom feature unless you need more SPL space).
- I get the same behavior as Vagrant on the rock2 board. I'm
including DEBUG output in case that helps Kever. I tried to trace it, but it seems a larger undertaking than I can manage right now. (vagrant, you can add DEBUG #define's into the file include/configs/firefly-rk3288.h to get the output below.. my guess is it's similar.)
This trace is almost exactly the same between enabling the SDRAM detection and not. I marked the point where it halts. The fdt is a slightly different size, but that is expected.
