Here's a series that has a lot going on, but I didn't want to split it to allow everyone to understand the motivation between some of the changes to the SPL/TPL framework. The short summary of this is "enablement for DRAM init on the RK3368 with everything else that's necessary to do it using OF_PLATDATA in TPL".
Enabling the RK3368 created a few more challenges that I'd expected:
I needed different stack locations, text addresses and sizes for
TPL and SPL
the TPL stage was to use OF_PLATDATA and SPL was to use full
OF_CONTROL
- with the RK3368 TPL stage, there was a need to extend the
back-to-bootrom
support for Rockchip to AArch64
I wanted to start folding some of the Rockchip specific SPL support
(i.e. back-to-bootrom) back into the general SPL framework to allow using it as a general boot method
I have a confusion here: according to the README.TPL, TPL is Third Program Loader, which loaded by the SPL. So I think it should run after the SPL. But from RK3188 and RK3368 TPL implementation , they all run before SPL.Maybe it is my misunderstanding, hope to get some guidance.:-)>
I think you are right and most Rockchip boards have been using this the wrong way around.
Actually at first I also had the ordering of SPL -> TPL -> uboot for rk3188 but after discussions with Simon and Tom Rini, the opinion was that TPL stands for "tiny" program loader and should run before the full SPL.
So I switched that stuff around on rk3188.

Only RK3188 uses TPL now.With the fine-grained configurability that I created for the RK3368, it will be easy enough to switch this around on the RK3368. However, this will then also be done for the other RK3xxx devices to restore consistency.
I would prefer to first add the RK3368 support with the “backwards TPL/SPL” (i.e. TPL before SPL) to remain consistent with current mach-rockchip usage of the TPL/SPL terminology. Once this is merged, we can then switch this around for each board individually.>
So I ended up separating quite a bit of features between SPL and TPL while keeping things transparent to the few other boards using TPL (at least I hope that things are transparent, as we didn't have any of those in our lab to test on)...
Tested with: RK3368-uQ7, Debian 9, Linux 4.13-rc1.
Just one final remark: the DMC driver for the RK3368 currently covers the configuration we use on the RK3368-uQ7 (i.e. 32bit wide, 2 ranks) and is stress-tested (including 8-way SPEC runs) at all 3 supported speeds. I've built a bit of infrastructure (e.g. the way the memory-schedule is determined) that I hope will be a useful starting-point in unifying the drivers for the various closely related DRAM controllers (e.g. for the RK3288) for Rockchip devices in the future.
