Could you send these two boards in a separate series so that we avoid merging them for now (because SPL support is broken) and then re- iterate the series later with the DDR bringup? Or maybe find a way to disable SPL support, but in any case, it's not ok to merge a board with SPL enabled and broken.

I have explained the details about this concern on v2 [1], thought you would comeback on the same line instead here. Anyway, making SPL as an optional is not an idea to go with Mainline as we make many decisions with regards to make SPL is mandatory. Since the DDR is show stopper here (and it would really need a good amount of time, since it effect the other boards), I can go with TPL enabled boot-chain where ddr bin, SPL and U-Boot proper can be part of booting stages. This way we can avoid skipping SPL usage, and many config changes to make SPL optional. [1] https://patchwork.ozlabs.org/cover/1086213/

Yes, you have already explained the issue, but I don't think it's enough a justification to merge broken SPL support. If it was only partial or limited, it would be fine, but here it's just broken. > Anyway, making SPL as an optional is not an idea to go with Mainline > as we make many decisions with regards to make SPL is mandatory. Yes I think making SPL mandatory is a good idea, so that's why I'm suggesting that we don't merge the boards until they have SPL support. > Since the DDR is show stopper here (and it would really need a good > amount of time, since it effect the other boards), I can go with TPL > enabled boot-chain where ddr bin, SPL and U-Boot proper can be part of > booting stages.

People who really want to use them with the rockchip blob can cherry-pick the patches from the list in the meantime. It also creates incentive for people to free the DDR init, since that becomes a condition to have the board upstream. What do you think? Cheers, Paul

I don't know whether you get my point or not? these boards are not merged yet. What I'm saying is we are going to support them with TPL-enabled, that was SPL can make use of these boards which still a valid boot-chain. moreover this way can avoid touching core files and no specific change require while supporting ddr dtsi.

Ah maybe I missed the point indeed. So what you are suggesting is: rkboot (acts as TPL) -> SPL -> U-Boot? Then I have no problem what that. Cheers, Paul

Well, my initial point was to forbid merging broken SPL support, but I am totally in favor of requiring free DRAM init for merging new boards. Sadly it's hard to enforce this as a general rule in U-Boot since some platforms are plagued by non-free first-stage bootloaders because of signature checks, and that's where DRAM init happens. But for RK3399, we can totally have that rule, which directly creates incentive to free the blobs. Cheers, Paul

True, I agree this point. Since we have an option of having DRAM init at TPL I'm proposing this boot-chain (along with commitment on dram work).
