Hi Michal,

I was checking spl/u-boot-spl.dtb and I see that you are removing interrupt-parent property but I think that also make sense to remove interrupt property as well because it is unused and parent is also removed. Just extend OF_SPL_REMOVE_PROPS by "interrupts" to save some memory.
I'm fine with this.
Another thing I was checking was that we are missing rules for removing nodes with status = "disabled" property. I think that will be good to add it. The reason is that I would move all that u-boot,dm-pre-reloc to dtsi at least for now.
Hmmm. I prefer to add this "u-boot,dm-pre-reloc" to the board dts file instead of using the dtsi files. At least for the real devices, like UART etc. As they vary between the different boards.
How do you handle if you have 2 uarts which one is primary one? That only one has dm-pre-reloc? Or are you using aliases?
Perhaps its possible to enable those busses (simple-bus) needed to traverse to the requested device automatically via fdtgrep? That would make this much easier and less error-prone. And would result in less "u-boot,dm-pre-reloc" occurances in the dts / dtsi files.
I still think that instead of putting this property to every node having one property with list of devices in chosen node is better way. But I haven't had a time to play with it.
Thanks, Michal
