Where do you check that the device tree fits in OCRAM? What about when SPL is occupying OCRAM? Does the device tree get used with SPL (I don't think we were using FDT control at all the last time I worked with SPL on these chips)?
I checked ls2085ardb dtb size in Linux. It is ~30K. So from 0xfff0 to 20000 there is enough space.
For SPL. Assumption is SPL never use dts. It will only be used by u-boot. Once control is transferred to u-boot, things work as it is like NOR boot.
I don't think that's a good assumption, given that I just saw a patch posted regarding SPL_OF_CONTROL.
