Hello, It's sensible work by Allwinner to release the dram code under GPLv2.
Now, we can have mainline u-boot support for A33 soon.
Hans, Yes, I've very basic A33 dts created based on A23, still lot to do.
About the dts, so far the memory maps look the same. I haven't checked the clocks or interrupts, but I bet they are the same as well.
Could we use an overlay over A23 with just the different pieces overriden? Though they're not the same piece of silicon, they are damn close. Maybe even the PIO is the same.
I'd prefer something like sun8i.dtsi, and then include it from both sun8i-a23.dtsi and sun8i-a33.dtsi, like we did recently for sun5i, but that's a detail.
But yeah, if they're that close, we should definitely share as much as possible.
