Hi,
This is a bit painful series, so apologies in advance for the patchbomb. I did'nt see any clean way to do this, so here goes.
First: there are dts mismatches and overrides being done in u-boot in varied manner that should have been submitted to kernel.org in the first place, so, https://lore.kernel.org/linux-devicetree/20230414073328.381336-1-nm@ti.com/
This series picks some of those nodes up and marks them so that merge is a lot more logical. There are still stuff like esm and cpsw that will need a little more work.
This series cleans up the dt, switches to .env mode and finally defaults to distroboot with none of the fancy stuff.
I have tried to maintain bisectability, but the r5-sk stuff is a bit too broken for me to succeed cleanly.. but it did'nt make sense to confuse review by squashing everything up. Let me know if there is a better bisect option, and I can try.
Logs are available: (including a log with the last two patches applied for distoboot default) https://gist.github.com/nmenon/6b09f55251225d3f3cce076c32a33bba Tested along with the ethernet fixup I had sent earlier: https://lore.kernel.org/u-boot/20230414042433.3436425-1-nm@ti.com/
