Hi,
I've posted a couple of improvements to the in-tree ddr training code but we've known for a while that u-boot proper is a bit behind Marvell's code for ddr training. And now I really do have a problem on my board that is fixed by using Marvell's code.
Yesterday I got hold of patches from Marvell for their "standalone" mv_ddr code. It's under a tri-license Proprietary/GPL/BSD-3c so I've exercised my rights under the GPL and made it available on github https://github.com/cpackham/mv_ddr.git
Actually looks like Marvell have their own official one https://github.com/MarvellEmbeddedProcessors/mv-ddr-marvell.git so there's no need for mine. I'll take it down to avoid confusion.
This standalone code looks the most u-boot-ish of any code I've gotten out of Marvell. In fact I suspect it was based on the work that Stefan did initially.
The question how do I get this upstream I could submit 475 odd patches preserving the authorship, I could submit one big roll-up of changes. Neither option is particularly appealing. It would be hard to narrow down the subset of changes that fixes my particular problem.
Any suggestions on how to proceed?
