It's 4 days before, "U-Boot] sunxi: regression in dram init for h3 board"
7 days is not 4-days :)
True, it was last week, not a week ago.
I would expect some debugging on this during these days and find the real root cause.
Just so there's no unmet expectations here, I'm not doing any _debugging_ of this. (Nor do I have any planned) Given that this is a regression in working devices, I would _presume_ (quite likely wrongly) that the honus of debugging this would be on the people who suggested this patch, not people affected by it. I'm happy to test things, but I have zero experience with dram init, (only marginally greater than zero experience with uboot overall) and no sane methods for debugging this further, nor enough devices to give any test confidence that any debugging I could do would be useful.
Do you have error after relocation or before relocation? Does it go outside and print DRAM size?
When I tested, I replaced hang there with reboot and got following outputs after multiple FEL uboot uploads commands:
