Hi - hoping I can somehow ping @Immibis.
Try sending a private message. This version of phpBB is way too old for any of that Web 2.0 @ notification business.

While reading through your DRAM initialization code I noticed that all registers are in the 0x01c2 and 0x01c6 blocks, but one register is written at 0x016C3104? This looks like a typo, maybe this helps stability? Or is this intentional?
I don't see U-Boot poking anything near that address, and I do see U-Boot poking the register at 0x01C63104 with a similar value, so I'd say that's a typo. Unfortunately, it doesn't look like Allwinner ever published complete documentation for the A64 DRAM controller, so you'd have to dig up a datasheet for a similar SOC to figure out what any of those values actually mean. (According to U-Boot, that includes the H3, H5, R40, V3s, and probably a few others.) You could also try reverse-engineering Allwinner's DRAM initialization code, since that seems to be what the U-Boot authors did.
