Thanks for the into, jumping out now but I'll study it when I get home

smaeul: I tried to RE D1 BROM yesterday (to dig out how Allwinner BROM handles SPI NAND)
<MoeIcenowy>
and found that the same BROM now handles both eGON.BT0 and TOC0.GLH

machinehum: yeah, those priority values are only in the boot0 binary, not libdram. But there are more easily dumped from the regs after boot0 init'ed the DRAM
<apritzel>
I can do this later tonight when I am back at the board
<apritzel>
I am a bit doubtful that this will fix things, though, as I'd think that those values are just for fine tuning, and are not critical to the core operation?
<apritzel>
machinehum: anyway, many thanks for your work on this, getting the SPL and DRAM init to work would simplify so much for upstreaming
<apritzel>
machinehum: as mentioned, I got U-Boot proper to work, with MMC, and have some lead over why Ethernet doesn't work

aperezdc_: I also doubt those values are the exact thing we need, but if they're simple to dump out that would be amazing
<machinehum>
I can even do it, if you let me know how
<tuxd3v>
any sbc with BT5.0/5.1 support around??

machinehum: do you see accesses to 0x4002010 .. 0x400208c in the V5 libdram/boot0? probably a loop just writing stored values into every register in that range?
<apritzel>
translating back the values I read doesn't make too much sense, so I am wondering if I am looking at the right range ...

I can't find anything
<machinehum>
I did a search in Ghidra, nothing
<apritzel>
I see the "399" at mctl_com->tmr, as in the beginning of mctl_set_master_priority_a64()
<apritzel>
but the rest doesn't really add up, unless I am holding it wrong
rajkosto has quit [Ping timeout: 480 seconds]
<apritzel>
... and I do, because that's using the H6 sunxi_mctl_com_reg layout, of course
<apritzel>
reading the values this way gives reasonable values, now just need to decode
juri_ has joined #linux-sunxi
<apritzel>
but that also means that at least mctl_com is the H6 type, not the A64 (sunxi_dw) version
