<jernej> apritzel, smaeul: It looks like TF-A v2.7 doesn't work at all on H6 boards without PMIC, like Tanix TX6 or TX6 mini
<jernej> it errors out around probing time
<MoeIcenowy> apritzel: TBH the current env decision is a total mess

<gamiee> Hello, does sunxi chips have something like efuses, but without it bits being burned forever?

<jakllsch> gamiee: what would be the point?
<gamiee> jakllsch: storing things like slot which boot from (A/B), last successful boot etc. But probably will use u-boot env for that.
<jakllsch> yeah, that's a NVRAM sort of thing, not a fuse sort of thing
<gamiee> Ohh, NVRAM is the word I was looking for :) Thanks
<gamiee> Although, I guess Sunxi SoCs don't have any NVRAMs inside, or ?
<gamiee> Atleast, I can't find info about it.
<jakllsch> sometimes it's in the PMIC
<gamiee> My board doesn't have PMIC (long-live 2 CPU voltages /s)
<gamiee> So I guess only way is u-boot env on eMMC
<buZz> some sbcs have a spi eeprom place on pcb, not always populated
chuangzh1 has joined #linux-sunxi
<jakllsch> or a RTC chip that also has nvram
<buZz> yeah

<jernej> I have only one board with such issues and it seems that it works without any workaround on Linux 6.0.
<jernej> Can anyone confirm that?
<gamiee> jernej: HI! I had issues on PINE H64, eMMC was working just fine, and after something, it didn't booted anymore. U-boot worked, but something during kernel boot failed.
<jernej> gamiee: did you use above patch to workaround the issue?

<hexdump0815> jernej: i had some h6 tv box where this patch was required to make emmc work back then
<gamiee> jernej: I wasn't aware of this workaround, but I might try it
<jernej> gamiee: my question is actually opposite - if it's not needed anymore with 6.0. but if you test it, please test it both ways on 6.0 and let me know
<jernej> hexdump0815: is still needed with 6.0?

<hexdump0815> jernej: i have no v6.0 kernel yet for the h6 - will test it when i get to it, but might take a bit ... will put it onto my todo list to not forget

<apritzel> gamiee: since you need to load the SPL from some kind of external storage anyway, that's somewhat naturally also the place to store those settings
<apritzel> as you said: U-Boot environment
evgeny_boger has quit [Remote host closed the connection]
<apritzel> also eMMCs typically provide some persistent bits, outside of the actual storage
<apritzel> if you are after a/b boot: eMMCs allow to choose between boot partition 1 and 2, and this setting is persistent
<apritzel> jernej: so do you think (hope?) that something in 6.0-rc1 fixed the issue, and are thinking about bisecting that?
apritzel has quit [Ping timeout: 480 seconds]
<karlp> gamiee: you can find a few little bits tucked away in emmc config words... you can also use the rpsmb stuff on the emmc maybe?
<karlp> also, youv'e got two special private boot partitions you can stash stuff in...
