anarsoul: I couldn't find any obvious reason why SPL won't even try to boot from eMMC, so I've just gone back to the "works for me" setup I had before
<anarsoul>
I see
<robmur01>
I've already got a long enough list of kernel stuff I'd like to hack on, without trying to learn u-boot on top of that ;)
<anarsoul>
robmur01: guess I'll wait for rk3399 gurus then
<robmur01>
you and me both!
<anarsoul>
mmind00: any chance that you can look into reboot issue on rk3399?
* mmind00
also isn't a Guru
<mmind00>
and sadly the list of things I _need_ to tackle is somewhat long
<anarsoul>
IIRC Kever said that mainline u-boot is not primary target for Rockchip
<anarsoul>
so looks like we have no one to look into it :(

mmind00: there's a patch in BSP kernel that doubles bandwidth of USB3 ports on rk3399: https://pastebin.com/KnKpRGGR
<anarsoul>
do we want the same upstream?
field^Zzz3 has quit [Ping timeout: 246 seconds]
<mmind00>
anarsoul: maybe :-) ... doesn't look overly dangerous ... maybe you could do a performance comparison for an actual commit message :-)
<anarsoul>
mmind00: that's from pinebook pro chat. I've got only 1 USB3 HDD that can't even saturate USB3 bandwidth so unfortunately I can't do any benchmarks
<mmind00>
anarsoul: do they have performance comparisons?
<anarsoul>
not yet

mmind00: are you aware of any rk3399 errata that may result in soft reset not resetting SoC completely?
vagrantc has joined #linux-rockchip
<mmind00>
anarsoul: nope ... I also generally do not have more knowledge than anybody else ... I only get TRMs slightly earlier (before some random chinese company leaks them)
<anarsoul>
I see
<anarsoul>
any contacts within Rockchip who could shed some light?
<anarsoul>
mmind00: RK3399 TRM says: "2.9.4 Global software reset": "Glb_srstn_1 resets almost all logic."
<anarsoul>
why it's "almost"?
<mmind00>
anarsoul: there are two reset modes, one softer and one "harder" in some form
<anarsoul>
yeah, "harder" resets "almost all logic"
<anarsoul>
so I guess the question is what is not reset?
<anarsoul>
also
<anarsoul>
u-boot/arch/arm/mach-rockchip/rk3399/rk3399.c:spl_board_init() mentions that there can be issues with soft reset and they've been worked around in linux, ATF and u-boot
<anarsoul>
I don't see anything special in u-boot, ATF nor linux. They just write magic value to the register
<anarsoul>
I wonder if we're missing a workaround :\
