07:26 <PabloPL> Are there any plans to support exynos ufs in mainline (or maybe someone is already working on this)? I found only some 5 years old patchset https://lore.kernel.org/patchwork/cover/616149/

07:28 <PabloPL> It did applied with some minor changes to mainline (also some patches are already merged)

07:54 <krzk> PabloPL: I am not aware of. The work I saw in August was about HW encryption of storage (including UFS)

07:54 <krzk> [PATCH 0/9] Flash Memory Protector Support

07:54 <krzk> from boojin.kim <boojin.kim@samsung.com>

07:55 <krzk> PabloPL: Samsung LSI (the vendor behind Exynos) frequently looses interest in upstreaming patches so I would not expect much work there... Maybe new Android with mainline-requirement will change something... or not... Anyway feel free to continue that work :)

07:57 <PabloPL> krzk: Ok, i need ufs since s6 don't have mmc/sdcard :/ (but why both mmc slots are enabled on vendor kernel - no idea). Wifi is on pci

08:03 <PabloPL> krzk: LSI could fix some issues with sboot at first - for example those workaround for timers (which was fixed by patches from mszyprow, but they won't get accepted in mainline)

08:05 <krzk> PabloPL: LSI does not care :)

08:05 <krzk> PabloPL: Do not expect anything coming from them...

08:08 <PabloPL> krzk: i wonder if they would do review of any patches

08:09 <PabloPL> krzk: or not care at all

08:16 <PabloPL> krzk: like any many other vendors probably - instead of working on adding/improving code in mainline, they can just release next devices/etc and earn money

08:17 <PabloPL> mszyprow: Hi. Just curious (since i got it working with all Your patches) Any alternatives to https://patchwork.kernel.org/patch/10630653/ ? That was also needed to fix timers

10:44 <mszyprow> PabloPL: sadly, nope

10:45 <mszyprow> PabloPL: the only alternative would be to use arm32 kernel

10:54 <PabloPL> mszyprow: Can this be somehow fixed with custom uboot? I woud like to get rid of this and also that custom boot.img format (with custom dtb.img)

10:55 <mszyprow> PabloPL: this needs a fix in hypervisor/secure world

10:55 <mszyprow> PabloPL: you would need to replace signed sboot with something else

10:55 <PabloPL> mszyprow: probably not "easy" as on s5pv210 :(

10:55 <mszyprow> PabloPL: assuming you will manage somehow to sign your replacement binary...

10:56 <mszyprow> PabloPL: nope, s5pv210 didn't have secure world mode

10:58 <PabloPL> mszyprow: i was thinking about that signature from odroid which could be attached to uboot to make it boot as replacement of all bootloaders on s5pv210

10:59 <mszyprow> PabloPL: there are easily available dev boards with 7420....

10:59 <PabloPL> mszyprow: on galaxy s1 there was also some signature check and in this way it was bypassed

11:00 <PabloPL> mszyprow: other than MV7420?

11:00 <mszyprow> PabloPL: well, not really bypassed, you simply replaced it with open bootloader from Odroid board

11:02 <mszyprow> well, if you can really get it...

11:03 <mszyprow> bl1 from mv7420 should theoretically work on s6

11:07 <PabloPL> mszyprow: hm..the same way as we do on s1 where we also use signed BL1_stage1. will think about this later

11:07 <PabloPL> mszyprow: many things missing for 7420 - display/ufs at first

11:08 <PabloPL> mszyprow: why it was named exynos7, not exynos7420 like uboot (i already asked about this some time ago here)

11:09 <PabloPL> and got information that espresso7420 is not 7420 but something close to it (called exynos7)...

11:09 <mszyprow> PabloPL: I really have no idea

11:09 <PabloPL> i hope that i won't have to rename all exynos7 to exynos7420 compatibles/dts/dtsi/etc if pushing s6 into mainline

11:20 <mszyprow> PabloPL: frankly I would drop this 'exynos7' oddness

11:25 <PabloPL> mszyprow: just the board dts or all support for this (tmu/mmc/i2c/etc compatibles)?

11:26 <PabloPL> mszyprow: probably create 7420 from scratch (maybe reusing something what can be)

11:26 <mszyprow> PabloPL: we can discuss this once you have it working :)

11:27 <mszyprow> PabloPL: and some v1 rtc patches ready

11:27 <PabloPL> mszyprow: working in some (any) future ;) ?

11:28 <PabloPL> mszyprow: ok, for now i have it boot till missing root (no sdcard in hw, so need to look at ufs)

11:28 <mszyprow> PabloPL: nope, something you want to send to mainline, so one with s6 can flash and check
