hey calebccff, im following ur slides to get msm8960 up and im a bit confused on step 2 of dt match data. it says to copy the compatible strings and match data from Linux, but all the compatibles that ive identified from my dts(i) dont have a corresponding file in uboot: https://pastebin.com/dbb3stFc . im wondering if at this point u tried to compile uboot and used ur best guess or instead brought
<LogicalErzor>
these drivers in from Linux? thanks in advance

<Tartarus>
linfax: What platform is this for?
<apalos>
Tartarus: the .lds changes are all over the place. I either send a huge unreadable patch
<apalos>
Or i break them up nicely, but u-boot won't compile for some boards in between those commits
<apalos>
alternatively I can make it compile with 'unpredictable' results, but I really dont like that
<apalos>
any preference on the poison ?
<Tartarus>
Find as much to break out as you can before having to make just one big go of it all, please
<apalos>
I did, not exactly doable
<apalos>
the problem is that some variables are defined as linker symbols, while other are c variables
<apalos>
and are used by both v7/v8 and some 'special' board linker scripts, spl tpl, etc
macromorgan_ is now known as macromorgan

I'll see if i can make it more readable

<Tartarus>
OK
<Tartarus>
If you can't, you can't, but please give it one more go.
<calebccff>
LogicalErzor: you need a clock driver of some kind, I'd suggest copying the clock-apq8016 driver, fixing the dt-binding include and then just emptying all the functions out. If you're chainloading from aboot then the UART clock will be up already so you can enable the serial_msm debug UART and at that point you should at least get some prints
<calebccff>
the stub clock/pinctrl drivers initially are just there so U-Boot doesn't crash out, as pretty much everything has some kind of clock... We can just rely on the clocks being a relatively useful state to begin with
prabhakarlad has joined #u-boot
<apalos>
Tartarus: ok, a reasonable alternative is to rip out the sections one by one
<Tartarus>
OK
<apalos>
Will end up with more readable patches, but the series will be big, but that's better
<Tartarus>
And if you can run the qemus each commit, that'd be good
<Tartarus>
I know that'll take a while
<apalos>
I run the CI on each commit + add prints to make sure the calculated size doesnt change
<Tartarus>
But I do worry about some unexpected fallouts, so bisectable run testing to some degree is good
<Tartarus>
great, thanks
<apalos>
yea smaller changes will be completely bisectable,
<apalos>
i'll do that
<apalos>
also (obviously) i prefer this going into -next :>

Hello
<quinq>
I hope I'm in the right channel, I'd need help for using a serial line on my board
<quinq>
I can see several devices with 'dm tree', like serial@21c0000, serial@21d0000, etc.
<quinq>
But I don't know how to set stdout to those
<quinq>
I tried 'setenv stdout serial@21d0000' but I get an error '## Error inserting "stdout" variable, errno=22'
<quinq>
Am I doing it wrong?
<quinq>
Also coninfo lists (only) to devices, "serial_plx01x" and "serial", but not the others (I have three UARTS configured as "okay" in the device tree)
<mps>
quinq: in my case it is 'stdout=serial,vidconsole'
<mps>
and serial is 'serial#=165166c80ac2c8b7'
<mps>
on one of boards where I can look right now
<quinq>
I have no serial defined, and stdout is by default "serial_plx01x", but that's the name of the driver, not of a device
<Tartarus>
Well, serial# isn't about the serial port
<Tartarus>
That's the serial number of the board in question
<quinq>
:D
<mps>
Tartarus: yes, missed '#'
<Tartarus>
OK :)
<Tartarus>
quinq: Do you have SYS_CONSOLE_ENV_OVERWRITE enabled?
<mps>
obviosly it is number
<quinq>
Tartarus, checking
<quinq>
No it's not
<Tartarus>
Well, that's the first thing to fix then
<mps>
interesting, in qemu-u-boot for riscv64 it is 'stdout=serial@10000000'
<quinq>

I get the same error
<quinq>
My bad, building script erased the .config.

in board code an empty function board_early_init_f() only returning 0 can be dropped entirely, right?

Hi there, I have a MIPS system with U-Boot and I would like to verify if my understanding is that U-Boot does not append to existing DTB bootargs but overwrite them and if there's no easy way to make the kernel or U-Boot understand this behavior?
persmule has quit [Ping timeout: 255 seconds]
<Tartarus>
Yes, we set the bootargs we don't append the bootargs
