but then when I do `tftp ker_cdtb_fs.scr` and `so` I have the wrong image format message
<Sout>
hmmm. looking at it (slightly sleep deprived so i might miss something) but i used the mkimage from https://www.denx.de/wiki/DULG/UBootScripts aka mkimage -T script -C none -n 'Demo Script File' -d setenv-commands setenv.img but it does look good
<wyre>
Sout, why .img instead .scr?
<Sout>
ahah just what the example used. (i have no idea i doubt it should matter)

Tartarus: the vac disabled me for two days and its still not great
<Tartarus>
marex: ouch
<marex>
the bonus headache was nasty
<marex>
seems better now tho
<Tartarus>
Looking at all of the lmb history is likely to re-issue that headache :(
<marex>
Tartarus: I would appreciate more cooperative approach from Jan there
<marex>
besides that, the LMB is a bit of a mess, yes
<Tartarus>
marex: Yeah, I think you need to (re?)read the last two emails I sent, once you're up to it.
<Tartarus>
marex: And looking at your commit message again, is part of the problem that reserved nodes cannot overlap?
<Tartarus>
And also if something like ce39ee28ec31b04c5c4e50d57a852ef8c1b2b26f might not be relevant to your use case?
<marex>
Tartarus: possibly, why ? (I need to refresh my memory on that)
<Tartarus>
(And that's not the commit I was looking for)
<Tartarus>
marex: I did some history digging yesterday and I think the revert is right. But I really don't want to make you feel shittier discussing it now, and can wait until you're up for it. I won't apply the revert right away.
<marex>
well, lemme catch up on the thread in a bit
<marex>
I think the LMB isnt well understood in general
<Tartarus>
Yes, agreed. And I think there may also be a need to think about / differentiate "protect U-Boot while it's running" from "mark an area as reserved in the device tree we pass down to the OS"
<Tartarus>
(With a quick side-long glance to PSCI stuff)
<marex>
Tartarus: we are mixing those two things together, are we not ?
<marex>
but as far as I can tell, the former is not a job for the LMB, the later is
<Tartarus>
marex: That's backwards. The first relevant commit here is to covert running U-Boot, and is from before U-Boot did anything to reserved-memory nodes
<Tartarus>
s/covert/cover/
<marex>
Tartarus: and why would we want to protect running u-boot ? just to prevent relocation from overwriting it ?
<marex>
that looks a bit odd to use LMB for that
<Tartarus>
(a) to cover a whole bunch of CVEs and then (b) yes, so we don't crash by overwriting ourselves in the normal non-malicious case of relocating things
<Tartarus>
It looks like e2237a2c263783996a85b70ccbf1f967aa2ec182 (2019) is when U-Boot first started to generally fiddle with reserved-memory nodes

<Tartarus>
But I also haven't found the commit I'm looking for...
<Tartarus>
Because it doesn't exist? I really want to know what the problem you're running in to here is
<Tartarus>
Or why covering running U-Boot with an LMB is a problem
<Tartarus>
As I don't see, but maybe just missed, where that becomes "and we reserve this memory space from the OS"
