<alexey> @narmstrong Hello! Sorry for the noise, but more than a week ago, I sent my patch with the implementation of meson secure pwrc driver to U-Boot, but I haven't received any feedback :( When it's time, please review. Thank you!
<narmstrong> alexey: i don’t have it, seems you forgot to cc the amlogic uboot ML

<f_> hi all! Sorry for the noise with f_|catgirl.

<f_> Last time I added support for booting SCP images, but turns out it doesn't work (just like loading BL31, meh)!
<f_> Pushed all I have to my git server. Let's continue!
<narmstrong> f_: maybe a header issue ? do you right the right payload ?
<f_> No idea \o/
<f_> In the case of BL31, it tries to load using memmap but as soon as it calls memcpy it resets.
<f_> No idea about SCP.
<f_> But it could be a header issue...
<narmstrong> rockosov: ok I missed the serie because Alexey used my old baylibre email
<f_> narmstrong: You don't work at BayLibre anymore do you?
<narmstrong> f_: nop since last sept
<f_> Sure.

<rockosov> narmstrong: Ah, sorry for that
<rockosov> narmstrong: About the pwrc node location. This is the same situation which I've found before on the kernel side
<rockosov> narmstrong: But main difference between kernel and uboot, that uboot doesn't have the appropriate sm driver which can call of_populate() API. That's why Alexey did such a hack
<f_> rockosov: Sorry for the off-topic question, but if I understand correctly, you're working at Sberdevices and Sberdevices produces set-top boxes?
<narmstrong> rockosov: you should be able to add a UCLASS_SIMPLE_BUS driver for that
<rockosov> f_: Yep, I'm from SberDevices. We are producing not only set-top boxes, but different multimedia devices with smart assistance (like Amazon Alexa, but in Russian)
<rockosov> f_: We have set-top boxes, smart displays, set-top box with smart camera (A311D based), two smart speakers (A113L and A113X based)
<f_> rockosov: Nice to see manufacturers contributing to mainline U-Boot and linux! =)
<rockosov> narmstrong: Yep, we thought about it... But assumed this is good things for separate patch series. But I get your point, I'll ask Alexey to prepare simple bus driver (today he is OOO)
<rockosov> f_: We're so happy to be working with the fantastic linux-amlogic community! It's such a pleasure to collaborate with such a cool group of people! :)
<f_> And it's a pleasure to work with people that care about their customers more than most other people (looking at you, videostrong)!
<f_> Anyways, my not-so-professional logs tell me that it's the exact same thing happening with SCP_BL2...
<f_> WARNING: oh hi im memmap
<f_> WARNING: oh hi
<f_> WARNING: im still holding strong
<f_> Nothing else after memcpy().
<f_> Fails here in load_image()
<f_> If we zooooooooom a bit closer...
<f_> This is the memcpy() call I'm talking about.
<f_> ((uintptr_t)(fp->base + fp->file_pos)) looks like a memory address, right?
<narmstrong> rockosov: thanks :-) and thanks again for your work, it’s valuable for all of us
<rockosov> narmstrong: :)
<f_> What could be causing this?...
<f_> do we have some Amlogic staff here? lol
<rockosov> f_: hahahaha
<f_> just so that I ask them how to do DDR init, pls
<f_> i'm a lovely cat i won't hurt you
<f_> please tell me how to init your dram
<f_> pleaaaaaase
<f_> lol
<f_> Is it just me or what is going on with codesnake/WeTek's (old??) U-Boot tree
<f_> We'd have to ask codesnake :D
<f_> I sure love code provenance issues!
<f_> Looks like it's for U-Boot SPL??....
<f_> Reversing BL2, with help from early BL2 code, could definitely help in that case.
