<paulk-collins> hi there
<Wizzup> heya.
<paulk-collins> I was told that the exynos 5800 peach-pi allows booting an unsigned first stage bootloader, is that correct?
<paulk-collins> as-in, using the U-Boot SPL directly instead of Samsung's BL1
<Wizzup> That I do not know. I would be interested if that was the case
<paulk-collins> so would I :)
<paulk-collins> anyone around here with peach-pi?
<sjoerd> paulk-collins: if you update the flash you probably can
<sjoerd> (boot the SPL)
<sjoerd> though i thought the bl1 stage would be the one turning of the signature requirement
<paulk-collins> sjoerd, it does boot off a SPI flash, doesn't it?
<sjoerd> it does indeed
<paulk-collins> sjoerd, well I'd really like to run the SPL at first, not chainloaded
<javier__> paulk-collins: I don't believe u-boot SPL can be booted directly since the BL1 does some pre boot init
<javier__> paulk-collins: remember that u-boot SPL is BL2
<sjoerd> while bl2 is the u-boot SPL
<javier__> sjoerd: nod
<sjoerd> javier__: you beat me to it :)
<javier__> sjoerd :)
<paulk-collins> right, but I'd want to find out whether it's possible (provided we add the missing bits of hw init to the U-Boot SPL) or whether BL1 is signed by samsung
<sjoerd> pretty sure bl1 is signed
<paulk-collins> an easy way to find out would be to change a string in BL1
<paulk-collins> right, I was too, but was recently told it's not the case on this particular device
<sjoerd> You could drop sjg1 a mail given he did the u-boot enablement for the peach
<paulk-collins> he probably knows indeed :)
<paulk-collins> anyways, I was hoping it would be kind of a known fact
<paulk-collins> perhaps the person I was talking too mixed things up and really meant that the U-Boot SPL could be chainloaded from BL1
<paulk-collins> talking to*
<javier__> paulk-collins: I don't know tbh, if I would have to guess, I would say that BL1 is signed by samsung and just a binary provided to Google that they used
<paulk-collins> if BL1 is indeed used on the device, that sounds likely
<paulk-collins> also, I had never heard of exynos platforms not enforcing signature checks before
<javier__> paulk-collins: now, the verified boot is implemented in u-boot afaik
<javier__> and that can be replaced by disabling the SPI flash wp
<paulk-collins> javier__, you mean cros vboot?
<javier__> yeah
<paulk-collins> right
<paulk-collins> I am fully aware of that part :)
<javier__> paulk-collins: Ok, sorry for stating the obvious then
<javier__> I'm just trying to understand what your goal is :)
<paulk-collins> javier__, oh don't worry, I would certainly have liked to hear about it if I hadn't known about it!
<paulk-collins> Well, I'm interested in running devices with free software, so having free bootloaders is part of that
<paulk-collins> sadly, most exynos chromebooks don't qualify
<sjoerd> tbh i just see the bl1 as essentially part of the ROM
<sjoerd> Or do you hae SoC for which you can get the ROM code ? :)
<javier__> sjoerd: agreed
<javier__> just like most HW have also internal firmwares so in practice is imposible to not run proprietary software
<paulk-collins> sjoerd, well, I don't see it being part of the ROM code being any less of an issue to be honest
<sjoerd> but yeah the bl1's most folks ship only chainload signed SPLs which is very annoying
<paulk-collins> of course
<javier__> sjoerd: IIRC, that's not the case for the Chromebooks (i.e: you can replace the SPL if you want)
<paulk-collins> but some devices perform better than others regarding to freedom, so I prefer to focus on the ones that are better
<sjoerd> javier__: indeed
<paulk-collins> so if we can limit non-free software to burned bootrom code, the better :)
<sjoerd> oh sure
<paulk-collins> also, having a non-free components in the spi flash makes it difficult to have free software distributions for that (e.g. libreboot)
<paulk-collins> (even though in practice we can only replace part of the flash contents, it's always better to ship a full images)
<paulk-collins> s/images/image/
<sjoerd> oh sure it's tedious indeed
<javier__> paulk-collins: yeah, it's annoying indeed
<javier__> paulk-collins: but I think one has to choose his/her battles :)
<paulk-collins> heh :)
<javier__> paulk-collins: I find more annoying for example the lack of mali EGL sources
<paulk-collins> indeed, that's a major drawback…
<sjoerd> yup
<sjoerd> And if firmware makes you unhappy, the one for e.g. the wireless card is probably more bothersom then the bl1 :)
<paulk-collins> I use an external ath9k_htc
<javier__> sjoerd: exactly, that's what my point :)
<paulk-collins> and well, more bothersome, I don't know: it's not hard to do without the wifi firmware, but it's really hard to do without BL1 ;)
<javier__> at some point we have to draw the line of what is "HW"
<javier__> sjoerd: and IMHO the BL1 almost is as you said
<paulk-collins> Well, I do consider non-free hardware to be as much of an injustice and a problem as non-free software is…
<paulk-collins> so I don't really care about setting boundaries
<javier__> paulk-collins: agreed, but that's why I said that I prefer to choose my battles :)
<paulk-collins> I understand
<javier__> paulk-collins: the Chromebooks for example are remarkably open for being a consumer device
<paulk-collins> indeed, they are
