<narmstrong> did someone try poulecaca's FIP tools ?
<poulecaca> yes, I did :)
<narmstrong> poulecaca: sure you did ! On which board ?
<poulecaca> lepotato
<narmstrong> good :-)
<poulecaca> adema_: did also but on lepotato
<adema_> it works fine
<adema_> as far as i can tell
<narmstrong> it would be useful to integrate it into meta-meson, I'll add it on the TODO list...
<adema_> whats meta-meson ?
<adema_> narmstrong, i might also help for buildroot integration ? i saw some comment on the ml saying because the tools were propritary closed-source binary it was kind of complicated to integrate it with buildroot
<adema_> s/i/it
<narmstrong> adema_: you will still have an issue with the redistribution licence of the bl2, acs.bin, bl301 and bl31 binaires
<narmstrong> *binaries
<adema_> yeah i guess
<narmstrong> we asked amlogic to clarify it
<narmstrong> adema_: but I need to resent my patchset without u-boot, but you could still integrate the tool until we have a proper licence for the binaries
<adema_> lets just reverse and open source all the things :p
<narmstrong> easy :-)
<narmstrong> the DDR init part will be the easiest I think :-D
<narmstrong> poulecaca: yep this one
<narmstrong> the gxbb part could use afaerber's tools aswell, but I'm so lazy...
<vagrantc> bl31.bin can come from upstream arm-trusted-firmware at least for gxbb
<poulecaca> yes and for gxl there is also a WIP
<poulecaca> Also, I think that the SCP firmware is a modified version of https://www.chromium.org/chromium-os/ec-development that runs on a Cortex-M3. But I haven't dug enough to be sure of that.

<ldevulder> narmstrong, I just try to boot my vim1 with latest rc1 u-boot and something goes wrong, I just had a: "Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000"
<ldevulder> need to check why (was ok with my previous u-boot version with your patches and mine but the old ones)

<ldevulder> looks like in efivars, so maybe not related to meson changes

<ldevulder> more in efi, I think I will check this with EFI maintainer in u-boot :)\

<ldevulder> narmstrong, definitely in the last UEFI commit, boots ok with 'noefi' option on last u-boot, so looks like in commit f388e3bed7318efe97058b673801dda6f563d319
<ldevulder> reverting the commit did the job, so yes issue in this, I will try to quickly check and ask Alexander Graf for this

<ccaione> ldevulder: `7a82c3051c8fdc5c6a91db1f50303ad18c36621f is the first bad commit`
<ccaione> just FYI
drieschel has quit [Quit: drieschel]
<ldevulder> ccaione, this one seems to not hurt in my case but maybe yes
<ccaione> did you bisect as well?
<ldevulder> oh maybe it is part of the whole pull, so yes could be this one
<ccaione> yeah, it is part of the merge
<ldevulder> ccaione, not had time yet to bisect yet, I will try tomorrow if I have little bit free time
<ldevulder> I just send the bootlog to Alexander, maybe he can find quickly the issue (at least more quickly than me :)) and if not I will try commit by commit to find the bad one
<ccaione> ldevulder: that commit is the result of bisection already

<narmstrong> ldevulder: if you want to test replace `runtime_pages = (runtime_end - runtime_start) >> EFI_PAGE_SHIFT;`by `runtime_pages = (runtime_end - runtime_start) >> 16`; in lib/efi_loader/efi_memory.c
