<f_> So I'll try getting TF-A up and running on the gxbb.
<f_> Wish me good luck......never reverse-engineer anything like that. =)
<f_> I'm sure I'll learn many things about ARM by working on TF-A.
<HackerKkillinghi> :0
<f_> ?

<f_> Well.
<f_> What I *actually* want to do is reverse-engineer utils used to create an FIP.
<f_> IIRC acs.bin is supposed to be GPL'd......so it seems like WeTek is violating the GPL right?
<f_> When I'm done I'll create a PR for meson-tools.
<f_> Most likely.

<f_> Oh. Before I forget
<f_> linux has a regression where ethernet is broken on some device trees
<f_> (gxbb)
jacobk has joined #linux-amlogic
<f_> But I guess y'all already know and know the fix to it too.

<f_> narmstrong: I see in the fip.bin produced by fip_create that there's a huge gap between bl30, bl31, and u-boot
<f_> Here's the output of fiptool (taken from TF-A):
<f_> SCP Firmware SCP_BL2: offset=0x4000, size=0xD400, cmdline="--scp-fw"
<f_> EL3 Runtime Firmware BL31: offset=0x14000, size=0x18130, cmdline="--soc-fw"
<f_> Non-Trusted Firmware BL33: offset=0x30000, size=0xAD118, cmdline="--nt-fw"
<f_> Should be self-explanatory.
<f_> While using fiptool to create an fip, there aren't such gaps. Are they necessary on gxbb?
<f_> narmstrong: Ok that's a very stupid question lol
<f_> The offset of each payload is in the header =)
<f_> !read the manual!
<f_> narmstrong: You did tell me gxbb uses custom UUIDs right? well...I don't see any.
<narmstrong> Honestly I know little on the gxbb fip packaging, meson-tools is your friend here, afaerber did the r-e job
<f_> I don't think they did anything related to fip_create.
<f_> And I think I'm starting to know why.
<f_> narmstrong: What if.....the gxbb fips were standard?
<f_> Anyways, since you know little on gxbb fip packaging I won't annoy you more =)
