<CyReVolt> <f_> "doing so is pretty risky Imo" <- I am aware of that, I just want to document those things.
<CyReVolt> Almost all SoCs nowadays have efuses for "secure boot" shenanigans. ^^
<CyReVolt> I've added those notes to the issue, thanks :)

<f_> > <f_> > .ddr_set_version = 2,
<f_> ok that's actually normal

<f_> What I find strange is .. the parsed acs looks strange
<f_> Okay, ddrs looks fine...
<f_> but `plls` is mostly all zeroes
<f_> Only plls.cpu_clk is set to something
<f_> 🤔
<f_> Mi TV Stick is certainly full of surprises

<f_> ok now I remember where I saw a lot of EFUSE stuff. Look for "EFUSE" in arch/arm/cpu/armv8/gxl/firmware/scp_task/secure_apb.h for some interesting stuff
<f_> There might also be some interesting stuff in old gpl amlogic BL2 sources https://git.vitali64.duckdns.org/archive/amlogic-bl2.git/tree/
<f_> heh look what I found regarding @KEY
<f_> I found the same @KEY stuff in bl33/board/amlogic/gxl_p241_v1/aml-user-key.sig
<f_> (not identical, but I saw the @KEY magic thing) I wonder what they're for

<f_> Something interesting ... while looking at a dump of 0xd9000000-0xd9014000 from Mi TV Stick I noticed.... leftovers of BL30??

<f_> It's always great when there are decrypted leftovers.. guess I don't have to figure out decrypting BL30 :D
