No, unfourtunately.

I like how it works, too.

unlike other conferences (e.g. LibrePlanet) everyone gets to watch the same thing, for example.

previous victim was an old set-top box..and it's currently booted to linux w/ U-Boot SPL.

Just made a quick loop to check for unused register #defines

The joys of POSIX shell :)

and that returns a long, long list of unused defined registers

Of course there are some false-positives such as DMC_HEVC_SEC_READ_CTRL
10:13
<
f_ >
but DMC-related region registers are the only false-positives.
10:13
<

I'll remove all these and thus shrink dram-gx.h
10:13

f_ >
Should make it easier to port to gxl after that

(as at this point we can just change the base address of some of these)

haha Pi5 has all the proprietary firmware in SPI

non-writable to pass FSF requirements?
14:01

I miss the old Pi boards where the firmware was on SD card

I still don’t understand what is so secret to have this firmware not open source
14:04

f_ >
apparently it's because of broadcom

narmstrong: especially since i think some people started rewriting floss?

Same for the config.txt, it was ok for rpi1 but honestly today it’s dumb

I also don't understand why RPi only gives partial schematics :P
14:15
<
f_ >
SoC vendors just don't want people to look at how their SoC works..which should be a basic right
14:16
<
f_ >
instead they say 'ok here's this proprietary firmware you can use to boot. use it and everything will be fine'
14:16
<
f_ >
'don't bother us with open source'
14:16

Until some weirdo goes on his way to reverse-engineer that firmware

Am now looking at the S905X datasheet to see which registers they moved to other addressed
