DM6446 is quite different from OMAP-L138. Both AM180x and DA850 are just
derivatives of OMAP-L138.

Anyway, DM6446 is no longer supported, as it's a very old platform.

So how hard is it to get ti816x machine support moved up into Dylan (or master)?  I've always had machine support for the branches I used in the past ... now I find myself needing Dylan or even master and there is no ti816x support there.

Is it not there just because nobody had hardware to test it?  If so, I'm game to add it with some guidance :)

[CEM] Generally not too hard.  You can often start with the old arago machine and move that in with some cleanup.  Then you will need to move/create the bootloader and kernel recipes as well, again looking for cleanup.  That should give you a basic working system.  The main issue is that someone needs to be signed up to keep those recipes working and up to date.  That is what is missing in most cases is a maitainer.

Even better, for you use I would recommend looking at commit c586bd9a66 which is the one that removed these configs and then add back the pieces you need.

Regards,

Brian
