Maybe barebox or plan9. They did manage to boot a modified firmware but there's still components that aren't yet removed. --it also removes all the modules from the images except RBE, KERNEL, SYSLIB, and BUP-- So the modules RBE, KERNEL, SYSLIB and BUP are still their and if you read correctly --It should be noted that ROM, RBE, and KERNEL are executed at the zero privilege level (in ring-0) of the MIA kernel.-- Has for the theoretical completely free firmware, only the future will tell us. But has I see things it would be faster to go on POWER and besides faster we are 100% sure that there isn't anything in the background that we don't know about. Because has time goes on the X86 exploration we found surprise after surprise.

They began to implement similar ME/PSP functions I unfortunately don't remember the name of it so if someone knows please post it. There's also the GPU problem, there is zero effort from allwinner to free their MALI GPU and worse they persecute those who try to reverse engineer it (see the LIMA driver developer) that's why no 100% free driver is available. But still recently there has been people who tries to do something about it. http://lists.phcomp.co.uk/pipermail/arm-netbook/2017-May/013845.html https://people.freedesktop.org/~cbrill/dri-log/?channel=lima&date=2017-06-23 I hope they'll be ok. If you are interested in ARM I suggest that you go on the ARM-netbook mailing list. http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook > > > --mtx >
