Can't reply to josh directly.

There are two problems. 1st a legal one 2nd a technical. The technical one
is being resolved by the community. With little help from Allwinner. I say
a "little help" not "no help". When A64 is bootable by uboot then it might
by a possible EOMA68 target, from firmware perspective.

AFAIK:

The early boot loader in AW SOC's is BROM: http://linux-sunxi.org/BROM. It
built in on production and cannot be modified, hence ROM: Read Only Memory.
The ROM can be read however. The BROM is the first software loaded in the
chain. Currently it can load the AW Boot0 or U-Boot SPL.

After Boot0 comes Boot1. After U-Boot SPL comes U-Boot.

boot1 is a AW modified U-Boot.

So if i'm correct there is a for stage boot sequence.
1. BROM (Find and start bootable software)
2. Boot0/U-Boot SPL (Init Hardware like memory, uart, clocks, regulators
then load the next stage)
3. Boot1/U-Boot (Init perhipials and load the final stage: Linux)
4. Linux

The SoC have a tiny bit embedded RAM (SRAM). Just large enough for boot0 os
U-Boot SPL which init's the external RAM (DRAM) and load the next boot
stage to is and starts it.

The legal problem is different. And the cannot, easily,  be fixed
afterwards. AW has sold/is selling SoC's including binary, modified, copies
of GPL software. U-Boot (boot1), FFMpeg(cedar) and few other.

While in China this is not a big, legal, problem. In most other countries
this is plain illegal.

So if I were to buy hardware from AW along with the software they provided
and resell it I would be making three violations.
1. Selling illegal software
2. Buying illegal software
3. Helping another parties sell illegal software

And anyone reselling my products would face the same issues

And once done it cannot be undone, damage has been done. But as long as
nobody complains I can keep doing it. That's the way the world works. But
it still would put me at risk of prosecution, import blokkades, etc.

Every country weighs violations differently. In some countries I would be
part of criminal cartel, not very hard to imagine.

I can try to rectify and publish afterwards. But I can still be held
accountable for damage done.

I can try sending out replacement software "stripped" of the GPL violation
stuff. But I can still be held accountable for damage done.

I can try sending out replacement software masking the GPL violation stuff.
But I can still be held accountable for damage done and being done.

When I'm reselling I don't have any of the options above. I can only hope
AW wil help me. But as they already have my money I'm of little interest i
guess. I could spend a lot of time and money to rectify it myself, but as
you can see with the sunxi community that probably be too slow and
expensive. But for Allwinner it would be almost cost-less to do.

GPL software is free but comes with some, legally binding, restrictions.
When your not abiding those restrictions you are violating a legal
contract. Hence the illegal software. Contracts do not always require
signatures. Contracts are a formal agreement of terms.

Look at Oracle, Samsung, Google, SCO, etc. They have done all of the above.
And now they are 'actively' changing their ways. But they are big enough to
stall. SCO tried and died. It's never pretty.

Luke's EOMA68-A20 is something unheard of. Buying hardware without SDK and
probably support. And selling it with a totally free stack of software and
firmware.

That and no co-processors which can work independently from your system to
help/spy/corrupt you.

The only exception is the BROM. But that can/should be considered hardware
as it cannot be changed and is build-in. Plus the bonus that it can be read
and verified.
