Freescale and Lua copyrights

Freescale and Lua copyrights

[Michael Jones]

All,

I am working on a Freescale iMX6 hal and various other additions like telnet, lua, etc.

I have two copyright issues. One, the Freescale copyright, and second, the Lua copyright.

I would like to avoid recoding all the iMX6 SDK code. 

I am using the register files (over 100) and various parts of the C code. Furthermore, in the case of register include files, they are auto generated by Freescale and today there are 3 revisions for 3 iMX6 cores (1,2,4 cores), which is 9 different sets of files. I can write scripts that handle renaming of #defines and functions such that future revisions can be quickly incorporated. Also, keeping close to the SDK allows me to leverage updates to the SDK, diff code, etc.

I would like to resolve this quickly so I can plan for evolving the current semi-hacked working version of the iMX6 hal to a version suitable for incorporation (desired), or if the effort is too large, remain independent (not desired). It is difficult to know where to invest time without knowing what will be allowed.

Can you accept this Freescale Copyright into the official eCos code base:

I have a Lua 5.2.3 port that is fully functional. It has minimal modifications. It is called from my telnetd package (will be submitted to eCos with full copyright assignment when mature). There is no way to rewrite this to avoid the copyright, so will you accept this Lua Copyright into the official eCos code base:

Unfortunately that isn't a license, that's a copyright message with all rights
reserved, and a disclaimer. "All rights reserved" means there is no right to
copy, modify, redistribute, etc. You will need to talk to Freescale to get
that resolved, or to recode it, sorry. Note that this restriction on
redistribution applies whether or not you contribute it!

As has happened before, I suspect it's just sloppiness on Freescale's part and
they did intend it to be fully re-distributable, but with what it says above
that legally isn't the case.

Yes, the Lua licence is fine. The only thing I would request is that a note is
made in documentation reminding users of this license, since it won't be the
normal eCos one.

Good luck with Freescale!

Jifl,

I did a bit of research, and I found that when you download the iMX6 SDK, there is a LICENSE.txt in the root directory with the following text:

The previous text I sent is in the individual files.

Does this satisfy the requirements and allow the code in?

I expect that is fine then, but you will need to paste that into the top
of each of the individual files in that case so that there's no uncertainty.

Also, a mention of this in some package documentation would be valuable,
thanks.

Subject to code review, I think so.

Jifl,

Ok. I have also asked Freescale for a more formal/public statement or to put the statement in the files themselves. Let's see if I can get any traction from that.
