OK, let us back the truck up, so to speak. This particular version of
the file has an odd license. Looking at
https://android.googlesource.com/kernel/lk/+/master/app/aboot/aboot.c
[54963a727d3e4ed1e945c7ec012b5cc5de168ac5] and it has the normal
BSD-3-Clause text. Lets grab and adapt that so we can drop the license
issue.

Oh, but you can implement that part into the file with a subsequent patch, no ?

Can you poke around more for a version of aboot.c that has sparse image
support and comes more directly from google.com and thus hopefully
someone caught the rather strange license text changes?

I have previously spent hours looking for:
(1) sparse_format.h -- which we now have (thanks to Colin Cross)
(2) any implementation of the "while()" loop which parses this "sparse
format"
This implementation, in aboot.c (also recommended by Colin Cross), is
also available from "Code Aurora" -- but it has the same wording as the
"Linux Foundation" file; I have not found it anywhere else.
I cannot spend any more time on this license issue....
Please keep me informed of the outcome!
Thanks, Steve

... and, this is how it ends. Again, legal crap proved to be a death sentence
for a patch and carried with it an excessive amount of wasted effort.

I certainly hope not 100% dead!!!!
If U-Boot would accept (the currently one-off) BSD-3L-Clause, then this
could live!

Any progress on the license wording?
(1) create BSD-3L-Clause
or
(2) leave the original text in place, and add the following:
* NOTE:
* Although it is very similar, this license text is not identical
* to the "BSD-3-Clause", therefore, DO NOT MODIFY THIS LICENSE TEXT!
or
(3) ???
Please let me know!
Thanks, Steve

OK, sorry for the churn. After you pointed out the other differences, I
re-asked legal who look a closer look (they started with my "they just
changed this one thing..") and do believe the license is GPL compatible
but it is NOT BSD-3-Clause. So I think rather than make a one-off tag
lets just leave the full text and insert a note saying it's a slightly
different wording from normal BSD-3, and we inherit this license as-is
from Android.

comments:
(1) I suspect that the "Linux Foundation" has adopted this "license
text", and I also suspect that we will likely getting more code from
there; thus, while it is one-off right now, I 'm guessing that will
change...
(2) so "v3" will leave the original text in place, and add the following:
* NOTE:
* Although it is very similar, this license text is not identical
* to the "BSD-3-Clause", therefore, DO NOT MODIFY THIS LICENSE TEXT!
Is this what you would like?
( my preference would be to add the BSD-3L-Clause ... )
Thanks, Steve
