Folks,<br>
<br>
please take this patch as an attempt to renew old discussion or rather <br>
start a new one focused solely on importing new ARM CMSIS code which is <br>
(i) under Apache 2 license but (ii) without any NOTICE file.<br></blockquote><div><br></div><div>The absence of a NOTICE file is OK.

I hope technical advantages are huge and there is no hinder involved <br>
like with other possible Apache2 licensed projects with NOTICE file <br>
presented.<br></blockquote><div><br></div><div>My reading is that we would need to pass the NOTICE file along.

The patch itself is clear replace of existing files with a new files, <br>
plus required files added and old one not needed anymore removed.<br>
<br>
The patch was very lightly tested by building several ARM BSPs <br>
especially those affected by the change.<br></blockquote><div><br></div><div>Did you have any BSPs to actually test on?

Thanks for any comments!<br></blockquote><div><br></div><div>I'm happy with the update and think it is OK license wise.
