I was looking for any Freescale ARM parts but found none. Freescale is now part of NXP but I imagine they will keep Freescales part names. I can’t seem to locate any Atmel ARM parts either.
Thanks for the heads up, I’m not surprised but was hopeful. Since I’ve been looking at the new PCB packages I haven’t found any that producing up-to-date libraries but then again I haven’t looked at the $5K and up packages. I find it a true disgrace that the manufactures can’t get it together and produce one interchangeable format that isn’t STEP. At any rate thanks for the offer on the Atmel parts but I’ll pass, the only part I was looking at was the SAM D20 that BOSCH stuck into their BNO055 sensor. I did check out the Silicon Labs parts, I wasn’t aware they were in the ARM market - they have pulled a ‘Freescale’ in that they have an Eclipse based IDE (Percision32) with ‘Processor Expert’ like tool, for free. The SiM3C look to be an interesting part with some I/O at 300ma.
Back to my KiCad learning, Thanks
There are a few places I look for symbols :
http://www.kicadlib.org/
http://www.kicadcloud.com/
https://www.snapeda.com/home
google search
After that, I figure I would better spend an hour creating my own part than searching the web. At least then I get a symbol designed to my taste, rather than the weird and wonderful other people come up with 
Digikey carry nearly 4 million parts, snapeda claim to have 25 million! The mind boggles at how any commercial CAD package could support a comprehensive set of parts, let alone an Open Source one. There is little commercial incentive for manufacturers to support someone else’s business. And if not STEP, what non-proprietary interoperable standards are there?
I see that vendors like RS and Farnell are now providing part libraries, as they are getting into CAD tools, but mainly because they want to lock you in to buying parts from them.
The manufactures footprints are the issue, the logical symbolic part changes for the project, the land pattern doesn’t. They designed the package knowing the issues of current/heat/cross-talk so they are the one to make recommend the land pattern. It doesn’t have to be a complex, twenty year endeavor, a simple XML listing with recommend pad size, 0,0 on pin 1 along with each pins x,y and direction of rotation and some sort rating based on an agreed upon lookup for each pins function. The majority of parts can be described this way with exceptions being the devices with odd shaped pads dealing with current or heat and they can be described without any issues. Tweaks to the land patterns based on board builders requirements and the application are a given but they are tweaks not hours spent double checking data sheets. With this new generation of design tools for embedded processors generating the pin numbers and function of each pin takes minutes and we should be able to produce the component from that. Freescale, Silicon Labs, ST Microsystem,
but the output is different on each of these applications. As an experiment I created the basic 28 pin QFN description and appended the description to the manufactures package documentation. The XML is 334 bytes without descriptions here is the version with descriptions:
I can’t get this in as XML::::
test.xml (1.1 KB)
The same technology could be applied to the component/logical symbol.

With that XML I created the footprint, solder mask and stencil (a few lines of code helped)
