Broadcomm's latest Bluetooth SoC has wireless charging on board
The SoC utilizes the A4WP (Alliance 4 Wireless Power) standard, which is a slightly different interpretation of other well-known wireless charging technologies such as Qi. The A4WP standard allows users to charge multiple devices from a single transmitter due to its larger charging distance.
The 6.5 x 6.5 mm chip also comes with an an ARM Cortex M3 processor and integrated support for the Bluetooth Smart technology. Apart from this, Broadcomm's processor is optimized for lower power consumption, which will, allegedly, prolong the battery life of the gadget it powers even more.

Cortex M3 processor? Never heard of it. Can anyone provide the performance difference between this and Cortex-A5/A7/A9/A15?

You are totally wrong. Cortex-M3 isn't main processor on main SoC, but processor of Bleutooth SoC. Okay? :-)
Cortex-M3 is processor for specific tasks, not for all task. This is in truth bluetooth coprocessor. :-)

Okay, I guess I am misinformed. This article confuses me, though. What exactly is this chip for? Is it simply a Bluetooth chip or something else?

Yes, you're correct. This SoC (it's chip with own processor and memory and other things) provides to device bluetooth functionality. :-) And this particular also Qi wireless charging. :-)
