Description

Nordic has released a new series of microcontrollers with radio modules, nRF53, with its flagship nrf5340

It would be great to have support for them; relevant sub-items are:

• Support for the new radios. Most urgent is probably Bluetooth (as they offer new BLE features like isochronous transfers).

  As nimble already supports them, might just be a nimble update and some glue code away?

• Multiprocessor support.

  I don't think we have to go all in immediately, even though asymmetric multiprocessing should be a long-term goal. Being able to run on the radio core alone should already get us some of the way.

Relevant boards

Boards that should be easy to add once the family is in are the thingy:53, nrf5340-dk and nrf5340-audio-dk.

(Generally, BLE audio is a really big new item in these, and that will be in high demand, judging from feedback from a hearing aid technician).
