comments:
 - TPU can probably be tested using GPIO_CN with the GPIO logic analyzer
 - testing PWM is currently unclear; BSP also doesn't have PWM on Falcon
 - TPU
   - testing TPU with GPIO logic analyzer was successful

     - not needed. We have the generic fallback

     - should be changed to M

     - won't be upported because there are no users on the boards
