      uwb: improved MAS allocator and reservation conflict handling · 5b37717a
      Stefano Panella authored
      Greatly enhance the MAS allocator:
        - Handle row and column reservations.
        - Permit all the available MAS to be allocated.
        - Follows the WiMedia rules on MAS selection.
      
      Take appropriate action when reservation conflicts are detected.
        - Correctly identify which reservation wins the conflict.
        - Protect alien BP reservations.
        - If an owned reservation loses, resize/move it.
        - Follow the backoff procedure before requesting additional MAS.
      
      When reservations are terminated, move the remaining reservations (if
      necessary) so they keep following the MAS allocation rules.

      uwb: add basic radio manager · 6fae35f9
      David Vrabel authored
      The UWB radio manager coordinates the use of the radio between the
      PALs that may be using it.  PALs request use of the radio with
      uwb_radio_start() and the radio manager will start beaconing if its
      not already doing so.  When the last PAL has called uwb_radio_stop()
      beaconing will be stopped.
      
      In the future, the radio manager will have a more sophisticated channel
      selection algorithm, probably following the Channel Selection Policy
      from the WiMedia Alliance when it is finalized.  For now, channel 9
      (BG1, TFC1) is selected.
      
      The user may override the channel selected by the radio manager and may
      force the radio to stop beaconing.
      
      The WUSB Host Controller PAL makes use of this and there are two new
      debug PAL commands that can be used for testing.
