    <thetext>The variable &quot;KFEATURE_COMPATIBILITY&quot; is not currently well defined, but does appear in various feature fragments. Before this can be properly documented, we need an explicit definition of how this is meant to be used.</thetext>

    <thetext>  - the two ways that things are declared &apos;optional&apos;, is largely historical.
    before we had KFEATURE_COMPATIBILITY, -enable meant &quot;you can turn
    this on if you want&quot;, so not having to update all those fragments
    with the new field, and keep them working with existing front ends
    was the driver behind keeping it around. I won&apos;t be suggesting it
    to people for new fragments.

  - &quot;optional&quot;: means that is truly is something that you can turn on
    for any board, any arch at any time. It&apos;s a software construct that
    carries some sort of overhead or optional functionality. As such, 
    we don&apos;t have it on all the time .. but a BSP or end user might want
    to do so.

 - I&apos;ll be documenting all the options for KFEATURE_COMPATIBILITY 
   options. In the end, the list of values is extendible, since the
   enforcement of values can be either by front ends, or by the
   meta-series processing scripts. Both which can change to match
   new values.

   Right now it is:
    
     - board
         - board:&lt;specific board names (comma separated)&gt;
     - arch
         - arch:&lt;specific kernel arches(comma separated) &gt;
     - all


   And these mean just what you&apos;d think, that they have board or 
   architecture specific requirements (ports) and that they may only
   work for a few specific arches/boards. Without the : and list of
   boards are arches, it is a big vague/generic and should be treated
   as a warning vs a hard error.</thetext>
