A: Dropping dynamic-layer/selinux/android-tools over deafult as per 
     https://lists.openembedded.org/g/openembedded-devel/topic/117415388
- Looked at this (topic/117415388 discussion), the discussion leds to removal of only config file which was duplicated 
   Recipes are not to be dropped 
   The duplicated config files were removed by Commit-Id: c276518790 in meta-openembedded (master)

B:
Is the proposed patch dependent on "selinux"
- This implementaion is not directly depending on SELINUX but dpendent on higher version of Android
   The higher version is available under dynamic-layer/selinux and that why the changes on dynamic-layer
 
C: Recheck if selinux dependcy is still there in android-tools
     If no selinux dependcy , move it to default meta-oe layer 
- Working on this and will share the observation 

- Will use weak assignment for preferred_version in V3 of patch 

Thanks ,
