Clarification on the VIM Source codes

Hi,

There were some branches provided on the mainline in git hub code https://github.com/khadas/linux/branches/active

I was confused on few items and would like to get clarified.

  1. Does ubuntu4.9 supports both VIM1.2 and VIM1.2 Pro boards as well ?
  2. Is “buildroot-aml-4.9” is mini version with bare minimal rootfs and configurations ? What is the difference between ubuntu/android/buildroot-aml-4.9

Looking for some simple kernel/rootfs with provision use WiFi/LAN functionalities.
