Re: PACKAGES_PATH in !include path in Dsc files

["Gao, Liming" <liming.gao@intel.com>]

Hi, 
  You can directly include it. BaseTools will search it from WORKSPACE and PACKAGES_PATH. So, you only need to set edk2-platforms directory into PACKAGES_PATH env. 

!include Silicon/NXP/<Silicon Name>.dsc

Thanks
