• Boards under "Zynq UltraScale+ MPSoC Board Support Packages" will use aarch64 ARCH
• Boards under "Zynq-7000 SoC Board Support Packages" will use arm ARCH
  
• Boards under "MicroBlaze Board Support Packages" will user arm microblaze

How does the script work?

Every release, all the Licenses and Source code of packages are published at http://petalinux.xilinx.com/sswreleases/

For example, In 2019.x the information is available below

http://petalinux.xilinx.com/sswreleases/rel-v2019/sources/

http://petalinux.xilinx.com/sswreleases/rel-v2019/licenses/

The Licenses and Source code published is a super set, the script fetches all the information from the published link.

The input of the script is a manifest file which indicates the Root File System components that are part of the BSP.

NOTE:

The script is meant to be used only with the published BSP from Xilinx. Any user customization of the BSP might need

the user to provide the source code manually. 

Exceptions:

udev-extraconf can be ignored as it is startup script of embedded Linux on target and does not have any source code related to it.
watchdog-init has the source script along with licenses in licenses
