The petalinux-package prebuilt command creates a
new directory named “pre-built” inside the directory hierarchy of the specified
PetaLinux project. This directory contains the required files to facilitate booting a
board immediately without completely rebuilding the project. This workflow is intended
for those who later create a PetaLinux BSP file for distribution using the petalinux-package bsp workflow. All AMD reference PetaLinux BSPs contain a prebuilt directory.
