From 7379d0b05b11519ecbe586017939ed1b0a6871c4 Mon Sep 17 00:00:00 2001
From: Ayan Kumar Halder
Date: Fri, 17 Dec 2021 15:48:55 +0000
Subject: Refactor uboot-script-gen

Extract some of the functions from uboot-script-gen into common.
This will be sourced by disk_image(in subsequent patch) which will
invoke the functions for generating dtb.
common will have access to all the environment variables defined in
the Imagebuilder config file as described in README.md
