Configuration : what is magic

For Developers
#1

In ramips we got platform.sh

What is that magic about? where do we get that number and what its use?

eg:
youku-yk1)
[ "$magic" != "27051956" ] && {
echo "Invalid image type."
return 1
}
return 0
;;

0x27051956 is the magic number of uImage

The magic number verification in platform.sh is deprecated in OpenWrt master, and replaced with generic metadata verification.
