clean: Remove images and temporary build files
image: Build an image (see below for more information).
Building images:
By default 'make image' will create an image with the default
target profile and package set. You can use the following parameters
to change that:
make image PROFILE="<profilename>" # override the default target profile
make image PACKAGES="<pkg1> [<pkg2> [<pkg3> ...]]" # include extra packages
make image FILES="<path>" # include extra files from <path>
make image BIN_DIR="<path>" # alternative output directory for the images
make image EXTRA_IMAGE_NAME="<string>" # Add this to the output image filename (sanitized)
