12 Binary descriptors are created by using the ``DEFINE_BINDESC_*`` macros. For example:
35 Binary descriptors are implemented with a TLV (tag, length, value) header linked
37 but generally the descriptors are linked as close to the beginning of the image as

70 Binary descriptors are always created by the ``BINDESC_*_DEFINE`` macros. As shown in
