Subject: Makefile: generate symbol list from u-boot
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=7ed4848bb86c562707a02333a6f2f816d0e48955;p=u-boot.git

Makefile: generate symbol list from u-boot

This information may be useful for both debugging, and processes that want
to perform simple forms of introspection on the U-Boot binary, such as
determining the set of "ut" subtests that are compiled in.
