X-Git-Url: http://git.dujemihanovic.xyz/img/static/gitweb.css?a=commitdiff_plain;h=615d84b6ce0cf51363292ca527644d820aa0a813;p=u-boot.git

test: Move some SPL-loading test-code into sandbox common

This code is useful for loading an image in sandbox_spl so move it into
a place where it can be called as needed.
