Subject: spl: add __noreturn attribute to spl_invoke_atf function
X-Git-Url: http://git.dujemihanovic.xyz/img/static/%7B%7B%20%28.OutputFormats.Get?a=commitdiff_plain;h=a60d9686f21fdf2549858ca0e728bcef545d73d2;p=u-boot.git

spl: add __noreturn attribute to spl_invoke_atf function

spl_invoke_atf function will not be returned to SPL. Thus, we need to
set __noreturn function attribute to the function.
