Subject: ARM: fix LTO for apf27
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=28d476eada6b49fdbd331171c6a487466e709a66;p=u-boot.git

ARM: fix LTO for apf27

When apf27_defconfig is built with LTO, linking complains about
undefined reference to `nand_boot`. This is because it is referenced
from inline assembly. Make it visible.
