we have an am335x based custom board that use for our Project. At the moment only a customized version of uboot-2013.01.01 supports this board. As we use Yocto toolchains and we plan to upgrade to latest Yocto-2.0 that comes with GCC5.2.
I would like to be able to build this custom old version with newer toolchains.
For that I added from new u-boot the file : include/linux/compiler-gcc5.h
But still having some compile errors :

Any chance to backport GCC5 support to old u-boot version ?
Perhaps this helps "inline: use the gcc inline version instead of the c99 one." http://lists.denx.de/pipermail/u-boot/2014-May/180709.html
