I still assume my patch is correct. I will look at this later this week. Xilinx toolchain which I use normally are microblaze for BE or microblazeel that's why proper flags are default options already that's why I didn't see any issue. Did you take toolchain from kernel.org? https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/ Thanks, Michal --=20 Michal Simek, Ing.
