4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Michal Simek <michal.simek@xxxxxxxxxx> commit 18ffc0cce4ff947a2acc9b2e06ae5309a6e6fb43 upstream. The patch: "microblaze: Setup proper dependency for optimized lib functions" (sha1: 7b6ce52be3f86520524711a6f33f3866f9339694) didn't setup all dependencies properly. Optimized lib functions in C are also present for little endian and optimized library functions in assembler are implemented only for big endian version.
