--- Comment #16 from Olivier Berthier <olivierx.berthier at intel.com> ---
Thanks, this resolve the problem.
The symbolic link and the md5sum were correct, but after reconfiguring the
kernel the guc is correctly loaded :

# cat /sys/kernel/debug/dri/0/i915_guc_load_status 
GuC firmware status:
        path: i915/skl_guc_ver4.bin
        fetch: SUCCESS
        load: SUCCESS

        version found: 4.3
        header: offset is 0; size = 128
        uCode: offset is 128; size = 127936
        RSA: offset is 128064; size = 256
