This adds the powernv_get_random_darn function which utilises the darn instruction, introduced in POWER9. The powernv_get_random_darn function is used as the ppc_md.get_random_seed on P9. The DARN instruction can potentially throw an error, so we attempt to register the powernv_get_random_darn function up to 10 times before failing. Signed-off-by: Matt Brown <redacted>
Applied to powerpc next, thanks. https://git.kernel.org/powerpc/c/e66ca3db5917f4bcad039d3a3df9f1 cheers
