This patch introduces a new device driver s390-trng for the s390 platform which exploits the new PRNO TRNG cpacf subfunction. The true-random-number-generator is accessible from userspace, by default visible as /dev/trng. The driver also registers at the kernel build-in hwrng API to feed the hwrng with fresh entropy data. This generic device driver for hardware random data is visible from userspace as /dev/hwrng. Signed-off-by:
