From bc85b25e5de17d714e8001cb3dc0feb66eac2750 Mon Sep 17 00:00:00 2001 From: Alessandro Rubini Date: Sat, 19 Dec 2009 19:45:43 +0800 Subject: hwrng: nomadik - Add hardware RNG driver The hardware random number generator by ST is used in both the Nomadik 8815 SoC and the U8500. It returns 16 bits every 400ns with automatic delay if a read is issued too early. It depends on PLAT_NOMADIK.
