From a1a38c4c6a0f73e8a9dc217c0e4e0ac483a89f25 Mon Sep 17 00:00:00 2001 From: Kim Phillips Date: Mon, 12 Dec 2011 14:59:16 -0600 Subject: [PATCH] crypto: caam - remove DECO access initialization code Access to the SEC4 DECOs (DEscriptor COntrollers) (for debug purposes) isn't supported or used, and its register access initialization code erroneously makes illegal i/o accesses that show up as errors when run under simulation. Remove it until proper support (via DECORR) is added.
