From mboxrd@z Thu Jan 1 00:00:00 1970 From: Albert ARIBAUD Date: Sun, 26 Feb 2017 16:29:32 +0100 Subject: [U-Boot] [PATCH] openrd: disable private arch memset, memcpy and libgcc Message-ID: <20170226152932.5628-1-albert.u.boot@aribaud.net> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de The switch to private LIBGCC causes 'undefined instruction' exception in at least the Open-RD Ultimate and Client, and quite probably the Open-RD Base as well. While debugging this issue, it appeared the switch to architecture-optimized memset and memcpy also causes the same exceptions. Until a fix to private libgcc and architecture-optimized memcpy and memset is mainlined, disable their use in all openrd configurations.
