-Subject: [PATCH] newlib: memcpy: remove optimized version
-
-When creating messages packed to send over openamp we may need
-to do some copy in unaligned address, because of that we may
-not always use the assembler optimized version, which will
-trough a data-abort on aligned address exception.
-
-So, we may just use the version in string.h (the same used in
-optee-os) that will take care to check and use different
-optimization based on given source or destination address's.
-
-Upstream-Status: Pending
-Signed-off-by: Rui Miguel Silva <rui.silva@linaro.org>
