From 947c626dc5bfbc232cc0f41d16fa213a885ad234 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Thu, 14 Jan 2016 13:02:03 -0500 Subject: vsprintf.c: Always enable CONFIG_SYS_VSNPRINTF Enabling this function always removes some class of string saftey issues. The size change here in general is about 400 bytes and this seems a reasonable trade-off.
