At present this function sits in its own file but it does not really justify it. There are similar string functions in vsprintf.h, so move it there. Also add the missing function comment. Use the vsprintf.h include file explicitly where needed. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
Overview
--------
The LS1043A Reference Design Board (RDB) is a high-performance computing,
evaluation, and development platform that supports the QorIQ LS1043A
LayerScape Architecture processor. The LS1043ARDB provides SW development
platform for the Freescale LS1043A processor series, with a complete
debugging environment. The LS1043A RDB is lead-free and RoHS-compliant.
