There's a definition in stdint.h (provided by gcc) which will be more correct if available. Define CONFIG_USE_STDINT to use this feature, or USE_STDINT=1 on the 'make' commmand. This adjusts the settings for x86 and sandbox, with both have 64-bit options. Signed-off-by: Gabe Black <gabeblack@google.com> Reviewed-by: Gabe Black <gabeblack@chromium.org> Tested-by: Gabe Black <gabeblack@chromium.org> Reviewed-by: Bill Richardson <wfrichar@google.com> Rewritten to be an option, since stdint.h is often available only in glibc. Changed to preserve a clear boundary between stdint and non-stdint Signed-off-by: Simon Glass <sjg@chromium.org>
