Add pr_fmt() macro
This macro can be overridden in source files (before including common.h) and can be used to specify a prefix for debug and error messages. An example of how to use this is shown below: #define pr_fmt(fmt) "foo: " fmt #include <common.h> ... debug("bar"); The resulting message will read: foo: bar Acked-by: Simon Glass <sjg@chromium.org> Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Simon Glass <sjg@chromium.org>
