/* The simple printf routines are just that, simple.  They are
   implemented in terms of putchar (or the callback) meaning that they
   can be slow if putchar is expensive.  They only support a limited
   number of output conversions, namely those for strings, integers
   and characters.  Notably missing are the floating-point related
   output conversions.  However, they use very limited memory, in
   particular, they don't use malloc.  This makes them ideal for use
   during early initialization and in fragile situations (e.g.,
   asserts and panics).  */
