/* Debug macros to runtime filter the debug messages sent to the console.  In
 * general, there are four forms of the debug macros:
 *
 * [a-z]info() -- Outputs messages to the console similar to printf() except
 *    that the output is not buffered.  Output is only generated if
 *    CONFIG_DEBUG_INFO is defined.  The info macros are intended for
 *    verbose "informational" debug output.  If you enable CONFIG_DEBUG_INFO,
 *    then very chatty (and often annoying) output will be generated.
 *
 *    The first character of the macro name indicates the system system
 *    (e.g., n=network, f=filesystm, etc.).  If the first character is
 *    missing (i.e., _info()), then it is common.  The common _info() macro
 *    is enabled simply with CONFIG_DEBUG_INFO.  Subsystem debug requires an
 *    additional configuration setting to enable it (e.g., CONFIG_DEBUG_NET
 *    for the network, CONFIG_DEBUG_FS for the file system, etc).
 *
 *    In general, error messages and output of importance use [a-z]err().
 *    [a-z]err() is implementation dependent but usually uses file descriptors.
 *    (that is a problem only because the interrupt task may have re-
 *    directed stdout).  Therefore [a-z]err() should not be used in interrupt
 *    handlers.
 *
 * [a-z]warn() -- Identical to [a-z]info() except that it also requires that
 *    CONFIG_DEBUG_WARN be defined.  This is intended for important exception
 *    conditions that are potential errors (or perhaps real errors with non-
 *    fatal consequences).
 *
 * [a-z]err() -- Identical to [a-z]info() except that it also requires that
 *    CONFIG_DEBUG_ERROR be defined.  This is intended for important error-related
 *    information that you probably not want to suppress during normal debug
 *    general debugging.
 *
 * _alert() - is a special, high-priority, unconditional version that is really
 *    intended only for crash error reporting.
