18 U-Boot's logging feature aims to satisfy this goal for both users and

50    LOGC_ARCH	- Related to architecture-specific code

52    LOGC_CORE	- Related to core driver-model support
53    LOGC_DT	- Related to device tree control
59 The following options are used to enable logging at compile time:
62    CONFIG_MAX_LOG_LEVEL - Max log level to build (anything higher is compiled
64    CONFIG_LOG_CONSOLE	- Enable writing log records to the console
74 U-Boot has traditionally used a #define called DEBUG to enable debugging on a
75 file-by-file basis. The debug() macro compiles to a printf() statement if
81 The logging facilities are intended to replace DEBUG, but if DEBUG is defined
83 statements will result in output to the console and this output will not be

100 Filters are attached to log drivers to control what those drivers emit. Only
101 records that pass through the filter make it to the driver.
109 If no filters are attached to a driver then a default filter is used, which
110 limits output to records with a level less than CONFIG_LOG_MAX_LEVEL.

200 Provide a command to access the number of log records generated, and the
201 number dropped due to them being generated before the log system was ready.
205 Enhance the log console driver to show level / category / file / line
208 Add a command to add new log records and delete existing records.
210 Provide additional log() functions - e.g. logc() to specify the category
