12 This provides a way to record console output (and provide console
Robert P. J. Daye9c629c2016-08-31 12:49:13 -040013 input) through circular buffers. This is mostly useful for testing.
Simon Glass1bb49232015-11-08 23:47:48 -070014 Console output is recorded even when the console is silent.
15 To enable console recording, call console_record_reset_enable()

172 Defining CONFIG_PRE_CONSOLE_BUFFER will cause U-Boot to

175 if it overflows, earlier output is discarded.
