14 This provides a way to record console output (and provide console
Robert P. J. Day57247d92016-08-31 12:49:13 -040015 input) through circular buffers. This is mostly useful for testing.
Simon Glass9854a872015-11-08 23:47:48 -070016 Console output is recorded even when the console is silent.
17 To enable console recording, call console_record_reset_enable()

127 help
128 Prior to the console being initialised (i.e. serial UART
129 initialised etc) all console output is silently discarded.
130 Defining CONFIG_PRE_CONSOLE_BUFFER will cause U-Boot to
131 buffer any console messages prior to the console being
132 initialised to a buffer. The buffer is a circular buffer, so
133 if it overflows, earlier output is discarded.

136 useful to be able to share the pre-console buffer with SPL.

143 The size of the pre-console buffer affects how much console output
144 can be held before it overflows and starts discarding earlier
145 output. Normally there is very little output at this early stage,
146 unless debugging is enabled, so allow enough for ~10 lines of
