+
+ Process a console log for EXPECTed test related messages to either
+ highlight expected devicetree unittest related messages or suppress
+ the messages. Leading console timestamps will be stripped.
+
+ Various unittests may trigger kernel messages from outside the
+ unittest code. The unittest annotates that it expects the message
+ to occur with an 'EXPECT \\ : text' (begin) before triggering the
+ message, and an 'EXPECT / : text' (end) after triggering the message.
+
+ If an expected message does not occur, that will be reported.
+
+ For each expected message, the 'EXPECT \\ : text' (begin) and
+ 'EXPECT / : text' (end), 'text' will contain the message text.
+
+ If 'EXPECT \\' (begin) and 'EXPECT /' (end) lines do not contain
+ matching 'text', that will be reported.
+
+ If EXPECT lines are nested, 'EXPECT /' (end) lines must be in the
+ reverse order of the corresponding 'EXPECT \\' (begin) lines.
+
+ 'EXPECT \\ : text' (begin) and 'EXPECT / : text' (end) lines can
+ contain special patterns in 'text':
+
+ <<int>> matches: [+-]*[0-9]+
+ <<hex>> matches: (0x)*[0-9a-f]+
+
+ 'EXPECT \\' (begin) and 'EXPECT /' (end) lines are suppressed.
+
+ A prefix is added to every line of output:
+
+ 'ok ' Line matches an enclosing EXPECT begin/end pair
+
+ '** ' Line reports $script_name warning or error
+
+ '-> ' Line reports start or end of the unittests
+
+ '>> ' Line reports a unittest test FAIL
+
+ ' ' Lines that are not otherwise prefixed
+
+ Issues detected in CONSOLE_LOG are reported to STDOUT, not to STDERR.
+
+ Known Issues:
+
+ --line-num causes the CONSOLE_LOG line number to be printed in 4 columns.
+ If CONSOLE_LOG contains more than 9999 lines then more columns will be
+ used to report the line number for lines greater than 9999 (eg for
+ lines 10000 - 99999, 5 columns will be used).
