From b612312816ffe41a3a7616aa00394ffb248cf91e Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 27 Jan 2020 08:49:54 -0700 Subject: console: Add a function to read a line of the output / eof When recording the console output for testing it is useful to be able to read the output a line at a time to check that the output is correct. Also we need to check that we get to the end of the output. Add a console function to return the next line and another to see how must data is left.
