Some lines of the output are not worth testing, or not worth testing in their entirety. For example, when checking a hex dump we know that the hex-dump routine can display ASCII so we only need to check the hex bytes, not the ASCII dump. Add a new test macros which can check only part of a console line. Sometimes it is useful to skip a line altogether, so add a macro for that also. Signed-off-by: Simon Glass <sjg@chromium.org>
