Get more informative output from cbmem.py
This is a cosmetic change which formats timestamp information retrieved by cbmem.py. Instead of printing timestamps in a single line, print them one per line and add time (in us) elapsed since the previous timestamp. time base 4149594, total entries 18 1:56,928 2:58,851 (1,923) 3:175,230 (116,378) 4:175,340 (109) 8:177,199 (1,859) 9:214,368 (37,168) 10:214,450 (81) 30:214,462 (11) 40:215,205 (743) 50:217,180 (1,974) 60:217,312 (132) 70:436,984 (219,671) 75:436,993 (8) 80:441,424 (4,431) 90:442,487 (1,062) 99:553,777 (111,289) 1000:556,513 (2,736) 1100:824,621 (268,107) Change-Id: I0d25cafe766c10377017697e6b206276e1a92992 Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Reviewed-on: http://review.coreboot.org/1716 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.
