ap RO verification: enable logging
When AP RO verification is attempted, a lot of thing could go wrong, and the operator would usually have very little insight into what's happening unless there is a terminal connected to the Cr50 console. This patch adds a new log event for registering the AP RO verification progress. The event payload is a single byte value, logging the following events: 0 - refresh key press is detected 1 - power button has been released before AP RO check was triggered 2 - trigger sequence timeout (refresh button not pressed in time) 3 - AP RO check triggered 4 - could not run the check, hash space not programmed 5 - could not run the check, hash space corrupted 6 - AP RO verification failed 7 - AP RO verification succeeded BUG=b:153764696 TEST=verified logging during various AP RO verification attempts: $ gsctool -a -L Log time zone is PST Dec 31 69 16:00:01 : 00 May 06 20 21:20:49 : 09 01 May 06 20 21:21:53 : 09 00 May 06 20 21:21:54 : 09 00 May 06 20 21:21:55 : 09 03 May 06 20 21:21:56 : 09 07 May 06 20 21:23:03 : 09 00 May 06 20 21:23:04 : 09 00 May 06 20 21:23:05 : 09 02 May 07 20 11:21:52 : 09 00 May 07 20 11:21:53 : 09 00 May 07 20 11:21:54 : 09 01 May 08 20 11:57:21 : 09 00 May 08 20 11:57:22 : 09 00 May 08 20 11:57:23 : 09 03 May 08 20 11:57:24 : 09 04 May 08 20 12:07:15 : 09 00 May 08 20 12:07:16 : 09 00 May 08 20 12:07:17 : 09 03 May 08 20 12:07:19 : 09 07 May 08 20 12:09:20 : 09 00 May 08 20 12:09:21 : 09 00 May 08 20 12:09:22 : 09 03 May 08 20 12:09:23 : 09 06 Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Change-Id: I739f9dbb2e7b8fc87601d61e1f87eb49d85bdf14 Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/ec/+/2191283 Reviewed-by: Mary Ruthven <mruthven@chromium.org> Reviewed-by: Namyoon Woo <namyoon@chromium.org>
