Now both copies of the event state live in host_event_commands.c, and lpc / memmap just shadows the main copy. BUG=chrome-os-partner:11172 TEST=manual Boot system. should see events 0x2000, 0x80, 0x08 get set and then cleared. At U-boot prompt, type on keyboard. Should set event 0x1000 get set, but only on the first keypress (because U-boot doesn't consume that event). Then from EC console, hostevent clear 0x1000 -> see event 0x1000 clear hostevent clear 0x1000 -> no debug output (it's already clear) hostevent clearb 0x1000 -> see event copy B 0x1000 clear hostevent clearb 0x1000 -> no debug output (copy B is already clear) Change-Id: I855c035865649ba1490cd9027157d5bcdcc9895f Signed-off-by: Randall Spangler <rspangler@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/27321
