BUG=chrome-os-partner:11171 TEST=manual 1. Clear some of the writable-bits in the flash registers > ww 0x400fe40c 0xffff1234 write 0x400fe40c = 0xffff1234 > rw 0x400fe40c read 0x400fe40c = 0xffff1234 2. Reset using power+refresh 3. Register should be clear again > rw 0x400fe40c read 0x400fe40c = 0xffffffff 4. Sysinfo should indicate reset-pin reason AND hard-reset reason > sysinfo Reset flags: 0x0000000a (reset-pin power-on) 5. Reset using power+refresh 6. Sysinfo should indicate reset-pin reason only > sysinfo Reset flags: 0x00000002 (reset-pin) 7. Clear writable-bits again > ww 0x400fe40c 0xffff1234 write 0x400fe40c = 0xffff1234 8. Jump to another image. This should NOT trigger a hard reset. > sysjump A > sysinfo Reset flags: 0x00000402 (reset-pin sysjump) Change-Id: Ie1d6af2acc68217bb82faae464798ee85d63d1ea Signed-off-by: Randall Spangler <rspangler@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/27540 Reviewed-by: Bill Richardson <wfrichar@chromium.org>
