Looks like trunk@37090 has changed the logic that determines if router's button was pressed. This resulted in TEW632BRP always booting into failsafe mode because it detected pressed button (which was not pressed). Measure with voltmeter has shown that buttons on this router are actually active-low. This patch reflects this fact in board configuration and fixes 'load info failsafe mode' issue. Note: it looks like Trendnet TEW632BRP and a close relative to TEW-652BRP V1.0 and D-Link DIR-615C1, so same problem may exist on those routers as well. This patch doesn't affect routers other than 632BRP and unfortunately I do not have hardware to test this issue with other routers. This patch fixes #13893 and is tested on actuall Trendnet TEW632BRP. Signed-off-by: Nikolay Martynov <mar.kolya@gmail.com> Signed-off-by: Gabor Juhos <juhosg@openwrt.org> SVN-Revision: 37569
