google/gale: Turn on monotonic timer support
Without monotonic timer support, timer related APIs like
timer_monotonic_get etc. are optimized out by the compiler. This
results in timed loops to become indefinite loops
stopwatch_init_msecs_expire(...);
do {
something();
} while (!stopwatch_expired(...));
In our specific case, loops sampling the recovery/wipeout button
in src/mainboard/google/gale/chromeos.c:get_switch_state() turned
into infinite loops and the boot didn't proceed.
BUG=chrome-os-partner:49249
TEST=Confirmed that the loop breaks per the specified timeout
using the minicom's console log time stamps
[2016-04-11 12:34:37] recovery button pressed
[2016-04-11 12:34:45] wipeout requested, checking recovery
[2016-04-11 12:34:53] recovery requested
BRANCH=none
