i.MX31 specific Configuration Options:
--------------------------------------
- Timer precision:
CONFIG_MX31_TIMER_HIGH_PRECISION
Enable higher precision timer. The low-precision timer
(default) provides approximately 4% error, whereas the
high-precision timer is about 0.4% accurate. The extra
accuracy is achieved at the cost of higher computational
overhead, which, in places where time is measured, should
not be critical, so, it should be safe to enable this
option.
