2015-03-26timer: remove rela_time typeAaron Durbin
Current usage doesn't require rela_time. Remove it. BUG=None BRANCH=None TEST=Built and booted.

2015-03-21timer: add stopwatch constructAaron Durbin
There's a lot of places where expiration and running time are open coded. Allow for those places to be simplified by adding a stopwatch construct. The stopwatch can have an expiration or just be used to accumulate time. BUG=None TEST=Built and verified API works as expected by using implementation.

2014-07-31timer: Add functions to initialize absolute timer structures.Gabe Black
Otherwise there's no good way to create an absolute timer structure without fiddling with its internal structure or assuming a zero initialized structure has a value of zero.

2013-05-05timer.h: add mono_time_diff_microseconds()David Hendricks
The current way to get a simple mono_time difference is: 1. Declare a rela_time struct 2. Assign it the value of mono_time_diff(t1, t2) 3. Get microseconds from it using rela_time_in_microseconds(). This patch adds a simpler method. Now one only needs to call mono_time_diff_microseconds(t1, t2) to obtain the same value which is produced from the above three steps.

2013-05-01coreboot: add timer queue implementationAaron Durbin
A timer queue provides the mechanism for calling functions in the future by way of a callback. It utilizes the MONOTONIC_TIMER to track time through the boot. The implementation is a min-heap for keeping track of the next-to-expire callback.

2013-05-01coreboot: introduce monotonic timer APIAaron Durbin
The notion of a monotonic timer is introduced. Along with it are helper functions and other types for comparing times. This is just the framework where it is the responsibility of the chipset/board to provide the implementation of timer_monotonic_get(). The reason structs are used instead of native types is to allow for future changes to the data structure without chaning all the call sites.
