2015-10-31tree: drop last paragraph of GPL copyright headerPatrick Georgi
It encourages users from writing to the FSF without giving an address. Linux also prefers to drop that and their checkpatch.pl (that we imported) looks out for that. This is the result of util/scripts/no-fsf-addresses.sh with no further editing.

2015-10-27include/timer.h: Guard `timer_monotonic_get()` calls by ↵Paul Menzel
`CONFIG_HAVE_MONOTONIC_TIMER` Some platforms do not have `timer_monotonic_get()` implemented. So only call `timer_monotonic_get()` if `CONFIG_HAVE_MONOTONIC_TIMER` is selected and set the times to 0 otherwise.

2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>

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.

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.
