2016-01-06commonlib: Prepare code to be included in cbfstool builds.Aaron Durbin
Some of the files need to be adjusted so that they can be used both in cbfstool as well as coreboot proper. For coreboot, add a <sys/types.h> file such that proper types can be included from both the tools and coreboot. The other chanes are to accomodate stricter checking in cbfstool. BUG=chrome-os-partner:48412 BUG=chromium:445938 BRANCH=None TEST=Built on glados including tools. Booted.

2016-01-06commonlib: Add function to compute relative offsets from two region_devices.Aaron Durbin
Provide a helper function which returns the relative offset between 2 region_devices that have a parent-child child relationship.

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.

2015-10-29commonlib/region: add xlate_region_deviceAaron Durbin
There are cases where one region_device needs to be accessed using offset/sizes from one address space that need the offset translated into a different address space for operations to take place. The xlate_region_device provides an offset that is subtracted from the incoming transaction before deferring to the backing access region.

2015-09-22coreboot: introduce commonlibAaron Durbin
Instead of reaching into src/include and re-writing code allow for cleaner code sharing within coreboot and its utilities. The additional thing needed at this point is for the utilities to provide a printk() declaration within a <console/console.h> file. That way code which uses printk() can than be mapped properly to verbosity of utility parameters.
