They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2016-10-11nb/gm45/gma.c: use linux code to compute LVDS dotclock divisorsArthur Heymans
This reuses linux code (at least 4.1) to compute the graphic clock divisors for LVDS displays on the gm45 northbridge. The divisors m1, m2, n, p1, p2 need to be such that "BASE_FREQUECY * (5 * (m1 + 2) + (m2 + 2)) / (n + 2) / (p1 * p2)" is as close as possible to the target_frequency. On g4x hardware the BASE_FREQUENCY is 96000kHz. This potentially increases LVDS display compatibility.

The intel x4x and gm45 have very similar integrated graphic devices. Currently the x4x native graphic init enables VGA, while gm45 can output on LVDS. This patch reuses the x4x graphic initialisation code to enable output on VGA in gm45 in a way that the behavior is similar to vbios: If no VGA display is connected the internal LVDS screen is used. If an external screen is detected on the VGA port it will be used instead.

2016-09-07gm45/gma.c: clean up some registersArthur Heymans
According to "G45: Volume 3: Display Register Intel ® 965G Express Chipset Family and Intel ® G35 Express Chipset Graphics Controller" some registries are set incorrectly in gm45/gma.c. Some values are changed after comparing them with the values the i915 linux kernel (3.13 was used) module sets while modesetting. The values were obtained using 'intel_reg' from intel-gpu-tools, during a normal boot and with 'nomodeset' as a kernel argument. Some registers that don't exist on gm45 are set in gma.c, which is probably the result of copying code from a more recent intel northbridge. The result is that that gm45 laptops with wxga displays still work as before. gm45 laptops with wxga+ or higher resolution now just work, where previously a black screen was shown. TEST: build with native graphic init and flash on a gm45 target, like lenovo x200.

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>
