2019-10-22AUTHORS: Move src/drivers/[a*-i*] copyrights into AUTHORS fileMartin Roth
As discussed on the mailing list and voted upon, the coreboot project is going to move the majority of copyrights out of the headers and into an AUTHORS file. This will happen a bit at a time, as we'll be unifying license headers at the same time. Updated Authors file is in a separate commit.

2018-03-14drivers/intel/gma: fix opregion SCI register for Atom platformsMatt DeVillier
Most Intel platforms use separate registers for software-based SMI (0xe0) and SCI (0xe8), but Atom-based platforms use a single combined register (0xe0) for both. Adjust opregion implementation to use the correct register for Atom-based platforms.

2017-02-04drivers/intel/gma/vbt: Add Kconfig symbol for SSC refNico Huber
The selection of the SSC reference frequency for LVDS was based on a completely unrelated clock. The `ssc_freq` flag should be set when the SSC reference runs at a different frequency than the general display reference clock (DREF). For most platforms, there is no choice, i.e. for i945 and gm45 the SSC reference always differs from the display reference clock (i945: 66Mhz SSC vs. 48MHz DREF; gm45: 100MHz SSC vs. 96Mhz DREF), for Nehalem and newer, it's the same frequency for SSC/non-SSC (120MHz). The only, currently supported platform with a choice seems to be Pineview, where the alternative is 100MHz vs. the default 96MHz.

2016-11-29drivers/intel/gma: Hook up libgfxinitNico Huber
Add `libgfxinit` as another option for native graphics initialization. For that, the function gma_gfxinit() (see drivers/intel/gma/i915.h) has to be called by the respective northbridge/soc code. A mainboard port needs to select `CONFIG_MAINBOARD_HAS_LIBGFXINIT` and implement the Ada package `GMA.Mainboard` with a single function `ports` that returns a list of ports to be probed for displays. v2: Update 3rdparty/libgfxinit to its latest master commit to make things buildable within coreboot. v3: Another update to 3rdparty/libgfxinit. Including support to select the I2C port for VGA.

Old igd.asl had inconsistent addresses (between _DOD and actual device) and ghost devices. Any of those is enough to make brightness on windows fail and make igd.asl out-of-ACPI-spec. Also old code favoured ridiculous copying of the same thing 6 times per chipset. Leave only hooking up and chipset-specific part in chipset directory. Move NVS handling and ACPI-spec parts to a common file.

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>
