2020-03-17src (minus soc and mainboard): Remove copyright noticesPatrick Georgi
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.

2019-11-18sb/intel/bd82x6x: Handle enabling of GbENico Huber
The integrated GbE port is toggled via the Backed-Up Control (BUC) register. We already disable it according to the devicetree setting but never enabled it. This could lead to the confusing situation that it was disabled before (different build, vendor BIOS, etc.) but shouldn't be anymore. As we need a full reset after enabling GbE, do it in early PCH init.

This also changes the name to mainboard_pch_lpc_setup to better reflect that it is an optional mainboard hook. This adds an empty weakly linked default. The rationale behind this change is that without an implementation of the hook some features might not work but that the result is likely still able to boot, so it can be made optional.

2015-10-03sandybridge ivybridge: Treat native init as first class citizenAlexandru Gagniuc
This is a sad story. We have three different code paths for sandybridge and ivybridge: proper native path, google MRC path, and, everyone's favorite: Intel FSP path. For the purpose of this patch, the FSP path lives in its own little world, and doesn't concern us. Since MRC was first, when native files and variables were added, they were suffixed with "_native" to separate them from the existing code. This can cause confusion, as the suffix might make the native files seem parasitical. This has been bothering me for many months. MRC should be the parasitical path, especially since we fully support native init, and it works more reliably, on a wider range of hardware. There have been a few board ports that never made it to coreboot.org because MRC would hang. gigabyte/ga-b75m-d3h is a prime example: it did not work with MRC, so the effort was abandoned at first. Once the native path became available, the effort was restarted and the board is now supported. In honor of the hackers and pioneers who made the native code possible, rename things so that their effort is the first class citizen.

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>
