Fix reports found by undefined behavior sanitizer. Left shifting an int where the right operand is >= the width of the type is undefined. Add UL suffix since it's safe for unsigned types.

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.

2015-05-21Remove 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>

2014-07-11intel/lynxpoint: Work around XHCI resume issuesDuncan Laurie
When USB3 devices are attached while in suspend, or two USB3 devices that are both plugged in are switched to the other port while in suspend the kernel does not seem to notice this -- despite the cold attach status bit. This results in the devices showing up in the USB list at the old enumerated device numbers and higher layers continuing to think they are present but not reseponding. With the kernel workaround to deal with devices that are logically disconnected it is possible for firmware to send a warm port reset to devices that are in this state and then the kernel will see them disappear and handle it properly. This same issue exists in the EFI firmware on the Whitetip Mountain 2 reference board so it is not specifically a coreboot bug. If this behavior is fixed in the kernel then this workaround could be removed since it is in RW firmware.

2014-07-11intel/lynxpoint: xhci: Revert suspend/resume changesDuncan Laurie
I have been attempting to work around USB3 issues that appear in the kernel with hacks in the firmware, but this is resulting in more headaches in the kernel. Instead remove all the work that was being done at resume time and undo the change that was issuing a warm reset to all ports at suspend time. The bad device behavior will be dealt with at the kernel level to handle devices that get stuck in polling state after enable/disable sequence.

Some USB3 devices are not showing up after suspend/resume cycles. In particular if a device uses a lower power state like U2 it may take longer to come up and the firmware needs to wait after sending a warm port reset. In addition skipping port reset to connected ports in the way into suspend was causing problems so instead send all ports a reset before suspend.

2013-12-21lynxpoint: Route all USB ports to XHCI in finalize stepDuncan Laurie
This commit adds a new Kconfig option for the LynxPoint southbridge that will have coreboot route all of the USB ports to the XHCI controller in the finalize step (i.e. after the bootloader) and disable the EHCI controller(s). Additionally when doing this the XHCI USB3 ports need to be put into an expected state on resume in order to make the kernel state machine happy. Part of this could also be done in depthcharge but there are also some resume-time steps required so it makes sense to keep it all together in coreboot. This can theoretically save ~100mW at runtime. Verify that the EHCI controller is not found in Linux and that booting from USB still works.
