2017-09-14usbdebug: Fix init and add support for postcarKyösti Mälkki
It was originally designed such that if usbdebug_init() was called before cbmem_initialize(), it would fetch the already-initialized state from CBMEM. This changed when cbmem_find() behaviour changed to require cbmem_initialize() to be called first. As a result, ramstage had to reinitialize all of the EHCI controller and USB endpoints on entry. This was slow, specially with AMD hardware where one can scan USB ports to probe for the debug dongle. For postcar and ramstage, move usbdebug entry such that it is triggered from CBMEM_INIT_HOOK instead of console_init(). Side-effect of this is usbdebug console shows 'coreboot-xxx ... starting...' line only for romstage. Initialisation for usbdebug is never done in postcar. If you have USBDEBUG_IN_ROMSTAGE=n, postcar will not have console output on usb either. While at it, fix also some other __PRE_RAM__ cases to ENV_ROMSTAGE and alike.

2017-08-07usbdebug: Force EHCI to D0 stateKyösti Mälkki
When resuming from ACPI S3 suspend, EHCI controller may be in D3 power-management state. Bring it to D0 early so it is functional for console. NOTE: D3hot->D0 transition was observed to reset previous programming of PCI_COMMAND register.

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.

2015-05-21Remove 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>
