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>
2015-04-22broadcom/cygnus: Implement I2C driverAnatol Pomazau
BUG=chrome-os-partner:35810 BRANCH=purin TEST=Enable I2C1, reset devboard codec, read a register. Here is the code that demonstrates how I2C works: i2c_init(1, 100*KHz); mdelay(50); int rc = i2c_writeb(1, 0x18, 1, 0x80); // reset codec printk(BIOS_INFO, "I2C reset rc=%d\n", rc); mdelay(50); uint8_t data = 0; rc = i2c_readb(1, 0x18, 43, &data); printk(BIOS_INFO, "I2C read rc=%d data=%x\n", rc, data); // data == 0x80 Change-Id: I0d202f8b0375b5ccd9f71b23fb0cadd5a70ae779 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: 6bbe9afe3dccd104f39c2c286d3765a28ea20141 Original-Signed-off-by: Anatol Pomazau <anatol@google.com> Original-Reviewed-on: https://chrome-internal-review.googlesource.com/195706 Original-Reviewed-by: Daisuke Nojiri <dnojiri@google.com> Original-Reviewed-by: Anatol Pomazau <anatol@google.com> Original-Commit-Queue: Anatol Pomazau <anatol@google.com> Original-Tested-by: Anatol Pomazau <anatol@google.com> Original-Change-Id: I178acef9de18fa854983294edcd2c05886795e2a Original-Reviewed-on: https://chromium-review.googlesource.com/263496 Original-Commit-Queue: Daisuke Nojiri <dnojiri@chromium.org> Original-Trybot-Ready: Daisuke Nojiri <dnojiri@chromium.org> Original-Tested-by: Daisuke Nojiri <dnojiri@chromium.org> Original-Reviewed-by: Daisuke Nojiri <dnojiri@chromium.org> Reviewed-on: http://review.coreboot.org/9908 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
