2016-12-05spi: Define and use spi_ctrlr structureFurquan Shaikh
1. Define a new structure spi_ctrlr that allows platforms to define callbacks for spi operations (claim bus, release bus, transfer). 2. Add a new member (pointer to spi_ctrlr structure) in spi_slave structure which will be initialized by call to spi_setup_slave. 3. Define spi_claim_bus, spi_release_bus and spi_xfer in spi-generic.c which will make appropriate calls to ctrlr functions.

2016-12-05spi: Pass pointer to spi_slave structure in spi_setup_slaveFurquan Shaikh
For spi_setup_slave, instead of making the platform driver return a pointer to spi_slave structure, pass in a structure pointer that can be filled in by the driver as required. This removes the need for platform drivers to maintain a slave structure in data/CAR section.

2016-12-05spi: Fix parameter types for spi functionsFurquan Shaikh
1. Use size_t instead of unsigned int for bytes_out and bytes_in. 2. Use const attribute for spi_slave structure passed into xfer, claim bus and release bus functions.

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>
