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>

2015-04-22rockchip/rk3288: Fix SPI clock divisor calculationJulius Werner
The code to calculate the RK3288 SPI controller's internal clock divisor is wrong: it assumes that the divisor register was an "n-1" divisor when it actually isn't (due to some misleading kernel code that was copied in here). This means that all SPI clocks are currently running lower than expected. This patch fixes the calculation and changes all callers such that the effective speeds stay the same. BRANCH=veyron BUG=chrome-os-partner:38352 TEST=Booted Jerry with and without the patch, dumping the divisor for flash and EC clocks. Made sure it stays the same.

2015-04-15veyron_*: Use common CBFS wrapperDavid Hendricks
This switches all the rk3288 platforms to use the common CBFS wrapper instead of implementing its own CBFS media driver. It also happens that veyron_* platforms use Gigadevice SPI flash (at least for now). As we use more SPI-related stuff, for example eventlog and vboot data in Brain's case, we will need to use more of the SPI API anyway. This prevents us from having to duplicate pieces of it for rk3288.

2015-04-08rk3288: Change all SoC headers to <soc/headername.h> systemJulius Werner
This patch is the start of a series to change all non-x86 SoC-specific headers to be included as <soc/header.h> instead of the old <soc/vendor/chip/header.h> or "header.h". It will add an include/soc/ directory under every src/soc/vendor/chip/ and append the .../include/ part of that to the global include path. This matches the usage of <arch/header.h> for architecture-specific headers and had already been done for some headers on Tegra. It has the advantage that a source file which does not know the specific SoC used (e.g. Tegra files common for multiple chips, or a global include file) can still include SoC-specific headers and access macros/types defined there. It also makes the includes for mainboard files more readable, and reduces the chance to pull in a wrong header when copying mainboard sources to use a different-related SoC (e.g. using a Tegra124 mainboard as template for a Tegra132 one). For easier maintainability, every SoC family is modified individually. This patch starts out by changing Rk3288. Also alphabetized headers in affected files since we touch them anyway. BUG=None TEST=Whole series: compared binary images for Daisy, Nyan_Blaze, Rush_Ryu, Storm, Urara and Veyron_Pinky. Confirmed that they are byte-for-byte identical except for timestamps, hashes, and __LINE__ macro replacements. Compile-tested individual patches.

2015-04-08rk3288: Re-write spi_xfer() to support full duplexDavid Hendricks
This change re-writes the spi_xfer() function to support full-duplex transfers. Even though the code looks much different, the same basic algorithm for setting up the transfer is used. The main difference is that reads from rxdr and writes to txdr occur simultaneously and accounting is more complicated, so I separated the higher-level accounting portion from the low-level FIFO handling portion to simplify things.
