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 operator precedence error in LPDDR initJulius Werner
Upstream coreboot regularly runs Coverity over the code base. Turns out that's a good idea since it's really easy to screw yourself over with a missing parenthesis and some unfortunately deceptive line breaking. This patch fixes a bug in LPDDR3 initialization due to an incorrect operator precedence assumption ( ?: does not bind stronger than | ). In effect, instead of setting MR11[1:0] to 0b11 or 0b00 based on ODT, we're unconditionally setting MR0[1:0] to 0b11. Thankfully, MR0[1:0] seems to contain read-only bits so this might have not been a problem when ODT is off (which is currently true for all LPDDR boards). Also adding a redundant LPDDR_OP() around the 0 to make the intent clearer and changing 3 and 0 to 0x3 and 0x0 to make it more obvious that these are bit masks (right?).

2015-04-15rk3288: Fix failing DDR3 reboot testjinkun.hong
We want a reset signal to last 200us. The length of a reset signal is represented by BIT0~BIT16 in DDR_PUBL_PTR2. When DDR memory runs at 667MHz, the calculated value for the reset signal is 0x20850, which is bigger than the maximum value that can be described with 17 bits (0x1ffff). As a result, the memory controller only sees 0x850, which generates a 3.5us reset cycle instead, which violates the standard and negatively impacts memory stability. So instead, we now set it to the maximum value (0x1ffff) to prevent this overflow, resulting in a reset signal of 196us for 667MHz DDR memory.

2015-04-13rk3288: Increase the delay after DDR reset de-assert to 10us.Dailunxue
After DDR PHY reset de-asserted, DLL automatically starts to lock, and the lock time is maximum 5.12us. The output clock of DLL supplies the clocks of DDR controller and PHY digital logic. So before DLL lock, the clocks of DDR controller and PHY digital logic are indeterminate. When programming DDR in the period of DLL unlock, the programming maybe unstable because of the indeterminate clocks. So we need wait for at least 5.12us after de-asserting reset, then start to program DDR registers. 10us provide some safety margin.

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.
