| 2015-10-31 | tree: drop last paragraph of GPL copyright header | Patrick 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.

| 2015-07-29 | arm, arm64, mips: Add rough static stack size checks with -Wstack-usage | Julius Werner | |
| We've seen an increasing need to reduce stack sizes more and more for space reasons, and it's always guesswork because no one has a good idea how little is too litte. We now have boards with 3K and 2K stacks, and old pieces of common code often allocate large temporary buffers that would lead to very dangerous and hard to detect bugs when someone eventually tries to use them on one of those. This patch tries improve this situation at least a bit by declaring 2K as the minimum stack size all of coreboot code should work with. It checks all function frames with -Wstack-usage=1536 to make sure we don't allocate more than 1.5K in a single buffer. This is of course not a perfect test, but it should catch the most common situation of declaring a single, large buffer in some close-to-leaf function (with the assumption that 0.5K is hopefully enough for all the "normal" functions above that). Change one example where we were a bit overzealous and put a 1K buffer into BSS back to stack allocation, since it actually conforms to this new assumption and frees up another kilobyte of that highly sought-after verstage space. Not touching x86 with any of this since it's lack of __PRE_RAM__ BSS often requires it to allocate way more on the stack than would usually be considered sane. BRANCH=veyron BUG=None TEST=Compiled Cosmos, Daisy, Falco, Blaze, Pit, Storm, Urara and Pinky, made sure they still build as well as before and don't show any stack usage warnings.

| 2015-05-21 | Remove address from GPLv2 headers | Patrick 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> | |||
| 2015-04-17 | Add delay before reading GPIOs in gpio_base2_value() | David Hendricks | |
| This adds a 10us delay in between (re-)configuring and reading GPIOs in gpio_base2_value() to give the values stored some time to update. As far as I know this hasn't bitten us since the function was added, but adding a short delay here seems like the right thing to do.

| 2015-04-10 | gpio: cosmetic changes to tristate_gpios.c | David Hendricks | |
| This patch makes a few cosmetic changes: - Rename tristate_gpios.c to gpio.c since it will soon be used for binary GPIOs as well. - Rename gpio_get_tristates() to gpio_base3_value() - The binary version will be called gpio_base2_value(). - Updates call sites. - Change the variable name "id" to something more generic.
