2021-05-06src: Retype option API to use unsigned integersAngel Pons
The CMOS option system does not support negative integers. Thus, retype and rename the option API functions to reflect this.

2021-04-29ec/lenovo/h8/h8.c: Skip setting volume if out of rangeAngel Pons
This change is needed to update the option API to use unsigned integers. The CMOS option system does not support negative numbers. The volume field is only 8 bits long. Do not set the volume if it is out of range. Also, use an out-of-range value as fallback to skip setting the volume when it cannot be read using the option API, to preserve the current behavior.

2020-05-26ec/lenovo/h8: Config the ec hardware ids for newer thinkpadsDa Lao
Currently coreboot is using the ec hardware id IBM0068 for all thinkpads, but for newer thinkpads the id maybe LEN0068 or LEN0268. On Windows, the Lenovo Vantage app can't get battery details when using IBM0068. This patch config this id by motherboard. The hardware IDs for the following models can be found by searching for disassembled dsdt.asl on vendor BIOS: (But this info is not easy to find online. So I only changed some of the thinkpads.)

2020-05-13ec/lenovo/h8: Reintroduce h8_mb_init() for specific boardsBill XIE
Mainboard specific dock-init mechanism introduced https://review.coreboot.org/c/coreboot/+/36093 works on most boards, but https://ticket.coreboot.org/issues/256 shows that some boards (e.g. x201 and t410) need communication with h8 EC to enable or disable dock, (in dock_connect() and dock_disconnect() respectively) so they must be done after the h8 EC is brought up, which is not garanteed in the above mainboard specific dock-init mechanism. This time, a hook function h8_mb_init() will be called at the end of h8_enable(). (in place of the ancient h8_mainboard_init_dock() removed in CB:36093) Its default implementation is a weak empty function, but could be overrided with a strong one for boards needing to perform actions which should be done after h8 EC is brought up. This should fix the regression detected in https://ticket.coreboot.org/issues/256 Change-Id: I3674fbfeab2ea2cd2a4453a8e77521157d553388 Signed-off-by: Bill XIE <persmule@hardenedlinux.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/39708 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Patrick Rudolph <siro@das-labor.org>

This change moves all ACPI table support in coreboot currently living under arch/x86 into common code to make it architecture independent. ACPI table generation is not really tied to any architecture and hence it makes sense to move this to its own directory. In order to make it easier to review, this change is being split into multiple CLs. This is change 3/5 which basically is generated by running the following command: $ git grep -iIl "arch/acpi" | xargs sed -i 's/arch\/acpi/acpi\/acpi/g' BUG=b:155428745 Change-Id: I16b1c45d954d6440fb9db1d3710063a47b582eae Signed-off-by: Furquan Shaikh <furquan@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/40938 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: HAOUAS Elyes <ehaouas@noos.fr>

They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

There are two known reverse-engineered ways to manage battery thresholds. This patch implements them and adds a way to enable them for different mainboards. Tested on W530 with 4.18.3-gentoo kernel and X220 with 4.20.11. Works fine with new Linux userspace API for controlling battery thresholds, available since 4.17. (/sys/class/power_supply/BAT0/charge_(start|stop)_threshold). The new API is supported by TLP (you might need to set NATACPI_ENABLE=1 in /etc/tlp.conf). tpacpi-bat works fine too.

On my Thinkpad T420 the default 3000ms SeaBIOS timeout is too short, it takes nearly 5000ms for my keyboard to become ready. Timing out before it's ready leads to pretty bad behavior: I cannot use my keyboard at all to control SeaBIOS, nor the subsequent GRUB instance. Linux is fine though, possibly because it does its own keyboard init.

2017-02-24ec/lenovo/h8: Guard against EC bugs in the battery status logic.Tobias Diedrich
On my Thinkpad with an H8-compatible ENE KB9012 EC (GDHT92WW 1.52), when the battery is nearly full and we switch from battery to AC by plugging in the cable, the current rate will not drop to 0 immediately, but the discharging state is cleared immediately. This leads to the code trying to process an invalid rate value >0x8000, leading to a displayed rate of >1000W. This patch changes the logic to deal with these corner cases.

2016-11-18ec/lenovo/h8: Add USB Always OnNicola Corna
USB AO is the internal name for the dedicated charging port on ThinkPads when in S3 or lower. AOEN (bit 0) is internal name for enabling this feature while AOCF (bits 2 and 3) is the configuration field. According to Peter Stuge, AOCF can be configured in this way: 00 => AC S3 S4 S4 USB on, battery S3 USB on, battery S4 S5 off 11 => AC S3 S4 S4 USB on, battery S3 S4 S5 USB off 10, 01 => equivalent to 00 This commit also adds a new configuration field in the CMOS of the X220 and the X201 to activate this feature. It probably can be also added to all the ThinkPads that support this functionality. With this functionality USB devices are able to negotiate full power from the dedicated port (usually the yellow one) even in S3. Tested on a X201 and X220 with an Android smartphone: with this feature enabled it shows "Charging" when connected during S3, without it it shows "Charging slowly" (or it doesn't charge at all on the X201). For some reasons the "AC only" mode doesn't work, so it has been disabled.

On certain Winbond SuperIO devices, when a PS/2 mouse is not present on the auxiliary channel both channels will cease to function if the auxiliary channel is probed while the primary channel is active. Therefore, knowledge of mouse presence must be gathered by coreboot during early boot, and used to enable or disable the auxiliary PS/2 port before control is passed to the operating system. Add auxiliary channel PS/2 device presence detect, and update the Winbond W83667HG-A driver to flag the auxiliary channel as disabled if no device was detected.

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>

This change switches all ECs and the generic EC ACPI code to be autoincluded by Makefile.inc, rather than having to be mentioned explicitly in ec/Makefile.inc or in ec/<vendor>/Makefile.inc. This means, vendor and ec directories are now "drop in", e.g. be placed in the coreboot directory hierarchy without having to modify any higher level coreboot files. The long term plan is to enable out of tree components to be built with a given coreboot version (given that the API did not change).
