2024-04-13superio/ite: Add special fan vectorsJoel Linn
A number of ITE SIOs support "special fan control vectors", which effectively allow non-linear fan speed control. This is for example used by the vendor firmware of the "HP Pro 3500 Series". The special vector registers won't be written to until the mb's devicetree configures `FAN_VECX.tmp_start != 0`.

2024-04-13superio/ite: Unify it8772f with common codeJoel Linn
The it8772f is now configured by the much better common code that is used for other chips in the family as well. This mainly concerns the EC, the GPIO functionality was not moved to common as it currently lacks a sane abstraction in any codebase. The datasheets of the it8772e(f) and it8728f (for reference) were studied and verified against the common code, adding exceptions where needed.

2024-01-31include/device/device.h: Remove CHIP_NAME() macroNicholas Sudsgaard
Macros can be confusing on their own; hiding commas make things worse. This can sometimes be downright misleading. A "good" example would be the code in soc/intel/xeon_sp/spr/chip.c: CHIP_NAME("Intel SapphireRapids-SP").enable_dev = chip_enable_dev, This appears as CHIP_NAME() being some struct when in fact these are defining 2 separate members of the same struct. It was decided to remove this macro altogether, as it does not do anything special and incurs a maintenance burden.

The .inc suffix is confusing to various tools as it's not specific to Makefiles. This means that editors don't recognize the files, and don't open them with highlighting and any other specific editor functionality. This issue is also seen in the release notes generation script where Makefiles get renamed before running cloc.

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>

2014-10-27superio: Use 'pnp_devfn_t' over 'device_t' in romstage componentEdward O'Callaghan
The romstage component of Super I/O support is in fact written around passing a lower and upper half packed integer. We currently have two typedef's for this, 'device_t' and 'pnp_devfn_t'. We wish to make use of 'pnp_devfn_t' over 'device_t' as 'device_t' changes it's typedef in the ramstage context and so is really a conflicting definition. This helps solve problems down the road to having the 'real' 'device_t' definition usable in romstage later.

2013-06-17pnp: Register implementations of enter/exit config stateNico Huber
Find all the (ramstage) implementations of enter()/exit() functions for the configuration state, register and call them through the new struct pnp_mode_ops. As our standard PnP functions are aware of the pnp_mode_ops, it's not necessary to call enter()/exit() around them anymore. Patch generated with the cocci below. It's not perfect. The movement of the enter()/exit() calls is somehow fragile. So I checked the remaining calls for sense, and changed some empty lines.

2013-06-17pnp: Provide alternative pnp_enable() implementationNico Huber
The current default implementation of pnp_enable() only disables devices - if set so in the devicetree - but does not enable them. Enablement takes place in pnp_enable_resources(). Yet, many PnP chips implement their own version of pnp_enable() which also enables devices if set in the devicetree. It's arguable, if enabling those devices makes sense, before they get resources assigned. Maybe we can't write the resource registers if not, who knows? The least we can do is providing a common implementation for this behavior, and get rid of some code duplication. Used the following cocci: @@ expression e; @@ +pnp_alt_enable(e); -pnp_set_logical_device(e); ( -pnp_set_enable(e, !!e->enabled); | -(e->enabled) ? pnp_set_enable(e, 1) : pnp_set_enable(e, 0); | -if (e->enabled) { pnp_set_enable(e, 1); } -else { pnp_set_enable(e, 0); } ) Change-Id: I8d695e8fcd3cf8b847b1aa99326b51a554700bc4 Signed-off-by: Nico Huber <nico.h@gmx.de> Reviewed-on: http://review.coreboot.org/3480 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Ronald G.

Here's the great news: From now on you don't have to worry about hitting the right io.h include anymore. Just forget about romcc_io.h and use io.h instead. This cleanup has a number of advantages, like you don't have to guard device/ includes for SMM and pre RAM anymore. This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable. Potentially in the future some of the code in the io.h __PRE_RAM__ path should move to device.h or other device/ includes instead, but that's another incremental change.
