2015-12-29device/pnp: Ability to set vendor specific logical device configDamien Zammit
According to the PNP ISA v1.0a spec, config registers in the range of 0xf0 up to 0xfe are vendor defined and may be used for any purpose. Config register 0xff is reserved and is defined as such. Currently, only vendor specific registers 0xf0, 0xf1, 0xf4, and 0xfa are able to be set using the PNP_MSCx bit flag masks. This patch adds support for all 15 vendor specific config registers, and updates the existing superio pnp_info to use them where appropriate.

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>

2013-06-17pnp: Implement common handling for PnP config modesNico Huber
Many super i/o chips only answer to PnP requests if they are in a configuration state (sometimes also called ext func mode). To cope with that, the code of many chips implements its own version of our default PnP functions like pnp_set_resource(), pnp_enable_resource() etc. To avoid this code duplication, this patch extends our PnP device interface with optional functions to enter and exit configuration mode.

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.
