2017-06-13device/pnp: remove struct io_infoSamuel Holland
The 'set' field was not used anywhere. Replace the struct with a simple integer representing the mask. initializer updates performed with: sed -i -r 's/\{ ?0(x([[:digit:]abcdefABCDEF]{3,4}))?, (0x)?[04]? ?\}/0\1/g' \ src/ec/*/*/ec.c sed -i -r 's/\{ ?0(x([[:digit:]abcdefABCDEF]{3,4}))?, (0x)?[04] ?\}/0\1/g' \ src/ec/*/*/ec_lpc.c \ src/superio/*/*/superio.c \ src/superio/smsc/fdc37n972/fdc37n972.c \ src/superio/smsc/sio10n268/sio10n268.c \ src/superio/via/vt1211/vt1211.c src/ec/kontron/it8516e/ec.c was manually updated. The previous value for IT8516E_LDN_SWUC appears to have been a typo, as it was out of range and had a zero bit in the middle of the mask.

2016-04-13superio/smsc/mec1308: Fix AddressMax value for SMBX mailboxMartin Roth
The way this was implemented before was causing ACPI failures. There was also a basic misunderstanding of what the AddressMax field was used for. In this case, because it's a fixed address, it should be the same as the AddressMin field. Getting rid of the addition in the field solves the ACPI output problem.

2016-02-01drivers/pc80: Add PS/2 mouse presence detectTimothy Pearson
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.

2015-11-24superio/smsc/mec1308: Fix IASL warningsMartin Roth
The SIO device needs to provide an _ADR object with the IO address as well as the address in the OperationRegion. ACPI provides two different Resource Descriptor Macros to describe the I/O areas required for a device. The FixedIO macro is only valid for 10-bit IO addresses. Use the IO macro instead. Thank you to recent IASL that allows for addition in the ASL file. :) Fixes these warnings: dsdt.aml 2276: Device (SIO) { Warning 3141 - ^ Missing dependency (Device object requires a _HID or _ADR in same scope) dsdt.aml 2390: FixedIO (0xa00, 0x34) Warning 3060 - ^ Maximum 10-bit ISA address (0x3FF) dsdt.aml 2394: FixedIO (0xa00, 0x34) Warning 3060 - ^ Maximum 10-bit ISA address (0x3FF) Lumpy now compiles its ASL tables with no warnings.

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>

Find all the (ramstage) implementations of enter()/exit() functions for the configuration state, register and call them through the new struct pnp_mode_ops.

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.
