2021-11-04soc/intel: Replace bad uses of `find_resource`Angel Pons
The `find_resource` function will never return null (will die instead). In cases where the existing code already accounts for null pointers, it is better to use `probe_resource` instead, which returns a null pointer instead of dying.

2020-03-18soc: Remove copyright noticesPatrick Georgi
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.

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.

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>

2014-05-10baytrail: Add support for LPSS and SCC devices in ACPI modeDuncan Laurie
This adds the option to put LPSS and SCC devices into ACPI mode by saving their BAR0 and BAR1 base addresses in a new device NVS structure that is placed at offset 0x1000 within the global NVS table. The Chrome NVS strcture is padded out to 0xf00 bytes so there is a clean offset to work with as it will need to be used by depthcharge to know what addresses devices live at. A few ACPI Mode IRQs are fixed up, DMA1 and DMA2 are swapped and the EMMC 4.5 IRQ is changed to 44. New ACPI code is provided to instantiate the LPSS and SCC devices with the magic HID values from Intel so the kernel drivers can locate and use them. The default is still for devices to be in PCI mode so this does not have any real effect without it being enabled in the mainboard devicetree. Note: this needs the updated IASL compiler which is in the CQ now because it uses the FixedDMA() ACPI operator. BUG=chrome-os-partner:23505,chrome-os-partner:24380 CQ-DEPEND=CL:179459,CL:179364 BRANCH=none TEST=manual tests on rambi device: 1) build and boot with devices still in PCI mode and ensure that nothing is changed 2) enable lpss_acpi_mode and see I2C devices detected by the kernel in ACPI mode. Note that by itself this breaks trackpad probing so that will need to be implemented before it is enabled. 3) enable scc_acpi_mode and see EMMC and SDCard devices detected by the kernel in ACPI mode. Note that this breaks depthcharge use of the EMMC because it is not longer discoverable as a PCI device.
