2020-05-02acpi: Move ACPI table support out of arch/x86 (3/5)Furquan Shaikh
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>

2020-03-18mainboard/[g-p]*: 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.

2016-08-27lenovo/x200,t400: enable C4 cpu low power stateArthur Heymans
This enables the C4 low power state on the lenovo x200 and t400. It's inspired by the thread on the mailinglist: "[coreboot] Lenovo X200 running Coreboot drains 3-4W more power than with Vendor BIOS". What this does, is to enable a C3 state using MWAIT(C3) request and set the southbridge config c4onc3_enable to automatically upgrade C3 to the lower power C4 state. The latency (0x37) is the same value used by the vendor bios. With C4 enabled the idle power consumption is about ~2-3W lower. TEST= build and install on target. Use powertop top to measure power usage. To manually disable c-state to compare them, do (tested on linux 4.4): echo 1 > /sys/devices/system/cpu/cpu*/cpuidle/stateX/disable Change-Id: I1a1663a7662ebc7157a965667680688ad6a33545 Signed-off-by: Arthur Heymans <arthur@aheymans.xyz> Reviewed-on: https://review.coreboot.org/15251 Tested-by: build bot (Jenkins) Reviewed-by: Swift Geek Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Nico Huber <nico.h@gmx.de>

2015-10-31tree: drop last paragraph of GPL copyright headerPatrick Georgi
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. This is the result of util/scripts/no-fsf-addresses.sh with no further editing.
