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>

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.

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>

The default ME output is quite verbose and not all that useful unless you are actively debugging the ME and then you can enable the CONFIG_DEBUG_INTEL_ME option. This commit silences the firmware capabilities and the MBP output.

2013-12-21lynxpoint: me: Allow for more than MKHI MEI messagesDuncan Laurie
The original ME code was assuming that the only type of messages it would send were MKHI type and so it had some embedded checks for that header and that type of message. In order to support ICC messages this needs to change to handle different header types, so now the header will be sent first and then the data will follow, rather than the two both being sent in the same low-level function. This change has no real affect on the system, subsequent commit will add new ICC messages.

2013-12-21lynxpoint: Avoid any ME device communication in S3 pathDuncan Laurie
The management engine is occasionally hanging the system on resume when it is accessed. Since we actually don't need to do anything with it on resume it can be disabled early in the resume path and avoid assigning resources just to remove them later. suspend/resume on falco and check /sys/firmware/log to ensure that device 00:16.0 is disabled early and that no resources are probed or assigned and that the device init path does not execute.

2013-12-21lynxpoint me: add support for mbp clear wait in finalize stepDuncan Laurie
The management engine is slow, requiring at least 500ms between when the Dram Init Done message is sent (right after memory training) to when the MBP will report that it is successfully cleared and that the ME can finally be sent the EOP message. Currently this is adding 100-150ms to the boot time. If we defer waiting for the MBP Clear indicator until the finalize step we can gain back that lost time. boot on falco with SMI debugging enabled to ensure that the ME is locked down in the finalize step: Finalizing Coreboot SMI# #0 SMI_STS: PM1 APM ME: MBP cleared ME: mkhi_end_of_post ME: END OF POST message successful (0) Change-Id: Icab4c8c8e00eea67bed5e8154d91a1eb48a492d1 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/62633 Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: http://review.coreboot.org/4375 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi <patrick@georgi-clan.de>

2013-03-22x86: Unify arch/io.h and arch/romcc_io.hStefan Reinauer
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.
