2022-12-07mb,sb,soc/intel: Drop useless IO trap handlersKyösti Mälkki
There are four requirements for the SMI to hit a printk() this commit now removes. Build must have DEBUG_SMI=y, otherwise any printk() is a no-op inside SMM. ASL must have a TRAP() with argument 0x99 or 0x32 for SMIF value. Platform needs to have IO Trap #3 enabled at IO 0x800. The SMI monitor must call io_trap_handler for IO Trap #3. At the moment, only getac/p470 would meet the above criteria with TRAP(0x32) in its DSDT _INI method. The ASL ignores any return value of TRAP() calls made. A mainboard IO trap handler should have precedence over a southbridge IO trap handler. At the moment we seem to have no cases of the latter to support, so remove the latter.

Having some symmetry with <soc/nvs.h> now allows to reduce the amount of gluelogic to determine the size and cbmc field of struct global_nvs. Since GNVS creation is now controlled by ACPI_SOC_NVS, drivers/amd/agesa/nvs.c becomes obsolete and soc/amd/cezanne cannot have this selected until <soc/nvs.h> exists.

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.

Use the common Intel code to set up smm and the smihandler. This is expected to break S3 resume and other smihandler related functionality as this code is meant to be used with CONFIG_SMM_TSEG. Platforms (i945, pineview, x4x) using this southbridge will adapt the CONFIG_SMM_TSEG codepath in subsequent patches. Tested on Intel D945GCLF, still boots fine but breaks S3 resume support because it hangs on SMI.

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>

2013-03-22x86: 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.

2011-06-29i82801gx: read RTC status register to prevent IRQ stormSven Schnelle
My Thinkpad appeared dead. After investigation, it turned out that the RTC Alarm was triggering an RTC PM1 SMI, but the SMI handler didn't read the status register, so it was triggered again. This is a really nasty situation, as it means you have to dissemble your Notebook just to unplug the RTC battery.

2010-12-08first round name simplification. drop the <component>_ prefix.stepan
the prefix was introduced in the early v2 tree many years ago because our old build system "newconfig" could not handle two files with the same name in different paths like /path/to/usb.c and /another/path/to/usb.c correctly. Only one of the files would end up being compiled into the final image. Since Kconfig (actually since shortly before we switched to Kconfig) we don't suffer from that problem anymore. So we could drop the sb700_ prefix from all those filenames (or, the <componentname>_ prefix in general) - makes it easier to fork off a new chipset - makes it easier to diff against other chipsets - storing redundant information in filenames seems wrong Signed-off-by: <stepan@coresystems.de> Acked-by: Patrick Georgi <patrick@georgi-clan.de> Acked-by: Peter Stuge <peter@stuge.se> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@6149 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
