2017-08-06sb/intel/*: Use common SMBus functionsArthur Heymans
All Intel southbridges implement the same SMBus functions. This patch replaces all these similar and mostly identical implementations with a common file. This also makes i2c block read available to all those southbridges. If the northbridge has to read a lot of SPD bytes sequentially, using this function can reduce the time being spent to read SPD five-fold.

2017-06-13Consolidate reset API, add generic reset_prepare mechanismJulius Werner
There are many good reasons why we may want to run some sort of generic callback before we're executing a reset. Unfortunateley, that is really hard right now: code that wants to reset simply calls the hard_reset() function (or one of its ill-differentiated cousins) which is directly implemented by a myriad of different mainboards, northbridges, SoCs, etc. More recent x86 SoCs have tried to solve the problem in their own little corner of soc/intel/common, but it's really something that would benefit all of coreboot. This patch expands the concept onto all boards: hard_reset() and friends get implemented in a generic location where they can run hooks before calling the platform-specific implementation that is now called do_hard_reset(). The existing Intel reset_prepare() gets generalized as soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now easily be added later if necessary). We will also use this central point to ensure all platforms flush their cache before reset, which is generally useful for all cases where we're trying to persist information in RAM across reboots (like the new persistent CBMEM console does). Also remove cpu_reset() completely since it's not used anywhere and doesn't seem very useful compared to the others.

2015-04-27kbuild: automatically include southbridgesStefan Reinauer
This change switches all southbridge vendors and southbridges to be autoincluded by Makefile.inc, rather than having to be mentioned explicitly in southbridge/Makefile.inc or in southbridge/<vendor>/Makefile.inc. In order to be able to drop southbridge/amd/Makefile.inc, some scattered source files had to be moved to a southbridge/amd/common directory, in accordance to what we are doing on other architectures already. This means, vendor and southbridge directories are now "drop in", e.g. be placed in the coreboot directory hierarchy without having to modify any higher level coreboot files. The long term plan is to enable out of tree components to be built with a given coreboot version (given that the API did not change).

Because we had no stack on romcc boards, we had a separate, not as powerful clone of printk: print_*.

2014-10-22cmos: Rename the CMOS related functions.Gabe Black
Most of the code related to the mc146818 is not related to the RTC and is really for managing the CMOS storage. Since we intend to add a generic API for RTC drivers it's inconvenient for those functions to have an rtc_ prefix. This CL renames those functions so they start with cmos_ instead. There are some places where rtc_init was called with a comment that says something about starting the RTC. That wasn't correct before (the RTC is always running), but it looks a little odd now that the function is called cmos_init. This CL also opportunistically cleans up some style problems in this file.

2012-11-27Get rid of drivers classPatrick Georgi
The use of ramstage.a required the build system to handle some object files in a special way, which were put in the drivers class. These object files didn't provide any symbols that were used directly (but only via linker magic), and so the linker never considered them for inclusion. With ramstage.a gone, we can drop this special class, too.

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
