2020-03-17src (minus soc and mainboard): 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.

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>

Because we had no stack on romcc boards, we had a separate, not as powerful clone of printk: print_*. Back in the day, like more than half a decade ago, we migrated a lot of boards to printk, but we never cleaned up the existing code to be consistent. instead, we worked around the problem with a very messy console.h (nowadays the mess is hidden in romstage_console.c and early_print.h) This patch cleans up the northbridge code to use printk() on all non-ROMCC boards.

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.

2010-09-20A number of cleanups for 440BX raminit code.Keith Hui
Resolves a number of TODOs items within, and clarified a number of other TODOs. Change register_values[] from long to u8 (byte). For what we are doing this is sufficient and makes it only 1/4 the size. Remove a hard-coding of SDRAMC register that is redundant and now incorrect, now that SDRAMC is conditioned on SDRAMPWR_4DIMM Kconfig and set through register_values[]. This fixes all boards with 3 DIMM slots (e.g. ASUS P2B, A-Trend ATC-6220). RPS registers are now set in runtime code; remove it from register_values[] table. Bring DUMPNORTH() back. The code it refers to is still there. Move #define of NB up so the DUMPNORTH() macro can use it.

2010-03-17From Keith Hui:Keith Hui
This patch implements a full SDRAM buffer strength programming algorithm in set_dram_buffer_strength(), checked against my P2B-LS factory BIOS. With this in place, I now have 133MHz (!) stability with three 256MB PC133 modules, and can boot Fedora 11 all the way to the init daemon (actually upstart, but that's another story). Not to login prompt yet. We'll find out why later. This again assumes a 4-DIMM board because that's all I have. I need someone with a 3-DIMM board to test it. As a bonus, there's a big comment block within that illustrates the algorithm. :-) Signed-off-by: Keith Hui <buurin@gmail.com> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5238 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1

2010-03-05This patch is from 2009-10-20Uwe Hermann
Convert all DEBUG_SMBUS, DEBUG_SMI, and DEBUG_RAM_SETUP custom and local #defines into globally configurable kconfig options (and Options.lb options for as long as newconfig still exists) which can be enabled by the user in the "Debugging" menu. The respective menu items only appear if a board is selected where the chipset code actually provides such additional DEBUG output. All three variables default to 0 / off for now. Also, drop a small chunk of dead/useless code in the src/northbridge/via/cn700/raminit.c file, which would otherwise break compilation.

2008-12-09Add (parts of the) support for multiple DIMMs on the Intel 440BX chipset.Uwe Hermann
This is tested on hardware with four 128MB DIMMs and works ok, _iff_ you also fix additional registers (e.g. DRB, RPS, ...) for your setup.

Still hardcoded for Tyan S1846. This slightly increases performance, but it's still pretty horrible.

2007-05-28Lower the RAM init delays we use on the Intel 440BX.Uwe Hermann
As per JEDEC, we should wait 200us until voltages and clocks are stable. Then apply NOPs for 200 clock cycles (for simplicity we use 200us here).

- Only check the RAM from 0 - 640 KB and 768 KB - 1 MB now. That's available on all boards, regardless of what DIMMs you use. Tested on the Tyan S1846, works fine. - Properly set the PAM registers to allow the region from 768 KB - 1 MB to be used as normal RAM (required for the above). - Document all of this properly. Add/improve other documentation, too. - Simplify and document code in northbridge.c. - Cosmetics and coding style.

2007-04-01Initial Intel 440BX RAM initialization framework.Uwe Hermann
This does _not_ fully work, yet. You will _not_ be able to boot any payload with this code, yet. Add missing license headers. Base the northbridge.c file on the Intel 855PM version, that comes closer to what we want. The raminit.c file is written from scratch and hardcodes several values for now. This needs to be fixed later by reading the correct values via SPD.
