2020-08-11nb/intel/sandybridge/raminit: Add ECC debug codePatrick Rudolph
* Add ECC test code when DEBUG_RAM_SETUP is enabled * Move ECC scrubbing after set_scrambling_seed() to be able to observe what has been cleared in the test routine. If clearing happens before set_scrambling_seed the data is XORed with a different PRN. Data read from memory will look random instead of all zeros. * ECC scrubbing must happen after dram_dimm_set_mapping() The ECC logic is set to "normal mode" in dram_dimm_set_mapping(). In normal mode the ECC bits are calculated and stored on write transactions. * Move method out of try_init_dram_ddr3(). This satisfies point 2 and point 3 of the list above.

2015-10-03sandybridge ivybridge: Treat native init as first class citizenAlexandru Gagniuc
This is a sad story. We have three different code paths for sandybridge and ivybridge: proper native path, google MRC path, and, everyone's favorite: Intel FSP path. For the purpose of this patch, the FSP path lives in its own little world, and doesn't concern us. Since MRC was first, when native files and variables were added, they were suffixed with "_native" to separate them from the existing code. This can cause confusion, as the suffix might make the native files seem parasitical. This has been bothering me for many months. MRC should be the parasitical path, especially since we fully support native init, and it works more reliably, on a wider range of hardware. There have been a few board ports that never made it to coreboot.org because MRC would hang. gigabyte/ga-b75m-d3h is a prime example: it did not work with MRC, so the effort was abandoned at first. Once the native path became available, the effort was restarted and the board is now supported. In honor of the hackers and pioneers who made the native code possible, rename things so that their effort is the first class citizen.

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>
