2016-04-11and/nb/mct_ddr3: Pack all structures passed to ramstage and set alignmentTimothy Pearson
Two of the MCT data structures passed as substructures to ramstage were not packed, and additionally no alignment was specified. On at least SP5100-based platforms, specifying packed with no alignment caused boot failure dependent on the exact compiled binary layout (LPC hang). Specifying the alignment and packing the remaining structures appears to have resolved the remaining LPC hang issues on the KGPE-D16. Note that packing the remaining structures alone was not sufficient to eliminate the hang, however removing the packed attribute entirely (during debugging) did resolve the hang at the expense of potential problems in ramstage.

This reverts commit f961becc433bf23fc8744fdfd757f0cdb75c2c62. On studying the BKDG more closely this is not the correct place to enable DIMM parity.

2016-04-08nb/amd/mct_ddr3: Cache whether ECC is allowed at the platform levelTimothy Pearson
Certain AMD platforms, such as those using the SP5100 southbridge, contain a very poorly documented bug related to LPC ROM access, which is triggered by repeated (hundreds or more) rapid calls to get_option(). This bug manifests as a complete system deadlock in ramstage device configuration, requiring standby power to be removed from the system to release the deadlock. Cache the platform ECC status to avoid repeated calls to get_option() in the lane count detection logic.

2016-03-31nb/amd_mct_ddr3: Move DRAM MCE sync flood enable to ramstageTimothy Pearson
Enabling sync flood on DRAM MCE directly after ECC clear can lead to a system hang with no way to determine the offending DRAM module. Clear MCEs after ECC setup, but do not enable sync flood until NB setup in ramstage to allow time for any MCEs to accumulate in the status registers. Before enabling sync flood on MCE, determine if any MCEs were logged during ramstage execution and display them on the serial console. Also clear the DRAM ECC sync flood bits during DRAM training and initial ramstage execution.

DRAM training accounts for most of the romstage startup time, yet if the hardware configuration has not changed from the previous boot the previously discovered training values are still valid. Use them if the DIMM configuration has not changed since the last boot. The SPD values of all installed DIMMs are hashed and stored in the S3 resume data area of the main system Flash device. If a DIMM is changed the hash will almost certainly change as well, forcing retraining on next boot.

Upon bootup the hardware reads at minimum 256 * 16 bytes (4Kb, or 32KB) over I2C on a system with all DIMM slots populated. If even one of those reads has a single flipped bit in it (due to EMI, cross coupling with another trace, or just poor margins on some cheap DIMM) the system will hang and require a hard reset. In practice I've seen failure rates as high as 1 failed boot in 50 due to this issue, granted with cheap DIMMs, but even so retrying the read resolves the corruption issue. I2C is not designed for continuous data transmission with high reliability, and there is no hardware error checking, therefore a single retry when transferring this amount of data makes sense.

It encourages users from writing to the FSF without giving an address. Linux also prefers to drop that and their checkpatch.pl (that we imported) looks out for that. This is the result of util/scripts/no-fsf-addresses.sh with no further editing.

2015-10-26northbridge/amd/amdmct: Fix broken AMD K10 DDR3 memory initalizationTimothy Pearson
The native AMD DDR3 memory initialization code was riddled with numerous errors and was missing critical configuration code segments; this made it so that DDR3 memory did not function on most AMD boards. This patch corrects enough of the DDR3 initialization such that UDIMMs can be used on most channels of G34 Opteron boards. Further work is needed to fix the broken RDIMM code and remaining UDIMM issues.

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>
