2012-04-27SMM: Add udelay on Sandybridge systemsStefan Reinauer
Cougar Point southbridge does udelay in SMM, hence add it on Sandybridge systems.

2012-04-21Intel e7505: enable ECC scrubbingKyösti Mälkki
It takes about 3 seconds to scrub 8GiB DDR266 RAM. After ECC scrub XIP cache is disabled for system stability. There is very little to do in romstage after ECC scrub, especially when RAM debug messages are turned off. So the delay caused by this is hardly noticeable. Cache for complete ROM is re-enabled before ramstage is decompressed, and it has no unstability issues. So the code required to re-enable cache for ROM currently already exists in cache-as-ram_ht.inc. A Kconfig option HW_SCRUBBER enables the scrub to be run on hard reboots and power-ons.

Drop comments (from e7501 era) which no longer seem to apply with e7505. Write the semi-constant D0:F0 table as code. Some register settings seem to be in different order compared with vendor BIOS, and will be handled by follow-up patches. Split RCOMP register copy function in two parts.

2012-04-17Intel e7505: handlers for undocumented registersKyösti Mälkki
Makes the code a bit more readable, IMO. There is no clean way to implement this as the affected registers are undocumented. Seems ROMCC cannot handle the enum. Also any of my future changes would not be even abuild tested as there is no longer a board with ROMCC and this chipset. E7505 chipset is CAR only from now on.

2012-01-31northbridge/intel/i945: CHECK_SLFRCS_ON_RESUME Kconfig optionPeter Stuge
Originally brought up by Sven Schnelle in March 2011 http://patchwork.coreboot.org/patch/2801/ http://www.coreboot.org/pipermail/coreboot/2011-March/064277.html On some mainboards it may be neccessary to reset early during resume from S3 if the SLFRCS register indicates that a memory channel is not guaranteed to be in self-refresh. On other mainboards, such as Lenovo X60 and T60, the check always creates false positives, effectively making it impossible to resume. The SLFRCS register is documented on page 197 of Mobile Intel® 945 Express Chipset Family Datasheet Document Number: 309219-006 which is publically available, and the register indicates if a memory channel is guaranteed to be in self-refresh mode (if bit = 1), or that a memory channel *may or may not be* in self-refresh mode (if bit = 0). The register can thus only be used to positively learn that memory is in self-refresh. It is not known for sure that memory is *not* in self-refresh. The register is reset by the PWROK signal, which *should* go low during S3, and go high again when resuming, so it is unsurprising that SLFRCS has already been cleared when we read the register. Sven's measurements of the CKE signal on a ThinkPad shows that memory remains in self-refresh indefinitely, until coreboot re-initializes the memory controller, even when SLFRCS bits were = 0. Boards which require a warm reset when SLFRCS bits are cleared must now explicitly enable the check in the mainboard Kconfig file. This commit selects the new option in all existing i945 mainboards. A follow-up commit will remove the option for ThinkPads.

2011-10-03TINY_BOOTBLOCK problem-fix on amdk8+amd8111 platformsenok71
The hp/dl145_g1 motherboard did not work since commit 1f7d3c5672ec90f8d71907b1a07c8a87fa461047 (svn 6124). That commit added TINY_BOOTBLOCK for amd8111 southbridge. The result was that the boot process stopped very early (no console output whatsoever). The same symptom was reported on other AMDK8 based boards with amd8111 southbridge chips. This commit seems to fix the bug. It adds a bootblock.c under src/northbridge/amd/amdk8 that calls enumerate_ht_chains. Probably the problem was that enum_ht_chains needs to be called before the southbridge bootblock.c function, not after.

On installing/starting Windows (tested with Win7 Ultimate) the system crashes with a Blue Screen of Death, reporting an ACPI BIOS error. From Scott Duplichan: To avoid the Windows BSOD, the uninitialized value TOM1 in the SSDT must be corrected. The attached patch does this. It uses the older patching method, and not the (possibly preferred) AML generation method. To simplify the patching operation, I moved the AML item 'TOM1' to the start of the SSDT. The patch also includes code to confirm the AML variable TOM1 is at the expected offset before patching. Also tested & working with Linux.

2011-03-08Enable mahogany_fam10 and Kino family 10h to run the SB HT link at the ↵Scott Duplichan
expected HT3 frequency and width by matching the BUID swap list to the production BIOS. In addition, the BUID swap list has been moved into the project-specific file romstage.c for the other 13 AMD family 10h projects as well. For projects using a desktop AMD family 10h processor, pasting in the mahogany_fam10 swap list will likely allow HT3 operation. This should be confirmed on real hardware before commiting any swap list change. A different swap list will be needed for server projects. For serengeti_cheetah_fam10, a reference BIOS swap list to try is: 0x00, 0x0A, 0x00, 0x06, 0xFF, 0x0A, 0x06, 0xFF. The patch makes these changes: 1) Remove the BUID swap list from ht_wrapper.c and put it in each of 15 romstage.c files where it is used (AMD family 10h projects). 2) Add a prototype to amdfam10.h. 3) Modify the swap list and test in real hardware for mahogany_fam10 and kino family 10h and confirm HT3 operation for the SB link.

CPU and northbridge frequency and voltage handling for Fam 10 in SVI mode. In fact I changed coreDelay before deleting the code in fidvid that called it. But there're still a couple of calls from src/northbridge/amd/amdmct/wrappers/mcti_d.c Since the comment encouraged fixing something, I parametrized it with the delay time in microseconds and paranoically tried to avoid an overflow at pathological moments.

CPU and northbridge frequency and voltage handling for Fam 10 in SVI mode. bits 13 - 15 of F3xd4 (StutterScrubEn, CacheFlushImmOnAllHalt and MTC1eEn are reserved for revisions D0 and earlier, so whe should not set them to 0 in fidvid.c config_clk_power_ctrl_reg0(...), called from prep_fid_change. For revisions > D0 (when we support them) it is ok not ot clear them, because they are documented as 0 on reset. bit 12 should be left alone according to BKDG. Should I set 11:8 ClkRampHystSel to 0 in the mask too, just to indicate we're touching them ? We'll OR them to 1111 anyway...

CPU and northbridge frequency and voltage handling for Fam 10 in SVI mode. Well, I understand it better like this, but maybe it's only me, part of the changes are paranoic, and the only effective change is for a factor depending on mobile or not that I can't test.

CPU and northbridge frequency and voltage handling for Fam 10 in SVI mode. Add an untested step in BKDG 2.4.2.8. I don't have the hardware with Core Performance Boost and I think it's only available in revision E that does not even have a constant yet.

CPU and northbridge frequency and voltage handling for Fam 10 in SVI mode. Add to init_fidvid_stage2 some step mentioned in BKDG 2.4.2.7 that was missing . Some lines are dead code now, but may handy if one day we support revison E CPUs.

CPU and northbridge frequency and voltage handling for Fam 10 in SVI mode. Looking at BKDG the process for updating Pstate Nb vid after warn reset seemed more similar to the codethat was there fo pvi than the one for svi, so I called the pvi function passing a pvi/svi flag. I don't find documentation on why should UpdateSinglePlaneNbVid() be called in PVI, but since I can't test it, I leave it as it was. This patch showed some progress beyond fidvid in my boar,d but only sometimes, most times it just didn't work.

CPU and northbridge frequency and voltage handling for Fam 10 in SVI mode. Factor out some common expressions. Add an error message when coreboots hangs waiting for a pstate that never comes (it happened to me), and throw some paranoia at it for good mesure. If I understood BKDG fam10 CPUs never need a software initiated vid transition, because the hardware knows what to do when you just request a Pstate change if the cpu is properly configured. In fact unifying a little what PVI and SVI do was better for my board (SVI). So I drop transitionVid, which I didn't understand either (why did it have a case for PVI if it is never called for PVI ? Why did the PVI case distinguigh cpu or nb when PVI is theoretically single voltage plane ? ).
