2009-01-20This fine work by Jon Dufresne was awkwardly rotting on the mailing list forJon Dufresne
almost three years. Let's put it somewher so people find it if they're looking for it. Someone dare sending a late announcement to the coreboot-announce list? :-) Add (preliminary) support for Intel 855GME (Mobile version of the 855) chipset to coreboot. There are some holes in the code to be filled out, but unlike the code for the 855pm this has booted a mainboard before.

2009-01-16First part of heterogenous dualchannel support.Carl-Daniel Hailfinger
Do not allow non-identical DIMMs yet, but prepare the code. Calculate tCL related settings per DIMM in a dual channel setup. The check for compatibility will come in a later patch, but since DIMMs still have to be identical, this does not hurt. Factor out tRC calculation to prepare for per-DIMM calculation. Add diagnostic messages to tRC code. Test booted to FILO, behaviour is identical if you ignore the added debug messages (which are switched off by default).

2009-01-16Refactor K8 rev F DDR2 CL timing retrieval.Carl-Daniel Hailfinger
This will allow usage of compatible DIMMS in a dual channel setup instead of requiring the DIMMS to be identical.

2009-01-16Since all K8 targets now have CONFIG_USE_PRINTK_IN_CAR enabled, usingCarl-Daniel Hailfinger
print_* in K8 RAM init does not make sense anymore. Convert almost all print_* to printk_*. This improves readability a lot and makes the code shorter. Reorder the SPD equality checks in the dual channel DIMM compatibility checking code. This is to make sure that we know if any other mismatches are present in the DIMM. The new order eases debugging with the old code. Add a comment about false negatives in that code. This needs to be implemented correctly, but that is hard to do in an efficient way. Check if the DIMMS in a dual channel setup have any compatible CAS latencies. Add better comments to explain why wrong-at-first-glance SPD CL walking code is actually correct. Fix a few typos.

2008-12-23Add verbose debugging output at SPEW level to noncoherent HyperTransportCarl-Daniel Hailfinger
initialization. This patch has helped immensely to track down a bug in 690G ncHT init. It depends on my earlier patch which enables CONFIG_USE_PRINTK_IN_CAR for all boards using HT. Of course that means ROMCC is not an option anymore for those boards, but I don't think that's a big problem. Another way to solve this would be #defining printk_spew to nothing.

2007-06-19This patch fixes up a couple mistakes I made with the i82810 and mew-vw to makeCorey Osgood
the system boot to a command line. This patch comments out the code to set up the vga framebuffer to allow the system to boot, without this fix the system hangs during elfboot. The only line that is absolutely necessary to change is the SMRAM setup, however I've commented out all vga setup to make it very obvious to both the kernel/payload and anyone looking at the code that vga isn't currently working. This setup might also be better handled in northbridge.c, if it doesn't need to be done before ram init, yet another reason to comment it all. In the future, LinuxBIOS needs to be told that the graphics memory area, 1mb or 512kb (at the user or developer's option), is reserved for the onchip vga, but I'm not sure if it's taken at the top or bottom of the memory, yet. LB may also need to set a base address for the AGP aperture and/or be told that range is reserved as well, whether this was originally the job of the system bios or vga bios is still a mystery. It also corrects the number of entries in irq_tables.c, without this fix the kernel would probably complain and hang due to unmapped IRQs.

2007-06-07Minor tweaks in the 440BX RAM init code (trivial).Uwe Hermann
Still hardcoded for Tyan S1846. This slightly increases performance, but it's still pretty horrible. Some RAM settings are causing a dramatically slow system (confirmed by comparing memtest performance results of the proprietary BIOS and our code). Haven't found the problem, yet.

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). All other delays are so low that we get away with just waiting 1us.

2007-05-27Various 440BX and Tyan S1846 related minor changes and fixes (trivial):Uwe Hermann
- 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.
