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. This requirement will be eliminated in another upcoming patch (i.e. all of the required settings will be auto-detected).

2008-10-01The ARRAY_SIZE macro is convenient, yet mostly unused. Switch lots ofCarl-Daniel Hailfinger
code to use it. That makes the code more readable and also less error-prone. Abuild tested. Signed-off-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net> Acked-by: Peter Stuge <peter@stuge.se> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@3624 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
2008-09-30A duplicate register address is incremented in table register_values.Mats Erik Andersson
A trivial fix to correct the address of the high byte in SDRAMC. Thus the leadoff timing IPDLT will be correctly referenced.

2007-10-27Drop duplicated and unneeded #defines from some northbridges (trivial).Uwe Hermann
This is generic PCI stuff, not nothbridge-specific in any way. The respective #defines are already present in src/include/device/pci_def.h. Abuild-tested, so shouldn't break anything.

2007-10-24Ever wondered where those "setting incorrect section attributes forStefan Reinauer

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.

2007-05-10Fixed a bug within the 440BX RAM size calculation. Since the DRB valuesCeri Coburn

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.

2006-07-29- Add support _framework_ for the Asus p2b. Richard Smith
- New superIO winbond/w83977tf - Add single memory controller SBbus debug routine into a file private to the i440bx This adds support the start of support for an Asus p2b mainboard. Current limitations are the same as for the Bitworks IMS board. Reads from the SMbus don't work. Moving dump_spd_registers() into its own private copy solves the problem of having to go hack on the version that included in src/sdram to only do one memory controller. git-svn-id: svn://svn.coreboot.org/coreboot/trunk@2351 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
2006-07-24add framework for i440bx chipsetRichard Smith
add support for NSC pc87351 SuperIO add Bitworks/IMS manboard config This is a very basic framework for the i440bx chipset and the Bitworks IMS board that uses it. Most things are structure only. Known issues: - SMbus reads to the RAM SPD come back all zero. - dump_spd_registers() is commented out since it breaks with the default setting of generic_dump_spd.c where it wants 2 memory controllers. git-svn-id: svn://svn.coreboot.org/coreboot/trunk@2347 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
