2010-03-17From Keith Hui:Keith Hui
This patch implements a full SDRAM buffer strength programming algorithm in set_dram_buffer_strength(), checked against my P2B-LS factory BIOS. With this in place, I now have 133MHz (!) stability with three 256MB PC133 modules, and can boot Fedora 11 all the way to the init daemon (actually upstart, but that's another story). Not to login prompt yet. We'll find out why later. This again assumes a 4-DIMM board because that's all I have. I need someone with a 3-DIMM board to test it. As a bonus, there's a big comment block within that illustrates the algorithm. :-) Signed-off-by: Keith Hui <buurin@gmail.com> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5238 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
2010-03-13Add SDRAMPWR_4DIMM Kconfig option (not user-visible in menuconfig).Keith Hui
Each Intel 440BX board should select this option if it has 4 DIMM slots on the PCB, and _not_ select it (it defaults to 'n') if it has 3 DIMMs on the PCB.

2010-03-05This patch is from 2009-10-20Uwe Hermann
Convert all DEBUG_SMBUS, DEBUG_SMI, and DEBUG_RAM_SETUP custom and local #defines into globally configurable kconfig options (and Options.lb options for as long as newconfig still exists) which can be enabled by the user in the "Debugging" menu. The respective menu items only appear if a board is selected where the chipset code actually provides such additional DEBUG output. All three variables default to 0 / off for now. Also, drop a small chunk of dead/useless code in the src/northbridge/via/cn700/raminit.c file, which would otherwise break compilation.

2009-09-25some progress on kconfig:Patrick Georgi
- northbridges are done - southbridges are done - Intel CPUs are done, with a design that the board only has to specify the socket it has, and the CPUs are pulled in automatically. There is some more cleanup possible in that area, but I'll do that later - a couple more mainboards compile: - intel/eagleheights - intel/jarrell - intel/mtarvon - intel/truxton - intel/xe7501devkit - sunw/ultra40 - supermicro/h8dme - tyan/s2850 - tyan/s2875 - via/epia - via/epia-cn - via/epia-m - via/epia-m700 - via/epia-n - via/pc2500e (PPC not considered, probably overlooked something) All of them only _build_, but some options are probably completely wrong.

2009-07-02Move the v3 resource allocator to v2.Myles Watson
Major changes: 1. Separate resource allocation into: A. Read Resources B. Avoid fixed resources (constrain limits) C. Allocate resources D. Set resources Usage notes: Resources which have IORESOURCE_FIXED set in the flags constrain the placement of other resources. All fixed resources will end up outside (above or below) the allocated resources. Domains usually start with base = 0 and limit = 2^address_bits - 1. I've added an IOAPIC to all platforms so that the old limit of 0xfec00000 is still there for resources. Some platforms may want to change that, but I didn't want to break anyone's board. Resources are allocated in a single block for memory and another for I/O. Currently the resource allocator doesn't support holes. Signed-off-by: Myles Watson <mylesgw@gmail.com> Acked-by: Ronald G.

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).

- 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.
