2013-06-04AMD Fam 15tn: Use all memory on systems with more than 4 GBSiyuan Wang
Take a Parmer board with 4G memory as an example. Use 'cat /proc/meminfo' to check memory, it reads 'MemTotal 3327540kB'. Parmer uses 512M as video memory when it has 4G. 3327540+512*1024 = 3851828(kB), so some memory is lost. When Parmer has 4G memory, TOM2 low is 0x1F000000, TOM2 high is 0x00000001. But in e820 table or coreboot table, the last item is 6: 0000000100000000 - 0000000118000000 = 1 RAM This is not correct, it should be 6: 0000000100000000 - 000000011f000000 = 1 RAM This patch changes the memory layout when TOM2 is set.

2013-04-11Persimmon/Fam14/SB800 DSDT: Split into common areasMike Loptien
Split the Persimmon DSDT into common code areas. For example, split the Southbridge specific code into the Southbridge directory and CPU specific code into the CPU directory. Also adding the superio.asl file to the Persimmon DSDT tree. This file is empty for the moment but will be necessary in the future. I have also emptied the thermal.asl file in the mainboard directory because it does not seem to perform as intended (fan control does not change when it is brought back into the code base) and it has been inside a '#if 0' statement for a long time. Removing it until it is decided that it is actually necessary. This change was verified in three different ways: 1. Visual comparison of the compiled DSDT pulled from the Persimmon after booting into Linux using the ACPI tools acpidump, acpixtract, and iasl. The comparison was done between the DSDT before and after doing the split work. This test is somewhat difficult considering the expanse of the changes. Blocks of code have been moved, and others changed. 2. Linux logs were dumped before and after the DSDT split. Logs dumped and compared include dmesg and lspci -tv. Neither log changed significantly between the two compare points. 3. The test suite FWTS was run on the Coreboot build both before and after doing the DSDT split with the command 'sudo fwts -b -P -u'. The flag -b specifies all batch jobs, -P specifies all power tests, and -u specifies utilities. Interactive jobs were not run as most of them consist of laptop checks. Again, there were no significant changes between the two endpoints. These tests lead me to believe that there was no change in the functionality of the ACPI tables apart from what is known and expected. This patch is the first of a series of patches to split the DSDT. The ASRock patch was merged before this one and breaks the ASROCK E350M1 build (patch 8d80a3fb: http://review.coreboot.org/#/c/3050/). Please be aware of this dependency when pulling these patches. Other patches that depend on this patch are 'AMD Fam14: Split out the AMD Fam14 DSDT' (http://review.coreboot.org/#/c/3051/) and 'Fam14 DSDT: Also return for unrecognized UUID in _OSC' (http://review.coreboot.org/#/c/3052/) Change-Id: I53ff59909cceb30a08e8eab3d59b30b97c802726 Signed-off-by: Mike Loptien <mike.loptien@se-eng.com> Reviewed-on: http://review.coreboot.org/3048 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth <martin.roth@se-eng.com>

2013-03-22x86: Unify arch/io.h and arch/romcc_io.hStefan Reinauer
Here's the great news: From now on you don't have to worry about hitting the right io.h include anymore. Just forget about romcc_io.h and use io.h instead. This cleanup has a number of advantages, like you don't have to guard device/ includes for SMM and pre RAM anymore. This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable. Potentially in the future some of the code in the io.h __PRE_RAM__ path should move to device.h or other device/ includes instead, but that's another incremental change.

2013-03-19AMD Fam15: Add SPD read functions to wrapper codeKimarie Hoot
Change: This is the initial step for moving the AMD F15 & HUDSON1,2,3 SPD-read callout out of the mainboard directories and into the wrapper. The next step is to update the platforms to use this routine in BiosCallouts.c and to delete the code from the mainboard directories. The DIMM addresses should be moved into devicetree.cb. If there are significant differences or reasons that the mainboard needs to override this code, it's perfectly reasonable to keep using the version in the mainboard, but this allows us to remove duplicated code and simplify the mainboard directories. Notes: This started by duplicating what was in Dinar, and was changed to use the devicetree.cb structures. Significant cleanup and magic number reduction was done as well. It is intended that this file will not be included in ramstage as the DIMM init is all done in romstage. This is similar to what was done for Parmer/Thatcher in commit 7fb692bd - http://review.coreboot.org/#/c/2190/ Fam15tn: Move SPD read from mainboards into wrapper Yes, it would make sense to split this into two separate files and move the SMBus initialization and access into the southbridge wrapper.

2013-01-30Extend CBFS to support arbitrary ROM source media.Hung-Te Lin
Summary: Isolate CBFS underlying I/O to board/arch-specific implementations as "media stream", to allow loading and booting romstage on non-x86. CBFS functions now all take a new "media source" parameter; use CBFS_DEFAULT_MEDIA if you simply want to load from main firmware. API Changes: cbfs_find => cbfs_get_file. cbfs_find_file => cbfs_get_file_content. cbfs_get_file => cbfs_get_file_content with correct type. CBFS used to work only on memory-mapped ROM (all x86). For platforms like ARM, the ROM may come from USB, UART, or SPI -- any serial devices and not available for memory mapping. To support these devices (and allowing CBFS to read from multiple source at the same time), CBFS operations are now virtual-ized into "cbfs_media". To simplify porting existing code, every media source must support both "reading into pre-allocated memory (read)" and "read and return an allocated buffer (map)". For devices without native memory-mapped ROM, "cbfs_simple_buffer*" provides simple memory mapping simulation. Every CBFS function now takes a cbfs_media* as parameter. CBFS_DEFAULT_MEDIA is defined for CBFS functions to automatically initialize a per-board default media (CBFS will internally calls init_default_cbfs_media). Also revised CBFS function names relying on memory mapped backend (ex, "cbfs_find" => actually loads files). Now we only have two getters: struct cbfs_file *entry = cbfs_get_file(media, name); void *data = cbfs_get_file_content(CBFS_DEFAULT_MEDIA, name, type); Test results: - Verified to work on x86/qemu. - Compiles on ARM, and follow up commit will provide working SPI driver.

This gets rid of the somewhat unstructured placement of AMD's sysinfo structure in CAR. We used to carve out some CAR space using a Kconfig variable, and then put sysinfo there manually (by "virtue" of pointer magic). Now it's a variable with the CAR_GLOBAL qualifier, and build system magic. For this, the following steps were done (but must happen together since the intermediates won't build): - Add new CAR_GLOBAL sysinfo_car - point all sysinfo pointers to sysinfo_car instead of GLOBAL_VAR - remove DCACHE_RAM_GLOBAL_VAR_SIZE - from CAR setup (no need to reserve the space) - commented out code (that was commented out for years) - only copy sizeof(sysinfo) into RAM after ram init, where before it copied the whole GLOBAL_VAR area. - from Kconfig Change-Id: I3cbcccd883ca6751326c8e32afde2eb0c91229ed Signed-off-by: Patrick Georgi <patrick@georgi-clan.de> Reviewed-on: http://review.coreboot.org/1887 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org> Reviewed-by: Marc Jones <marcj303@gmail.com>

PCIE devices are detected and initialized by the AMD PCIe init functions, which is in cimx rd890. The parameters are read from devicetree.cb before PCIe init. Now, all bridges and devices are trained on the device 0.0 enable. After PCIe init, the PCIe ports with devices are on and the PCIe ports without devices are off. so resources may be allocated correctly during the rest of the PCI scan. But if the devicetree was being used to enable/disable devices after initialization, the problems would arise.

There are four mainboards using agesa family15 code: Supermicro h8scm and h8qgi, Tyan s8226 and AMD dinar. All of these boards' PCI domain starts from 0x18.0. Take h8scm as an example, PCI devices from 0.0 to 0x14.5 is under 0x18.0. Now, the PCI domain's scan bus function stats from 0.0. This would result to the PCI devices be scanned twice. Because when the function run to device 18.0, it would scan from 0.0 again. This issue would result to 2 problems: 1) PCI device may be assigned two different PCI address. If this happenned on VGA device, coreboot maybe not load vga bios correctly. 2) coreboot initializes rd890's IO APIC twice. So this patch scans from 0x18.0 and could resolve the problems above.
