2024-02-08commonlib: Change GCD function to always use 64 bitsJulius Werner
It seems that we have some applications where we need to calculate a GCD in 64 bits. Now, we could instantiate the algorithm multiple times for different bit width combinations to be able to use the most efficient one for each problem... but considering that the function usually only gets called once per callsite per stage, and that software emulation of 64-bit division on 32-bit systems doesn't take *that* long either, we would probably usually be paying more time loading the second instance of the function than we save with faster divisions. So let's just make things easy and always do it in 64-bit and then nobody has to spend time thinking on which version to call.

2024-02-02lib: Move IP checksum to commonlibJulius Werner
This patch moves the IP checksum algorithm into commonlib to prepare for it being shared with libpayload. The current implementation is ancient and pretty hard to read (and does some unnecessary questionable things like the type-punning stuff which leads to suboptimal code generation), so this reimplements it from scratch (that also helps with the licensing). This algorithm is prepared to take in a pre-calculated "wide" checksum in a machine-register-sized data type which is then narrowed down to 16 bits (see RFC 1071 for why that's valid). This isn't used yet (and the code will get optimized out), but will be used later in this patch series for architecture-specific optimization.

2024-01-31include/device/device.h: Remove CHIP_NAME() macroNicholas Sudsgaard
Macros can be confusing on their own; hiding commas make things worse. This can sometimes be downright misleading. A "good" example would be the code in soc/intel/xeon_sp/spr/chip.c: CHIP_NAME("Intel SapphireRapids-SP").enable_dev = chip_enable_dev, This appears as CHIP_NAME() being some struct when in fact these are defining 2 separate members of the same struct. It was decided to remove this macro altogether, as it does not do anything special and incurs a maintenance burden.

2024-01-29device/device.h: Drop multiple linksArthur Heymans
Multiple links are unused throughout the tree and make the code more confusing as an iteration over all busses is needed to get downstream devices. This also not done consistently e.g. the allocator does not care about multiple links on busses. A better way of dealing multiple links below a device is to feature dummy devices with each their respective bus. This drops the sconfig capability to declare the same device multiple times which was previously used to declare multiple links.

2023-11-13nb/intel/sandybridge: Standardize MRC vs. native SPD mapping APIKeith Hui
Changes both MRC and native raminit code path to get SPD mapping from one place. Boards with all memory socketed specify their mappings in a devicetree setting introduced in commit 5709e03613b3 ("nb/intel/sandybridge: Migrate MRC settings to devicetree") back in May 2019 but remains unused as of this patch. This setting will now hold raw SMBus addresses, and MRC raminit gets code to translate them into a representation MRC expects. Boards with soldered down memory (specifically with HAVE_SPD_IN_CBFS in their board Kconfig), with or without socketed memory, specify their layouts in mb_get_spd_map() as used by Haswell boards, where they access hardware GPIO straps to select which SPD data to use. This harmonizes the way boards specify their SPD layouts across Haswell/SNB/IVB boards whether using MRC or native raminit. Going forward they only need to specify the layout in one place. (Going forward the devicetree setting should be backported to Haswell, once we get native raminit working there.) With this, northbridge code is now fully responsible for loading all SPD data, be it from CBFS or SMBus. To avoid breakage, transition will happen in stages: 1. This patch gets all the code in, and implements weak stubs that maintain existing code and data flow (i.e. mainboards still populate final SPD layout data). At this point devicetree already uses new representation, but is still unused meaning no breakage. 2. Follow-up patch(es) remove mainboard_get_spd() from mainboards, and replace it with mb_get_spd_map() or devicetree values (as appropriate) with converted SPD info. The "weak" mainboard_get_spd() with new logic takes over. Boards go Haswell Style at this point. Boards with MRC raminit also lose code to fill in SPD data, allowing new data to take hold. 3. Clean-up patch removes the weak functions and public prototypes re mainboard_get_spd(), making it internal to northbridge. Changeover is complete.

2023-10-20x86: Add pre-memory stages CBFS cache scratchpad supportJeremy Compostella
Having a CBFS cache scratchpad offers a generic way to decompress CBFS files through the cbfs_map() function without having to reserve a per-file specific memory region. This commit introduces the x86 `PRERAM_CBFS_CACHE_SIZE' Kconfig to set the pre-memory stages CBFS cache size. A cache size of zero disables the CBFS cache feature. The default value is 16 KB which seems a reasonable minimal value enough to satisfy basic needs such as the decompression of a small configuration file. This setting can be adjusted depending on the platform needs and capabilities. We have set this size to zero for all the platforms without enough space in Cache-As-RAM to accommodate the default size.

2023-07-20acpi: Move ECAM resource below PNP0C02 device in a common placeArthur Heymans
From the Linux documentation (Documentation/PCI/acpi-info.rst): [6] PCI Firmware 3.2, sec 4.1.2: If the operating system does not natively comprehend reserving the MMCFG region, the MMCFG region must be reserved by firmware. The address range reported in the MCFG table or by _CBA method (see Section 4.1.3) must be reserved by declaring a motherboard resource. For most systems, the motherboard resource would appear at the root of the ACPI namespace (under \_SB) in a node with a _HID of EISAID (PNP0C02), and the resources in this case should not be claimed in the root PCI bus’s _CRS. The resources can optionally be returned in Int15 E820 or EFIGetMemoryMap as reserved memory but must always be reported through ACPI as a motherboard resource. So in order for the OS to use ECAM MMCONF over legacy PCI IO configuration, a PNP0C02 HID device needs to reserve this region. As no AMD platform has this defined in DSDT this fixes Linux using legacy PCI IO configuration over MMCONF. Tianocore messes with e820 table in such a way that it prevents Linux from using PCIe ECAM. This change fixes that problem.
