2024-05-14soc/intel/xeon_sp: Add Granite Rapids initial codesShuo Liu
coreboot GNR (Granite Rapids) is a FSP 2.4 based, no-PCH, single IO-APIC Xeon-SP platform. The same set of codes is also used for SRF (Sierra Forest) SoC. This patch initially sets the code set up as a build target with Granite Rapids N-1 FSP (src/vc/intel/fsp/fsp2_0/graniterapids). 1. All register definitions are forked from SPR (Sapphire Rapids) and EBG (Emmitsburg PCH)'s codes are reused. 2. src/soc/intel/xeon_sp/chip_gen6.c is newly added as chip common codes for 6th Gen Xeon-SP SoC (Granite Rapids) and later.

The original code uses TRE0-TRE3 register to determine whether or not the TBT controller exists. However, there is a remap in fsp could confuse the TRPx._STA. Ex: Disable TBT controller 0 on b:0 d:7 f:0 Enable TBT controller 1 on b:0 d:7 f:1 The FSP will do the remap and after the remap: TBT controller 1 is on b:0 d:7 f:0 TBT controller 0 is on b:0 d:7 f:1 This is becuase func 0 must exist per pci spec. However, the TRE0-TRE3 will not be remapped so that the ACPI TRPx._STA method could be confused. In such scenario, TRP0._STA will return 0x0, TRP1._STA will return 0xf which is wrong because TBT controller 1 is now at b:0 d:7 f:0 TEST=tested on rex and _TRPx._STA returns correctly.

2024-04-29soc/intel/cmn/graphics: Make DDI-A 4 lanes configurableAngel Pons
As described in Intel document 336464 (8th gen S series datasheet volume 1), the CPU's 4 eDP lanes can be bifurcated, so that DDI-A (eDP) ends up with 2 lanes, and DDI-E (DP, typically used for VGA) has the remaining 2 lanes. This lets mainboards provide a VGA output without sacrificing one of the main 4-lane DDIs. Newer platforms seem to be lacking this. However, the way this is structured in coreboot does not allow boards to choose whether bifurcation should be enabled. Most boards in the tree do not use DDI-E (it doesn't exist on mobile platforms), but there are some boards (e.g. hp/280_g2) that use DDI-E and a DP-to-VGA converter chip to provide a VGA output. Replace `SOC_INTEL_CONFIGURE_DDI_A_4_LANES` with two new Kconfig options to allow boards to decide. Use `SOC_INTEL_GFX_HAVE_DDI_A_BIFURCATION` to specify whether a platform supports DDI-A bifurcation at all (do nothing otherwise, maintaining the original code's behaviour). If bifurcation is supported, the `SOC_INTEL_GFX_ENABLE_DDI_E_BIFURCATION` is used to clear or set the `DDI_A_4_LANES` bit in the `DDI_BUF_CTL_A` register.

2024-04-03cpu/x86/topology: Add node ID parserPatrick Rudolph
Currently the SRAT table only exposes one proximity group as it uses the LAPIC node_id, which is always initialized to 0. Use CPUID leaf 0x1f or 0xb to gather the node ID and fill it to make sure that at least one proximity group for every socket is advertised. For now the SNC config isn't taken into account.

2024-03-28cpu/x86: Link page tables in stage if possibleArthur Heymans
When switching back and forth between 32 to 64 bit mode, for example to call a 32-bits FSP or to call the payload, new page tables in the respective stage will be linked. The advantages of this approach are: - No need to determine a good place for page tables in CBFS that does not overlap. - Works with non memory mapped flash (however all coreboot targets currently do support this) - If later stages can use their own page tables which fits better with the vboot RO/RW flow A disadvantage is that it increases the stage size. This could be improved upon by using 1G pages and generating the pages at runtime. Note: qemu cannot have the page tables in the RO boot medium and needs to relocate them at runtime. This is why keeping the existing code with page tables in CBFS is done for now.

2024-03-19soc/intel/xeon_sp/spr: Enable 512 MMCONF buses by defaultPatrick Rudolph
As of now coreboot only supported one PCI segment group and thus the MMCONF size had to be limited to 256 buses on ibm/sbp1. Since the default FSP doesn't allow to disable unused IIO stacks a patched version had to be used. Those unused IIO stacks consume lots of PCI bus ranges, leaving no free buses for the secondary side behind PCI bridges. The IIO disable mechanism doesn't work after ACPI G3 exit and thus requires multiple reboots when the previous state was G3. Since coreboot now supports multi PCI segment groups enable 512 MMCONF buses on 4S platforms by default and drop the IIO stack disable UPDs on ibm/sbp1. This allows to boot faster without the need for a patched FSP. The use of multiple PCI segment groups might prevent legacy software from working properly, however the only board where multiple PCI segment groups are used uses u-root as default payload.

This patch moves commonlib/stdlib.h -> commonlib/bsd/stdlib.h, since all code is BSD licensed anyway. It also moves some code from libpayloads stdlib.h to commonlib/bsd/stdlib.h so that it can be shared with coreboot. This is useful for a subsequent commit that adds devicetree.c into commonlib. Also we don't support DMA on arm platforms in coreboot (only libpayload) therefore `dma_malloc()` has been removed and `dma_coherent()` has been moved to architecture specific functions. Any architecture that tries to use `dma_coherent()` now will get a compile time error. In order to not break current platforms like mb/google/herobrine which make use of the commonlib/storage/sdhci.c controller which in turn uses `dma_coherent` a stub has been added to arch/arm64/dma.c.
