2022-10-14soc/amd/stoneyridge: use devicetree ops over pci driverFelix Held
Stoneyridge is a SoC so it makes sense to statically use ops instead of matching them to PCI DID/VID at runtime. In contrast to the other AMD SoCs in the coreboot tree the PC driver used the PCI ID of the first HT PCI device function, so add the ops to the device 0x18 function 0 devicetree entry in this patch.

2022-10-13soc/amd/stoneyridge: add chipset devicetreesFelix Held
Add chipset devicetrees for Stoneyridge and Carrizo, which is also supported by the Stoneyridge code, but has more external PCIe ports and devices. The mainboard's devicetrees will be changed to use the aliases defined in the chipset devicetree in follow-up patches. This is a preparation to statically assign the ops for the internal devices statically in the SoC devicetree instead of dynamically adding them in ramstage. BKDG #55072 Rev 3.04 was used to check the PCI devices and functions and the MMIO addresses.

2022-10-10soc/amd/common: Remove buildtime error for unknown cpuMartin Roth
This is not critical functionality and doesn't need a build-time error. Having it as a build time error causes a chicken & egg issue where the chipset needs to be added before it can be added to this file, but the header file fails the build because the chipset is unknown. It's not practical to exclude these files from the new platform builds because the PSP functionality is thoroughly embedded into the coreboot structure.

2022-09-15soc/amd: Do SMM relocation via MSRArthur Heymans
AMD CPUs have a convenient MSR that allows to set the SMBASE in the save state without ever entering SMM (e.g. at the default 0x30000 address). This has been a feature in all AMD CPUs since at least AMD K8. This allows to do relocation in parallel in ramstage and without setting up a relocation handler, which likely results in a speedup. The more cores the higher the speedup as relocation was happening sequentially. On a 4 core AMD picasso system this results in 33ms boot speedup. TESTED on google/vilboz (Picasso) with CONFIG_SMI_DEBUG: verify that SMM is correctly relocated with the BSP correctly entering the smihandler.

2022-08-25soc/amd: rework SPI flash MMIO region handlingFelix Held
Only 16 MByte of the SPI flash can be mapped right below the 4 GB boundary. In case of a larger SPI flash size, still only the 16 MByte region starting at 0xff000000 can be configured as WRPROT and be reserved for the MMIO mapped SPI flash region. The next 16 MByte MMIO region starting at address 0xfe000000 contain for example the LAPIC MMIO region, the ACPIMMIO region and the UART/I2C controller MMIO regions which shouldn't be configured as WRPROT. Reserving this region for the MMIO mapped SPI flash would also result in an overlap with the MMIO resources mentioned above. In the case of a smaller SPI flash, reserving the full 16 MByte flash MMIO region makes sure that the resource allocator won't try to put anything else in the lower parts of the 16 MByte SPI mapping region. To avoid the issues described above, always reserve/cache the maximum amount of 16 MBytes of flash that can be mapped below 4 GB. TEST=On boards with 16 MByte SPI flash chips, the resulting image of a timeless build doesn't change with this patch. Verified this on Chausie (Mendocino), Majolica (Cezanne), Cereme (Picasso) and Google/Careena (Stoneyridge). On Mandolin (Picasso) with an 8 MByte flash, the resulting image of a timeless build is different, but neither the coreboot console output nor the Linux dmesg output shows any errors that might be related to this change.

2022-08-12soc/(amd|rockchip): Update vb2ex_hwcrypto implementations to new API reqJulius Werner
We want to extend the vb2ex_hwcrypto APIs on the vboot side to allow passing 0 for the data_size parameter to vb2ex_hwcrypto_digest_init() (see CL:3825558). This is because not all use cases allow knowing the amount of data to be hashed beforehand (most notable the metadata hash for CBFS verification), and some HW crypto engines do not need this information, so we don't want to preclude them from optimizing these use cases just because others do. The new API requirement is that data_size may be 0, which indicates that the amount of data to be hashed is unknown. If a HW crypto engine cannot support this case, it should return VB2_ERROR_EX_HWCRYPTO_UNSUPPORTED to those calls (this patch adds the code to do that to existing HW crypto implementations). If the passed-in data_size value is non-zero, the HW crypto implementation can trust that it is accurate. Also reduce a bit of the console spew for existing HW crypto implementations, since vboot already logs the same information anyway.

2022-08-10mb/google/{zork,guybrush,skyrim},soc/amd/espi: Fix vw_irq_polarityRaul E Rangel
The default state for the IRQ lines when the eSPI controller comes out of reset is high. This is because the IRQ lines are shared with the other IRQ sources using AND gates. This means that in order to not cause any spurious interrupts or miss any interrupts, the IO-APIC must use a low polarity trigger. On zork/guybrush/skyrim the eSPI IRQs are currently working as follows: * On power on/resume the eSPI controller drives IRQ 1 high. * eSPI controller gets configured to not invert IRQ 1. * OS configures IO-APIC IRQ 1 as Edge/High. * EC writes to HIKDO (Keyboard Data Out) which causes the EC to set IRQ1 high. * eSPI controller receives IRQ 1 high, doesn't invert it, and leaves IRQ 1 as high. This results in missing the first interrupt. * When the x86 reads from HIKDO, the EC deasserts IRQ1. This causes the eSPI controller to set IRQ1 to low. We are now primed to catch the next edge high interrupt. This is generally not a problem since the linux driver will probe the 8042 with interrupts off. On S3/S0i3 resume since the eSPI controller comes out of reset driving the IRQ lines high, we trigger a spurious IRQ since the IO-APIC is configured to trigger on edge high. This results in the 8042 controller getting incorrectly marked as a wake trigger. By configuring the IO-APIC to use low polarity interrupts, we no longer lose the first interrupt. This also means we can use a level interrupt to match what the EC actually asserts. We use the `Interrupt` keyword instead of the `IRQ` keyword in the ACPI because the linux kernel will ignore the level/polarity parameters for the `IRQ` keyword and default to `edge/high. `Interrupt` doesn't have this problem. The PIC is not currently configured anywhere and it defaults to an edge/high trigger. We could add some code to configure the PICs trigger register, but I don't think we need the functionality right now. For zork and guybrush, this change is a no-op. eSPI is configured in verstage which is located in RO, and we have already locked RO for these devices. We will need to figure out how to properly set the `vw_irq_polarity` for these devices.
