2024-10-09soc/amd/common/psp: add and call PSP SMI SPI RPMC function stubsFelix Held
In the case where the x86 owns the SPI controller and the RPMC feature is used, the PSP will send an SMI to the x86 side for it to send the RPMC increment monotonic counter and RPMC request monotonic counter commands to the SPI flash and return the result to the PSP. Add stubs as handlers for those two PSP SMI commands.

2024-09-09soc/amd/cezanne: Add an option to enable A/B recovery schemeZheng Bao
Extracted from NDA spec #56995: "The A/B recovery scheme formally separates the SPI flash space into different partitions; a primary, “A” and secondary, “B”, which hold the same set of system firmware. Under this scheme, the partitions A and B can hold identical contents initially, but each partition can be updated individually. Normally the system boots from partition A, but if the A partition is found to be corrupted, the system will switch to partition B and boot. The OEM BIOS can then choose to continue the boot from partition B, or repair partition A using contents from partition B." The Cezanne platform supports both A/B recovery and no recovery method. It needs this flag passed to amdfwtool to enable the A/B recovery layout.

2024-08-27soc/amd/stoneyridge/smihandler: add PSP SMI handlerFelix Held
Now that the PSP SMI handler for flash access is also implemented for the PSP generation 1, the PSP SMI handler can be added to the Stoneyridge code too. The actual PSP SMI handler code will only be added to the build when SOC_AMD_COMMON_BLOCK_PSP_SMI is selected which isn't the default case, so this patch doesn't change the current behavior unless that option is also selected. This SMI handler mainly added for completeness since the PSP firmware blobs released for Stoneyridge are probably lacking the corresponding PSP-side code to send the PSP SMI to the host. At least if I remember correctly the PSP bootloader release for Stoneyridge has the ability to load the secure OS removed and since the secure OS is the runtime component, some part of that is probably what's sending those SMIs to the host. If there are some other PSP bootloader builds that support loading the secure OS, this patch might still be useful for those.

2024-08-07soc/amd/common/psp_smi: implement P2C mailbox handlingFelix Held
When the PSP wants to access the SPI flash during runtime, but isn't the owner of the SPI flash controller, it sends an SMI to the x86 side. The corresponding SMI handler then checks the P2C (PSP to core) mailbox for the command and data, processes the command, and if needed puts the requested data into the P2C buffer. The P2C mailbox is a memory region in TSEG aka SMM memory. Both location and size are communicated to the PSP via the PSP SMM info mailbox command which is sent right after mpinit is done. This commit adds the code to access the P2C mailbox to the PSP SMI handler code, but the handling of the actual mailbox commands the PSP sends to the SMI handler is added in later patches to keep the patch size manageable.

2024-07-25soc/amd/common/psp_gen2: use MMIO access againFelix Held
Now that we have a get_psp_mmio_base function that will work on all SoCs that use the psp_gen2 code, we can move back to accessing the PSP registers via their MMIO mapping. This sort-of reverts commit 198cc26e4951 ("soc/amd/common/block/psp/psp_gen2: use SMN access to PSP"). When doing SMN accesses from the SMI handler after the OS has taken over ownership of the platform, there's the possibility to cause trouble by clobbering the SMN access index register from SMM. So that should be either avoided completely or the SMI code needs to save and restore the original contents of the SMN index register. The PSP MMIO base will be set up by the FSP before the resource allocation in coreboot and be treated like a fixed resource by the allocator. The first SMI where corresponding handler calls 'get_psp_mmio_base' happens when ramstage triggers the APM_CNT_SMMINFO SMI right after mpinit which happens after the resource allocation. So the PSP MMIO base address is expected to be configured and so the 'get_psp_mmio_base' function will cache the base address and won't need to do any SMN access in subsequent calls that might happen after the OS has take over control. This isn't currently an issue, since the only PSP mailbox command from the SMI handler after coreboot is done and the OS has taken over will be during the S3/S4/S5 entry, and this will be triggered by the OS as the last step after it is done with all its preparations for suspend/ shutdown. There will however be future patches that add SMI-handlers which can send PSP mailbox commands during OS runtime, and so we have to make sure we don't clobber the SMN index register. TEST=PSP mailbox commands are still sent correctly on Mandolin.

2024-07-25soc/amd/common/block/psp_gen2: add get_psp_mmio_baseFelix Held
Add get_psp_mmio_base which reads the PSP MMIO base address from the hardware registers. Since this function will not only be called in ramstage, but also in SMM, we can't just look for the specific domain resource consumer like it is done for the IOAPICs in the northbridge, but have to get this base address from the registers. In order to limit the performance impact of this, the base address gets cached in a static variable if an enabled PSP MMIO base register is found. We expect that this register is locked when it was configured and enabled; if we run into the unexpected case that the PSP MMIO register is enabled, but not locked, set the lock bit of the corresponding base address register to be sure that it won't change until the next reset and that the hardware value can't be different than the cached value. This is a preparation to move back to using MMIO access to the PSP registers and will also enable cases that require the use of the MMIO mapping of the PSP registers.

2024-07-25soc/amd: Ensure bank 0 is selected before accessing VBNV in CMOSYu-Ping Wu
In AMD platforms, the bit 4 of CMOS's Register A (0x0a) is DV0 bank selection (0 for Bank 0; 1 for Bank 1) [1]. Since the MC146818 driver accesses VBNV via Bank 0, the bit must be cleared before we can save VBNV to CMOS in verstage. Usually there's no problem with that, because the Register A is configured in cmos_init() in ramstage. However, if CMOS has lost power, then in the first boot after that, the bit may contain arbitrary data in verstage. If that bit happens to be 1, then CMOS writes in verstage will fail. To fix the problem, define vbnv_platform_init_cmos() to call cmos_init(0), which will configure the Register A and therefore allow saving VBNV to CMOS in verstage.

2024-05-23device: drop unnecessary CHECK_REV_IN_OPROM_NAME optionFelix Held
The CHECK_REV_IN_OPROM_NAME Kconfig option was introduced to solve the problem of the PCI VID/DID combination of the Picasso iGPU not being sufficient information to know which VGA BIOS file to run, so a new function that additionally checks the PCI revision of that device was introduced. Later it turned out that there might be a case where even that isn't sufficient, so the soc_is_raven2() function is used in the remap function to always use the correct VBIOS file. Picasso is the only SoC that selected the CHECK_REV_IN_OPROM_NAME Kconfig option, so all other SoCs are unaffected by this change. Now that we use the VBIOS images with only the PCI VID and DID in the CBFS file name for Picasso, SeaBIOS will find the VBIOS with the same ID as the iGPU in CBFS and we don't need the workaround to add a third VBIOS image via VGA_BIOS_DGPU_* that has the name that SeaBIOS expects. This will result in SeaBIOS now running the VBIOS that has the same PCI VID/DID as the hardware which will be the wrong one in the RV2 silicon showing the PCO silicon PCI VID/DID, but that was also the case with the VGA_BIOS_DGPU_* workaround where the board's Kconfig just selected one of the two possible images during build time and hoped that it was the correct one for that actual hardware. The only board where this patch might cause a regression compared to the old behavior is the AMD Cereme reference board with Pollock APU, but I'm not even sure if any coreboot developer still has one of those boards, so I'm willing to accept that. To properly solve the problem with SeaBIOS using the correct VBIOS file in all cases, we'd need to generate that info during coreboot runtime and somehow pass it to SeaBIOS, but that's out of scope for this patch. TEST=On Mandolin with PCO silicon, the display output in both SeaBIOS and Ubuntu still works. Booting Windows 10 via the pre-built EDK2 payload that I'm using also resulted in the display output working.

The static configuration in the devicetree assumes that the default WLAN0_WWAN0 is selected; for the other cases we'll still need to fix up things accordingly in the mutable devicetree. The WLAN01 and WWAN01 cases still need to be handled in a follow-up patch. Since openSIL currently doesn't use the info from the gpio_group struct element, but deasserts both PCIe reset pins GPIO 26 and 27, the gpio_group isn't specified in the chip configuration in the devicetree.

The chip drivers in the devicetree use the path where the corresponding chip.h file resides both to include this chip.h file in the static.c generated by util/sconfig from the devicetree and also for the names of the chip config and chip ops struct. To be able to build a SoC using either the MPIO chip driver from the openSIL stub or from the actual openSIL glue code without needing different devicetree files for the different cases, introduce a common MPIO chip.h file that then includes the correct MPIO header file. The chip config and ops structures also need to be renamed to take this change into account. Thanks to Matt for pointing out how to make the path to the actual MPIO chip.h file configurable via a Kconfig setting. This allows overriding this path from site-local without the need to have any reference to site-local in the upstream code.

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.

2024-03-28soc/amd/non_car/memlayout_x86.ld: Top align the codeArthur Heymans
This does the following: - Top align the bootblock so that the only the memory needed gets used. This might slightly reduce the time the PSP needs to decompress the bootblock in memory - Use a memory directive to assert that the 16bit code is inside the top 64K segment - Use the program counter less. While the BDF linker is happy about running the program counter backwards, LLD is not. There is no downside to this. - Use a symbol rather that the program counter for sections. LLD gets confused when (.) is used along with '<': it places the section at the start of the memory region, rather than at the program counter. Using a variable name works around this. - Use a 'last_byte' section to make sure the first instruction is at 0xfff0. Both the BDF and the LLD linkers seems to work well with this code TEST: Both BFD and LLD are able to link the bootblock Change-Id: I18bdf262f9c358aa01795b11efcb863686edc79c Signed-off-by: Arthur Heymans <arthur@aheymans.xyz> Reviewed-on: https://review.coreboot.org/c/coreboot/+/81433 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Martin L Roth <gaumless@gmail.com>
2024-03-28security/tpm: resolve conflicts in TSS implementationsSergii Dmytruk
No functional changes. Refactor code such that there won't be any compiler or linker errors if TSS 1.2 and TSS 2.0 were both compiled in. One might want to support both TPM families for example if TPM is pluggable, while currently one has to reflash firmware along with switching TPM device.

2024-03-23soc/amd/common/noncar/memmap: reduce visibility of memmap_early_dramFelix Held
The memmap_early_dram struct is now only used inside the non-CAR memmap.c, so move the struct definition there.

2024-03-23soc/amd/common/cpu/noncar/memmap: use VGA MMIO defines everywhereFelix Held
Only the VGA MMIO range used the VGA_MMIO_* defines, but instead of using constants for the end of the region before that and the beginning of the region after that, the VGA_MMIO_* defines can be used.
