The ELOG for CSE updates was being added in fsp_params.c, but the actual update happens in cse_lite.c. This commit moves the ELOG to cse_lite.c to more accurately reflect where the event is happening. This also removes the need for a sol_type variable in meteorlake/romstage/fsp_params.c.

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.

2024-09-09soc/intel/xeon_sp: Reserve MMIO high rangeShuo Liu
Xeon-SP supports MMIO high range, a.k.a. MMIO range above 4G. FSP will assign domain MMIO high windows from this range. However, there will be unassigned parts among these high windows for non-domain device usage (e.g. misc devices belonging to an IIO stack but not belonged to any PCIe domains under that stack). This will cause segmentation in MTRR UC coverage. For example, in SPR-XCC where only CPM0/HQM0 are supported and instantiated to PCIe domains, MMIO ranges are still reserved for CPM1/HQM1. See more at src/soc/intel/xeon_sp/spr/ioat.c. Reserve MMIO high range as a whole under domain0/00:0.0. During MTRR calculation, this reservation will connect the discontinued domain MMIO high windows together to form one continuous range, and save MTRR register usage from inadequacy. This change is initially raised for SPR but could be effective for GNR as well. TESTED = Build and boot in intel/archercity CRB, MTRR register usage decreases from 7 to 3 in 2S system.

2024-09-07drivers/intel/fsp2_0: Add Kconfig option to control MBP HOB creationSubrata Banik
This patch adds a new Kconfig option `FSP_PUBLISH_MBP_HOB` to control the creation of the ME_BIOS_PAYLOAD_HOB (MBP HOB) by FSP. Disabling this option can improve boot time on platforms that do not utilize the MBP HOB, such as ChromeOS devices. The option is disabled by default on ChromeOS and enabled by default on other platforms. On ADL-P based platforms, this option is forced to be enabled as ADL-P FSP relies on MBP HOB for ChipsetInit version for ChipsetInit sync. Removed SoC specific implementation of `FSP_PUBLISH_MBP_HOB` config from MTL and TGL config file. TEST=Tested on ADL-P and ADL-N platforms. Verified that MBP HOB is created when `FSP_PUBLISH_MBP_HOB` is enabled and not created when it is disabled. Also verified that the system boots successfully in both cases.

Signing is performed with test keys by default, set CONFIG_SIGNING_KEYS_DIR to a non-empty value to use other keys. Depending on the version of the Talos II firmware this alone might not allow booting because coreboot replaces only part of the stock firmware and its newer versions enable secure boot by default (not to be confused with SecureBoot in EFI). The signing performed in this commit is still a prerequisite and might as well be done on its own. Fixing operation with newer stock firmware will be done in a follow-up change.

2024-09-02soc/intel/alderlake: Prevent overlapping boot screensSubrata Banik
Previously, `early_graphics_stop()` was skipped unconditionally if `CONFIG(SOC_INTEL_CSE_LITE_SYNC_IN_RAMSTAGE)` was enabled. This led to overlapping screens when CSE sync was not triggered in ramstage, as both the eSOL message and the firmware splash screen would be displayed. This change refactors the condition for calling `early_graphics_stop()` to ensure it is only skipped if a CSE firmware update is actually required *and* `CONFIG(SOC_INTEL_CSE_LITE_SYNC_IN_RAMSTAGE)` is set. This allows eSOL to display its message during CSE sync, but tears down early graphics programming in other cases to prevent overlapping screens. Additionally, this change ensures that `early_graphics_stop()` is the last function called by the romstage to guarantee proper cleanup.

This patch eliminates the LPC_IOE_COMA_EN and LPC_IOE_COMB_EN IO enables from the io_enables variable in the pch_early_iorange_init() function because lpc_io_setup_comm_a_b() is intended to activate legacy COM ports like COM-A (0x3F8 - 0x3FF) and COM_B (0x2F8 - 0x2FF).

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.

2024-08-22soc/intel/alderlake: Refactor eSOL for late CSE sync text messageSubrata Banik
This patch extends the eSOL implementation on Alder Lake to render text messages during late CSE sync (from ramstage). Currently, the eSOL is limited to the early boot phase (until romstage) and only displays FSP-M memory training warnings or messages during early CSE sync (at romstage). Platforms like Nissa/Nirul and Trulo, which use CSE sync from ramstage, cannot display any eSOL messages, resulting in a brief black screen during CSE firmware updates. This patch implements the following logic to scale eSOL for late CSE sync (at ramstage) without recompiling eSOL code for ramstage: 1. During boot, check if the MRC cache is available. This indicates the need for memory/DRAM training and triggers an eSOL message. 2. For CSE lite SKUs (applicable to CrOS), leverage the `is_cse_fw_update_required` API to check if the current CSE RW firmware version differs from the CBFS metadata file version.

2024-08-22soc/intel/alderlake: Preserve eSOL for late CSE syncSubrata Banik
This patch prevents the eSOL screen from being wiped out on Alder Lake platforms that use late CSE sync (from ramstage). This allows the eSOL text message to remain visible until ramstage. Currently, the eSOL only functions during the early boot phase (until romstage), so platforms like Nissa/Nirul and Trulo, which use CSE sync from ramstage, cannot display any eSOL messages to the user. A future patch will ensure the eSOL remains relevant for CSE sync in ramstage, but this patch is necessary to avoid tearing down the IGD text mode when exiting romstage. BUG=b:359814797 TEST=eSOL text mode is not torn down when exiting romstage.

This adds pmc_ipc to bootblock if SOC_INTEL_COMMON_BLOCK_PMC is enabled. The good place to report SoC QDF can be report_cpu_info in bootblock. QDF read is done by PMC IPC Command, so this adds pmc_ipc to bootblock to enable calling pmc_dump_soc_qdf_info.

2024-08-21soc/intel/common/block/cpu: Round up the number of waysJeremy Compostella
`CONFIG_DCACHE_RAM_SIZE' is not necessarily a multiple of way size. As a result, when the `div' instruction is called to compute the needed number of ways, there could be a remainder. When there is, one extra way should be added to cover `CONFIG_DCACHE_RAM_SIZE'.

2024-08-21soc/intel/common/block/cpu: Fix ways count computation regressionJeremy Compostella
Commit 16ab9bdcd578612bb3822373547f939eb90afd82 ("soc/intel/common: Calculate and configure SF Mask 2") breaks the computation of the number of ways and as result, all the derived masks. It results in MSR such as `IA32_L3_MASK_1' to be improperly programmed yielding unpredictable NEM issues such as hangs. Indeed, this commit has introduced a backup of 0x1 into %edx before comparing the requested cache-as-RAM size against the way size. When the requested cache-as-RAM is larger, it reaches the second part of the algorithm which computes the necessary number of ways to fit the requested cache-as-RAM. This algorithm uses the `div' instruction. Per specification, the div instruction divides the 64 bits combination of %edx and %eax register. Since 0x1 got backed up in %edx and assuming a `CONFIG_DCACHE_RAM_SIZE' of 0x200000, we end up dividing 0x100200000 by the way size instead of 0x200000 which result in a necessary number of ways of 4098 for a way size of 0x100000. This commit clears the %edx register before calling the `div' instruction.
