2023-06-23soc/intel/alderlake/hsphy: Add possibility to cache HSPHY in flashMichał Żygowski
The patch adds a possibility to cache the PCIe 5.0 HSPHY firmware in the SPI flash. New flashmap region is created for that purpose. The goal of caching is to reduce the dependency on CSME and the HECI IP LOAD command which may fail when the CSME is disabled, e.g. soft disabled by HECI command or HAP disabled. This change allows to keep PCIe 5.0 root ports functioning even if CSME/HECI is not functional. TEST=Boot Ubuntu 22.04 on MSI PRO Z690-A and notice PCIe 5.0 port is functional after loading the HSPHY from cache.

2023-03-17soc/intel/alderlake/hsphy.c: Handle case with DMA protectionMichał Żygowski
The HSPHY firmware must be downloaded to DMA-allowed host address space. Check for DMA buffer presence and use it as the buffer for HSPHY firmware to be downloaded from CSME. TEST=Successfully load HSPHY firmware to CPU on MSI PRO Z690-A DDR4 with DMA protection enabled.

2022-09-02cbfs/vboot: Adapt to new vb2_digest APIJulius Werner
CL:3825558 changes all vb2_digest and vb2_hash functions to take a new hwcrypto_allowed argument, to potentially let them try to call the vb2ex_hwcrypto API for hash calculation. This change will open hardware crypto acceleration up to all hash calculations in coreboot (most notably CBFS verification). As part of this change, the vb2_digest_buffer() function has been removed, so replace existing instances in coreboot with the newer vb2_hash_calculate() API. Due to the circular dependency of these changes with vboot, this patch also needs to update the vboot submodule: Updating from commit id 18cb85b5: 2load_kernel.c: Expose load kernel as vb2_api to commit id b827ddb9: tests: Ensure auxfw sync runs after EC sync This brings in 15 new commits.

2022-08-24soc/intel/alderlake/hsphy: Add support for HSPHY firmware loadingMichał Żygowski
BIOS must send the IP_LOAD HECI command to fetch the firmware for CPU PCIe Gen5 and upload it via CPU REG BAR prior FSP Silicon Init. Implementation based on public Slimbootloader's "Silicon/AlderlakePkg/Library/CpuPcieHsPhyInitLib". TEST=Boot MSI PRO Z690-A and see the HSPHY FW is loaded. PCIe x16 Gen3 GPU card started working in the PCIE 5.0 slot. [DEBUG] HECI: Sending Get IP firmware command [DEBUG] HECI: Get IP firmware success.
