2020-07-03soc/intel/tigerlake: Disable hybrid storage mode in CSE Lite RO bootJamie Ryu
A UPD HybridStorageMode allows a platform to dynamically configure the PCIe strap configuration required if an Optane device is connected. The strap configuration is done by HECI commands between FSP and CSE to override the default PCIe strap value, and the updated strap value is stored in SPI RW data to be used on the next boot. CSE Lite supports the strap override when running on CSE RW partition, while CSE RO partition does not support it because CSE RO is not allowed to access SPI RW data. The strap override failure on CSE RO causes FSP not initializing PCH Clkreq and PCIe port mapping and this results NVMe and Optane initialization failure. By disabling HybridStorageMode in case of CSE RO boot, NVMe detection is done by the default PCIe configuration and Optane is detected as a single NVMe storage device on CSE RO boot in recovery mode. Both NVMe and Optane devices detection as well as OS installation to these storage devices are verified on CSE RO boot in recovery mode.

Therefore, all active high (edge or level) virtual wire interrupts need to ensure they are not inverted. And really the sender of the interrupts should be conforming to the the eSPI spec.

The ACPI code was not masking off the correct bits for publishing the SPI bar to the OS. It resulted in a dmesg messagelike: system 00:00: [mem 0xfec10002-0xfec11001] has been reserved And /proc/iomem entry fec10002-fec11001 : pnp 00:00 These addresses are wrong because they are including bits of a register that are not a part of the address. Moreover, the code does not publish the eSPI register area either. The eSPI registers live at 0x10000 added to the SPI bar. Lastly, both regions are less than a page so only report a page of usage for each. Stoney Ridge's SPI bar register defines the address as 31:6 while Picasso's SPI bar register defines the address as 31:8. Use Picasso's valid mask for both cases because no one is assigning addresses that are aligned to less than 256 bytes.

2020-06-30soc/amd/gpio, mb/{amd,google}: Configure pads using a single entry in GPIO ↵Furquan Shaikh
configuration table Currently, for Stoneyridge and Picasso mainboards, pads that are configured for SCI/SMI/WAKE need to have multiple entries in the configuration table - one for PAD_GPI and other for the special configuration that is required. This requires a very specific ordering of pads within the table and is prone to errors because of conflicting params provided to the different entries for the same pad. This also does not work very well with the concept of override GPIOs where the entry in base table is overridden with the first matched entry from the override table. This change updates the way GPIO configuration is handled for special routing like SCI/SMI/WAKE/DEBOUNCE by setting the control field of soc_amd_gpio structure in the macros performing these configurations. Also, program_gpios() is updated to perform a write to GPIO control register instead of read-modify-write. This is because mainboard is expected to provide only a single configuration entry for each pad within a given table. Thus, there is no need to preserve earlier configuration. Mainboards that were providing multiple entries for a single pad are updated accordingly.

The previous Intel CPX-SP FSP release was ww20 release. The ww22 release fixs issues related to FSP_NV_STORAGE HOB. The end of end flow of using memory training data to generate FSP_NV_STORAGE HOB and using memory training data passed from bootloader to skip memory training, works now. This saves 8 minutes of boot time (with FSP verbose logging enabled on DeltaLake server). This release also adds UPD parameters to support IIO bifuration. The ww24 release has following updates: a. Removed a number of unnecessary UPD parameters, such as mmiolSize, mmiolBase, OemHookPostTopologyDiscovery, OemGetResourceMapUpdate. b. Added UPD parameters to support PCIe ports configuration. c. Updated IIO_UNIVERSAL_DATA HOB, each stack now has mmio base/limit fields, in addition to PCIe resource memory base/limit fields. With ww24 release, the issue with PCIe link training persists. On YV3 config A, the onboard NIC card has x4 connection to port 2D. This NIC device is not recognized by FSP. Corresponding soc/intel/xeon_sp/cpx change is made: * There are changes in PLATFORM_DATA structure, so hob_display.c is updated. * There are changes in UPD parameters, so romstage.c is updated.

2020-06-25Revert "soc/amd/common/block/acpimmio: Update acpimmio for psp_verstage"Kyösti Mälkki
This reverts commit 4883252912665f56c8e7801fe03a26594a1e9d5d. Almost everything in <amdblocks/acpimmio_map.h> is invalid for PSP as it does not have the same view of memory space. The prototypes xx_set/get_bar() are only valid for PSP as x86 cores will use the constant mapping defined in <amdblocks/acpimmio_map.h> The selected MMIO base address model depends of the architecture the stage is built for and, to current knowledge, nothing else. So the guards should have been with ENV_X86 vs ENV_ARM and not about CONFIG(VERSTAGE_BEFORE_BOOTBLOCK). For the ENV_ARM stage builds, <arch/io.h> file referenced in the previously added mmio_util_psp.c file has not been added to the tree. So there was some out-of-order submitting, which did not get caught as the build-testing of mixed-arch stages has not been incorporated into the tree yet. The previously added file mmio_util_psp.c is also 90% redundant with mmio_util.c.
