2021-01-25soc/intel/{skl,cnl,xsp,icl,tgl,ehl,adl,jsl}: use common LPC mirroringMichael Niewöhner
Drop the old, redundant code for mirroring LPC registers to DMI and make use of the new common code. Select the new Kconfig option for LPC DMI mirroring by the option SOC_INTEL_COMMON_PCH_BASE, which is selected by platforms starting with SPT, except APL and Xeon-SP. For Xeon-SP, select DMI and the new Kconfig directly. APL, even though it's younger than SPT, does not need mirroring. Test: Set LGMR address by calling `lpc_open_mmio_window` and check that both the PCI cfg and DMI LGMR register get written correctly. Tested successfully on clevo/cml-u.

2021-01-25soc/intel/lpc_lib: mirror LPC registers to DMI when requiredMichael Niewöhner
Starting with SPT, LPC registers IOD, IOE, LGIR* and LGMR need to be mirrored to their corresponding DMI registers. Add the required writes to DMI registers, where the PCI config registers get written. This is already done in soc code for IOD, IOE and LGIR* by mirroring the registers later, during PCH init. Also the code mostly matches accross the platforms. This common implementation will avoid delayed mirroring of the registers and also deduplicate the code. This change also adds a new Kconfig that will be selected by platforms requiring mirroring of LPC IO/MMIO registers to their corresponding DMI registers. For making use of this common code, the redundant soc code needs to be dropped and the newly introduced Kconfig option has to be selected. This is done in the follow-up change.

2021-01-25soc/intel/common: Add support for populating meminit dataFurquan Shaikh
This change adds support for a common block memory driver that can be used for performing the required operations to read SPD data for different memory channel DIMMs. This data can then be used by the SoC code to populate different memory related UPDs. Most recent Intel platforms follow a similar pattern for configuring FSP-M UPDs for initializing memory. These platforms use one of the following topologies: 1. Memory down 2. DIMM modules 3. Mixed Thus, SPD data is either obtained from CBFS (for memory down topology) or from on-module EEPROM (for DIMM modules). This SPD data read from CBFS or EEPROM is then passed into FSP-M using SPD UPDs for different channels/DIMMs as per the memory organization. Similarly, DQ/DQS configuration is accepted from mainboard and passed into FSP-M using UPDs as per the FSP-M/MRC organization of memory channels. Different memory technologies on a platform support physical channels of different widths. Since the data bus width is fixed for a platform, the number of physical channels is determined by data bus width / physical channel width. The number of physical channels are different depending upon the size of physical channel supported by the memory technology. FSP-M for a platform uses the same set of UPDs for different memory technologies and aims at providing maximum flexibility. Thus, the platform code needs to format mainboard inputs for DQ, DQS and SPD into the UPDs appropriately as per the memory technology used by the board. Example: DDR4 on TGL supports 2 physical channels each 64-bit wide. However, FSP-M UPDs assume channels 16-bit wide. Thus, FSP-M provides 16 UPDs for SPDs (considering 2 DIMMs per channel and 8 channels with each channel 16-bit wide). Hence, for DDR4, only the SPD UPDs for MRC channel 0 and 4 are supposed to be used. This common driver allows the SoC to define the attributes of the platform: 1. DIMMS_PER_CHANNEL: Maximum DIMMs that are supported per channel by any memory technology on the platform 2. DATA_BUS_WIDTH: Width of the data bus. 3. MRC_CHANNEL_WIDTH: Width of the channel as used by the MRC to define UPDs. In addition to this, the SoC can define different attributes of each memory technology supported by the platform using `struct soc_mem_cfg`: 1. Number of physical channels 2. Physical channel to MRC channel mapping 3. Masks for memory down topologies Using the above information about different memory technologies supported by the platform and the mainboard configuration for SPD, the common block memory driver reads SPD data and provides pointers to this data for each dimm within each channel back to the SoC code. SoC code can then use this information to configure FSP-M UPDs accordingly. In addition to that, the common block driver also returns information about how the channels are populated so that the SoC code can use this information to expose DQ/DQS information in FSP-M UPDs. This driver aims at minimizing the effort required for supporting different memory technologies on any new Intel SoC by reducing per-SoC effort to a table of configurations rather than having to implement similar logic for each SoC.

The code for setting the LPC generic memory range uses an array of fixed address ranges not needing explicit decoding, to decide if the address needs to be written to the LGMR register. Most platforms only mistakenly add the PCH reserved mmio range, that is not decoded generally, effectively breaking the mechanism. Only APL uses the array correctly. That code, in it's current state, does not work (except for APL) and currently, there is not a single user. Thus, drop it before people start using it.

2021-01-18soc/intel/common/pcie: Allow pcie_rp_group table to be non-contiguousFurquan Shaikh
In case of CPU PCIe RPs, the RP numbers might not be contiguous for all the functions in a slot. Example: In ADL, RP1 is 00:06.0, RP2 is 00:01.0 and RP3 is 00:06.2 as per the FSP expectations. Hence, this change updates the defintion of `struct pcie_rp_group` to include a `start` member which indicates the starting PCI function number within the group. All common functions for PCIe RP are accordingly updated to take the `start` member into account. Thus, in the above example, ADL can provide a cpu_rp_table as follows: { { .slot = PCIE_SLOT_6, .start = 0, .count = 1 }, { .slot = PCIE_SLOT_1, .start = 0, .count = 1 }, { .slot = PCIE_SLOT_6, .start = 2, .count = 1 }, } Since start defaults to 0 when uninitialized, current PCH RP group tables don't need to be updated.

2021-01-15cpu/x86/mpinit: Serialize microcode updates for HT threadsPatrick Rudolph
This change affects Intel CPUs only. As most platforms are doing uCode update using FIT, they aren't affected by this code either. Update microcode in MP-init using a single spinlock when running on a Hyper-Threading enabled CPU on pre FIT platforms. This will slow down the MP-init boot flow. Intel SDM and various BWGs specify to use a semaphore to update microcode on one thread per core on Hyper-Threading enabled CPUs. Due to this complex code would be necessary to determine the core #ID, initializing and picking the right semaphore out of CONFIG_MAX_CPUS / 2. Instead use the existing global spinlock already present in MPinit code. Assuming that only pre-FIT platforms with Hyper-Threading enabled and at most 8 threads will ever run into this condition, the boot delay is negligible. This change is a counterproposal to the previous published patch series being much more unsophisticated.

Add support for the Intel LPIT table to support reading Low Power Idle Residency counters by the OS. On platforms supporting S0ix sleep states there can be two types of residencies: * CPU package PC10 residency counter (read from MSR via FFH interface) * PCH SLP_S0 assertion residency counter (read via memory mapped interface) With presence of one or both of these counters in the LPIT table, Linux dynamically adds the corresponding attributes to the cpuidle sysfs interface, that can be used to read the residency timers: * /sys/devices/system/cpu/cpuidle/low_power_idle_cpu_residency_us * /sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us The code in src/acpi implements generic LPIT support. Each SoC or platform has to implement `acpi_fill_lpit` to fill the table with platform-specific LPI state entries. This is done in this change for soc/intel/common, while being added as its own compilation unit, so SoCs not yet using common acpi code (like Skylake) can use it, too.

Also, remove the related reference mainboard intel/cannonlake_rvp and its FSP headers in intel/fsp2_0/cannonlake.

2021-01-11soc/intel/common/uart: Use simple(_s_) variants of PCI functionsFurquan Shaikh
This change updates various uart_* functions to use simple(_s_) variants of PCI functions. This is done for a few reasons: * __SIMPLE_DEVICE__ check can be dropped since the same data type can be used in early stages and ramstage. * Removes the requirement on early stage to walk the device tree to get access to the device structure. This allows linker-based device tree optimizations for early stages. As part of this change, uart_get_device() is refactored and a new function uart_console_get_devfn() is added which returns pci_devfn_t in MMCONF format. It is then used directly by the _s_ variants of PCI functions.

2021-01-11soc/intel/cnl: Allow setting PCIe subsystem IDs after FSP-SJeremy Soller
Prevent the FSP from writing its default SVID SDID values of 8086:7270 for internal devices as this locks most of the registers. Allows the subsystemid values set in devicetree to be used. A description of this SSID table override behavior, along with example code, is provided in the TigerLake FSP Integration Guide, section 15.178 ("SI_CONFIG Struct Reference"). The xHCI and HDA devices have RW/L registers rather than RW/O registers. They can be written to multiple times but cannot be modified after being locked, which happens during FspSiliconInit. Because coreboot populates subsystem IDs after SiliconInit, these devices specifically must be written beforehand or will otherwise be locked with their default values of 0:0. Tested by checking lspci output on System76 galp3-c (WHL), oryp5 (CFL), and oryp6 (CML).
