2021-01-11acpi,soc/intel/common: add support for Intel Low Power Idle TableMichael Niewöhner
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.

2021-01-11{soc,vc,mb}/intel: Drop support for Cannon Lake SoCFelix Singer
Drop the support for the Intel Cannon Lake SoC for various reasons: * Most people can't use coreboot on Cannon Lake, since the required FSP binaries aren't publicly available. Given that FSP binaries for several newer platforms have been released, it's very unlikely that Cannon Lake FSP will ever be released. * It seems there is no interest in this, since the reference mainboard is the only available mainboard in tree. 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.

This change renames `struct uart_gpio_pad_config` to `struct uart_controller_config` and adds a new parameter devfn (which expects devfn for the UART controller corresponding to the index in PCI_DEVFN() format). This gets rid of the SoC callback to get `struct device` pointer to the UART controller device.

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).

2020-12-22soc/intel/common/block/acpi: Fix get_cores_per_packagePatrick Rudolph
Current implementation uses CPUID 0Bh function that returns the number of logical cores of requested level. The problem with this approach is that this value doesn't change when HyperThreading is disabled (it's in the Intel docs), so it breaks generate_cpu_entries() because `numcpus` ends up being zero due to integer division truncation. - Use MSR 0x35 instead, which returns the correct number of logical processors with and without HT. - Use cpu_read_topology() to gather the required information Tested on Prodrive Hermes, the ACPI code is now generated even with HyperThreading disabled.
