2021-06-23soc/intel/jasperlake: Use devfn_disable() function for XDCISubrata Banik
Use devfn_disable() for disabling a PCI device rather than using `dev->enabled = 0`. Also, use is_devfn_enabled() to get the device current state prior updating the FSP-S UPD for XDCI. TEST=FSP-S disabled XDCI when `xdci_can_enable` returns 0 and XDCI is disabled at PCI enumeration `PCI: 00:14.1: enabled 0`.

With the recent switch to SMM module loader v2, the size of the SMM for module google/volteer increased to above 64K in size, and thus failed to install the permanent SMM handler. Turns out, the devicetree is all pulled into the SMM build because of elog, which calls `pci_dev_is_wake_source`, and is the only user of `struct device` in SMM. Changing this function to take a pci_devfn_t instead allows the linker to remove almost the entire devicetree from SMM (only usage left is when disabling HECI via SMM).

2021-03-27soc/intel: Rename and move MISCCFG_GPIO_PM_CONFIG_BITS definition to soc/gpio.hSubrata Banik
Lists of changes: 1. Rename MISCCFG_ENABLE_GPIO_PM_CONFIG -> MISCCFG_GPIO_PM_CONFIG_BITS 2. Move MISCCFG_GPIO_PM_CONFIG_BITS definition from intelblock/gpio.h to soc/gpio.h. Refer to detailed description below to understand the motivation behind this change. An advanced GPIO PM capabilities has been introduced since CNP PCH, refer to 'include/intelblock/gpio.h' for detailed GPIO PM bit definitions. Now with TGP PCH, additional bits are defined in the MISCCFG register for GPIO PM control. This results in different SoCs supporting different number of bits. The bits defined in earlier platforms (CNL, CML, ICL) are present on TGL, JSL and ADL too. Hence, refactor the common GPIO code to keep the bit definitions in intelblock/gpio.h, but the definition of MISCCFG_GPIO_PM_CONFIG_BITS is moved to soc/gpio.h so that each SoC can provide this as per hardware support. TEST=On ADL, TGL and JSL platform.

2021-03-17spd_bin: Replace get_spd_cbfs_rdev() with spd_cbfs_map()Julius Werner
In pursuit of the goal of eliminating the proliferation of raw region devices to represent CBFS files outside of the CBFS core code, this patch removes the get_spd_cbfs_rdev() API and instead replaces it with spd_cbfs_map() which will find and map the SPD file in one go and return a pointer to the relevant section. (This makes it impossible to unmap the mapping again, which all but one of the users didn't bother to do anyway since the API is only used on platforms with memory-mapped flash. Presumably this will stay that way in the future so this is not something worth worrying about.)

2021-01-31soc/intel/*: drop incomplete and unneeded check for DMI SRLOCKMichael Niewöhner
Before enabling IO decode ranges, current code checks if the DMI SRLOCK is set to prevent inconsistencies between LPC PCI cfg registers and LPC DMI registers, when the latter are locked. DMI SRLOCK only applies to PCHs with on-package DMI, but not to PCH-H, PCH-S and others with discrete PCH packages. So this check is at least incomplete. Further, the lock gets applied by FSP and gets reset on a warm reset. Thus, there is no case where the lock would be already set at the places where the DMI registers get written currently. Drop the checks for the reasons mentioned above.

This function uses the parameter dev to get a pointer to config structure for extracting the decode ranges configured by mainboard in device tree.

2020-11-09soc/intel/jasperlake: Correct GPIO pad sequence for community pad groupMaulik V Vaghela
In gpio.c file, we have community group array for each comm, representing gpio groups within that community. Like there might be group H,D, VGPIO and C within community 1. Community also may have some reserved gpio and we also define those in an array which indicates OS can't use those GPIO (through PAD_BASE_NONE) Now when we define reserved pads in the middle of actual community pads, it creates an issue while calculating an offset for GPIO host own pad register. This is because function actually checks current gpio index (lets say vgpio_39 in our case) and tries to get group index from an array which we have defined. If we have defined reserved gpios in between 2 communities, index calculated will also account for reserved GPIO and register offset calculation will move to next set of register (offset 0xC instead of offset 0x8). Because of this coreboot won't configure HOST_OWN_PAD register correctly and driver will not be able to get non-SMI interrupts for related gpio. Align pad group as per EDS and pin-ctrl driver in linux kernel. Reference: DOC#618876 (EDS volume 2) BUG=None BRANCH=None TEST=VGPIO community index is correctly calculated.

The code configuring ISST (Intel SpeedShift Technology) sets the ISST capability bits in CPUID.06H:EAX. It does *not* activate HWP (Hardware P-States), which shall be done by the OS only. Since the capability is enabled by default (opt-out), there is nothing to do for us in the enabled-case. Practically speaking, there is no value at all in disabling the capability, since one can configure the OS to not enable HWP if that is desired. The two other bits for EPP and HWP interrupt that were set by the code are not set anymore, too. It was tested, on three platforms so far (CML-U, KBL-H, SKL-U), that these are set as well by default in the MSRs reset value (0x1cc0). To reduce complexity and duplicated code without actual benefit, this code gets dropped. The remaining dt option will be dropped in CB:46462.
