2021-04-26soc/intel/elkhartlake: Update GPIO communitiesTan, Lean Sheng
GPIOs are divided into different communities. Each community consists of one or more GPIO groups. We need to configure the groups in coreboot so that they are mapped properly. GPIO communities should be properly configured in GPIO_CFG and MISCCFG registers. GPP_* defines in gpio_soc_defs.h are configured in GPIO_CFG register while the PMC_GPP_* in pmc.h. GPIO communities in coreboot should match with the kernel gpio communities also. Kernel reads the ASL file from coreboot. This patch adds the proper community mapping in ASL code to match with kernel code. In gpio_soc_defs.c file we are indexing the groups correctly. In gpio.h file we define all the gpio devices as kernel populates sysfs with separate gpio device for each community. This patch is created based on Intel EHL PCH Datasheet with Document number 614109 and Chapter 21. Also update GPIO COM3 Port ID and 2 GPIO register values (HOSTSW_OWN_REG_0 & PAD_CFG_BASE) respectively.

CONFIG_MAX_PCIE_CLOCKS renamed to MAX_PCIE_CLOCK_SRC to make it clear that this config is for the number of PCIe Clock sources available which is different from PCIe clock reqs. This is more relevant in alderlake, as the number clock source and clock reqs differ. However since this is a better name, renaming it throughout the soc/intel tree.

Commit 2c26108208e4aa48de21be576ab6cad9286d7934 moved this function to pmutil.c for Tiger Lake. Do this to all other platforms for consistency. For Skylake, __SIMPLE_DEVICE__ preprocessor guards are no longer needed. With this change, pmc.c is only needed in ramstage. Adjust Makefile.inc accordingly, and drop ENV_RAMSTAGE guards from Skylake.

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. Without this CL : GPIO COMM 0 MISCCFG:0xC0 (Bit 6 and 7 enable) With this CL : GPIO COMM 0 MISCCFG: 0x00 (Bit 6 and 7 disable) Change-Id: Ie027cbd7b99b39752941384339a34f8995c10c94 Signed-off-by: Subrata Banik <subrata.banik@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/51767 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>

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.)

2021-03-03soc/intel: Backport SMRR locking supportAngel Pons
Backport commit 0cded1f116 (soc/intel/tigerlake: Add SMRR Locking support) to other client platforms. The SMRR MSRs are core-scoped on Skylake and Ice Lake, at least. Older platforms do not support SMRR locking, but now there's seven copies of the same file in the tree. A follow-up will deduplicate smmrelocate.c files into common CPU code. I cannot test Jasper Lake nor Elkhart Lake, but they should still work. As per documentation I do not have access to, Elkhart Lake seems to support SMRR locking. However, Jasper Lake documentation is unclear. Tested on Purism Librem Mini v1 (WHL-U i7-8565U), still boots and SMRR MSRs have the same value on all cores/threads (i7-8565U supports HT).

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.

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.

This change drops the parameter `struct device *dev` from the function `soc_get_gen_io_dec_range()`. This function uses the parameter dev to get a pointer to config structure for extracting the decode ranges configured by mainboard in device tree. However, there is no separate chip driver for the LPC device which means that the SoC code can use `config_of_soc()` to get to SoC chip config instead of using the LPC device. This change is being done in preparation to clean up the device tree/chip config access in early stages that allows for optimizing the inclusion of device tree elements in the early stages.

2020-10-28soc/intel: deduplicate ACPI timer emulationMichael Niewöhner
The code for enabling ACPI timer emulation is the same for the SoCs SKL, CNL, ICL, TGL, JSL and EHL. Deduplicate it by moving it to common code. APL differs in not having the delay settings. However, the bits are marked as "spare" and BWG mentions there are no "reserved bit checks done". Thus, we can write them unconditionally without any effect. Note: The ACPI timer emulation can only be used by SoCs with microcode supporting CTC (Common Timer Copy) / ACPI timer emulation.

2020-10-26soc/intel: drop unneeded ISST configuration codeMichael Niewöhner
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. Test: Linux on Supermicro X11SSM-F detects and enables HWP: [ 0.415017] intel_pstate: HWP enabled Change-Id: I952720cf1de78b00b1bf749f10e9c0acd6ecb6b7 Signed-off-by: Michael Niewöhner <foss@mniewoehner.de> Reviewed-on: https://review.coreboot.org/c/coreboot/+/46460 Reviewed-by: Nico Huber <nico.h@gmx.de> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Reviewed-by: Felix Singer <felixsinger@posteo.net> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
