2021-05-07soc/intel/{adl,tgl,jsl}: Add smihandler_soc_disable_busmasterKane Chen
If a power button SMI is triggered between where it is currently enabled and before FSP-S exits, when the SMI handler disables bus mastering for all devices, it inadvertently also disables the PMC's I/O decoding, so the register write to actually go into S5 does not succeed, and the system hangs. This can be solved by skipping the PMC when disabling bus mastering in the SMI handler, for which a callback, smihandler_soc_disable_busmaster is provided.

2021-05-06soc/intel/tgl,mb/google/volteer: Add API for Type-C aux bias padsTim Wawrzynczak
TGL boards using the Type-C subsystem for USB Type-C ports without a retimer attached may require a DC bias on the aux lines for certain modes to work. This patch adds native coreboot support for programming the IOM to handle this DC bias via a simple devicetree setting. Previously a UPD was required to tell the FSP which GPIOs were used for the pullup and pulldown biases, but the API for this UPD was effectively undocumented. BUG=b:174116646 TEST=Verified on volteer2 that a Type-C flash drive is enumerated succesfully on all ports.

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.

2021-04-22soc/intel/alderlake and mb: Drop PchHdaAudioLink*Enable UPDs from chip.hFurquan Shaikh
FSP uses PchHdaAudioLink{Hda|Dmic|Ssp|Sndw}Enable UPDs to configure GPIO pads for audio. However, mainboard is expected to perform all GPIO configration in coreboot and hence these UPDs must be set to 0. There is no need to expose these UPDs in chip.h and provide mainboard an option to set these in devicetree. This change drops PchHdaAudioLink{Hda|Dmic|Ssp|Sndw}Enable UPDs from chip.h and the corresponding devicetree in mainboards. Currently, shadowmountain already set these UPDs to 0, whereas adlrvp set these to 1.

We had the addrspace_32bit rdev in prog_loaders.c for a while to help represent memory ranges as an rdev, and we've found it useful for a couple of things that have nothing to do with program loading. This patch moves the concept straight into commonlib/region.c so it is no longer anchored in such a weird place, and easier to use in unit tests. Also expand the concept to the whole address space (there's no real need to restrict it to 32 bits in 64-bit environments) and introduce an rdev_chain_mem() helper function to make it a bit easier to use.

2021-04-18soc/intel/cnl and mainboards: Drop `cnl_configure_pads()`Furquan Shaikh
CB:31250 ("soc/intel/cannonlake: Configure GPIOs again after FSP-S is done") introduced a workaround in coreboot for `soc/intel/cannonlake` platforms to save and restore GPIO configuration performed by mainboard across call to FSP Silicon Init (FSP-S). This workaround was required because FSP-S was configuring GPIOs differently than mainboard resulting in boot and runtime issues because of misconfigured GPIOs. This issue has since been fixed in FSP (verified with FSP v1263 on hatch). However, there were still 4 boards in coreboot using `cnl_configure_pads()`. As part of RFC CB:50829, librem_cnl, clevo/cml-u and system76/lemp9 were tested to ensure that this workaround is no longer required. This change drops the workaround using `cnl_configure_pads()` and updates all mainboards to use `gpio_configure_pads()` instead.

2021-04-06intel/tigerlake: Add Acoustic featuresShaunak Saha
On VCCin there was an oscillation which occurred just as the kernel started (kernel starting... message). On some devices, this behavior seems even worse. In previous platforms VCCin toggled for a few ms and then was stable. For volteer, this happens at the same point in time for around 40ms. However, it starts oscillating again later in the boot sequence. Once at the root shell, it seems to oscillate indefinitely at around 100-200Hz (very variable though). To fix this we need to control the deep C-state voltage slew rate.We have options for controlling the deep C-state voltage slew rate through FSP UPDs. This patch expose the following FSP UPD interface into coreboot: - AcousticNoiseMitigation - FastPkgCRampDisable - SlowSlewRate We are setting SlowSlewRate for all volteer boards to 2 which is Fast/8. TGL has a single VR domain(Vccin). Hence, the chip config is updated to allow mainboards to set a single value instead of an array and FSP UPDs are accordingly set.

2021-04-06soc/intel/common: Prevent SMI storm when setting SPI WPD bitAngel Pons
From Skylake/Sunrise Point onwards, there are two BIOS_CNTL registers: one on the LPC/eSPI PCI device, and another on the SPI PCI device. When the WPD bit changes from 0 to 1 and the LE bit is set, the PCH raises a TCO SMI with the BIOSWR_STS bit set. However, the BIOSWR_STS bit is not set when the TCO SMI comes from the SPI or eSPI controller instead, but a status bit in the BIOS_CNTL register gets set. If the SMI cause is not handled, another SMI will happen immediately after returning from the SMI handler, which results in a deadlock. Prevent deadlocks by clearing the SPI synchronous SMI status bit in the SMI handler. When SPI raises a synchronous SMI, the TCO_STS bit in the SMI_STS register is continously set until the SPI synchronous SMI status bit is cleared. To not risk missing any other TCO SMIs, do not clear the TCO_STS bit again in the same SMI handler invocation. If the TCO_STS bit remains set when returning from SMM, another SMI immediately happens and clears the TCO_STS bit, handling any pending events. SPI can also generate asynchronous SMIs when the WPD bit is cleared and one attempts to write to flash using SPI hardware sequencing. This patch does not account for SPI asynchronous SMIs, because they are disabled by default and cannot be enabled once the BIOS Interface Lock-Down bit in the BIOS_CNTL register has been set, which coreboot already does. These asynchronous SMIs set the SPI_STS bit of the SMI_STS register. Clearing the SPI asynchronous SMI source should be done inside the SPI_STS SMI handler, which is currently not implemented. All of this goes out of the scope of this patch, and is currently not necessary anyway. This patch does not handle eSPI because I cannot test it, and knowing if a board uses LPC or eSPI from common code is currently not possible, and this is beyond the scope of what this commit tries to achieve (fix SPI). Tested on HP 280 G2, no longer deadlocks when SMM BIOS write protection is on. Write protection will be enforced in a follow-up.
