2021-04-21commonlib/region: Turn addrspace_32bit into a more official APIJulius Werner
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. Replace some direct uses of struct mem_region_device with this new API where it seems to make sense.

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.

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.

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.)

2021-03-16cbfs: Remove prog_locate() for stages and rmodulesJulius Werner
This patch removes the prog_locate() step for stages and rmodules. Instead, the stage and rmodule loading functions will now perform the locate step directly together with the actual loading. The long-term goal of this is to eliminate prog_locate() (and the rdev member in struct prog that it fills) completely in order to make CBFS verification code safer and its security guarantees easier to follow. prog_locate() is the main remaining use case where a raw rdev of CBFS file data "leaks" out of cbfs.c into other code, and that other code needs to manually make sure that the contents of the rdev get verified during loading. By eliminating this step and moving all code that directly deals with file data into cbfs.c, we can concentrate the code that needs to worry about file data hashing (and needs access to cbfs_private.h APIs) into one file, making it easier to keep track of and reason about. This patch is the first step of this move, later patches will do the same for SELFs and other program types.

2021-03-15pciexp_device: Rewrite LTR configurationNico Huber
I was bugged by spurious "Failed to enable LTR" messages for years. Looking at the the current algorithm, it is flawed in multiple ways: * It looks like the author didn't know they implemented a recursive algorithm (pciexp_enable_ltr()) inside another recursive algorithm (pciexp_scan_bridge()). Thus, at every tree level, everything is run again for the whole sub- tree. * LTR is enabled no matter if `.set_ltr_max_latencies` is implemented or not. Leaving the endpoints' LTR settings at 0: They are told to always report zero tolerance. In theory, depending on the root-complex implementation, this may result in higher power consumption than without LTR messages. * `.set_ltr_max_latencies` is only considered for the direct parent of a device. Thus, even with it implemented, an endpoint below a (non-root) bridge may suffer from the 0 settings as described above. * Due to the double-recursive nature, LTR is enabled starting with the endpoints, then moving up the tree, while the PCIe spec tells us to do it in the exact opposite order. With the current implementation of pciexp_scan_bridge(), it is hard to hook anything in that runs for each device from top to bottom. So the proposed solution still adds some redundancy: First, for every device that uses pciexp_scan_bus(), we enable LTR if possible (see below). Then, when returning from the bus- scanning recursion, we enable LTR for every device and configure the maximum latencies (if supported). The latter runs again on all bridges, because it's hard to know if pciexp_scan_bus() was used for them. When to enable LTR: * For all devices that implement `.set_ltr_max_latencies`. * For all devices below a bridge that has it enabled already.

2021-03-13soc/intel/common/fast_spi: Fix check-fmap-16mib-crossing checkFurquan Shaikh
Currently, `check-fmap-16mib-crossing` compares the offset and end of each SPI flash region to 16MiB to ensure that no region is placed across this 16MiB boundary from the start of SPI flash. What really needs to be checked is that the region isn't placed across the 16MiB boundary from the end of BIOS region. Thus, current check works only if the SPI flash is 32MiB under the assumption that the BIOS region is mapped at the top of SPI flash. However, this check will not work if a flash part greater than 32MiB is used. This change replaces the hardcoded boundary value of 16MiB with a value calculated by subtracting 16MiB from the SPI flash size (if it is greater than 16MiB). This calculated value is used as the boundary that no region defined in the flashmap should be placed across. The assumption here is that BIOS region is always placed at the top of SPI flash. Hence, the standard decode window would be from end_of_flash - 16M to end_of_flash (because end_of_flash = end_of_bios_region). Currently, there is no consistency in the name used for BIOS region in flashmap layout for boards in coreboot. But all Intel-based boards (except APL and GLK) place BIOS region at the end of SPI flash. Since APL and GLK do not support the extended window, this check does not matter for these platforms.

To make the end of the variable name clear, use braces, e.g. "${x}". NB. Most of the double quotes are unnecessary. They only change the way the script would be failing in case of spurious whitespace. * Break some lines doing multiple things at once. * To reduce remaining clutter, put reading numbers into a shell function. And functional changes: * No need to spawn `cat`, the shell can redirect input as well as output (using `<`). * To read a number from the `fmap_config.h`, we spawned 4 processes where a single one can achieve the same. With one exception: GNU awk refuses to parse hex numbers by default. Luckily, it turned out that we don't need intermediate decimal numbers: Shells can do arithmetic with hex values as well.

All the PMC functions used in early_tcss driver return some kind of response. These should be checked to return appropriate response code back to the caller. However, this needs to be done as a separate change.
