2020-12-08soc/intel/common/fast_spi: Add extended decode window supportSrinidhi N Kaushik
This change enables support for configuration of extended BIOS region decode window. This configuration needs to be performed as early as possible in the boot flow. This is required to ensure that any access to the SPI flash region below 16MiB in coreboot is decoded correctly. The configuration for the extended BIOS window if required is done as part of fast_spi_early_init(). Changes include: 1. Make a call to fast_spi_enable_ext_bios() before the bus master and memory space is enabled for the fast SPI controller. 2. Added a helper function fast_spi_enable_ext_bios() which calls fast_spi_get_ext_bios_window() to get details about the extended BIOS window from the boot media map. 3. Depending upon the SPI flash device used by the mainboard and the size of the BIOS region in the flashmap, this function will have to perform this additional configuration only if the BIOS region is greater than 16MiB 4.

2020-12-08coreboot tables: Add SPI flash memory map windows to coreboot tablesFurquan Shaikh
This change adds details about the memory map windows to translate addresses between SPI flash space and host address space to coreboot tables. This is useful for payloads to setup the translation using the decode windows already known to coreboot. Until now, there was a single decode window at the top of 4G used by all x86 platforms. However, going forward, platforms might support more decode windows and hence in order to avoid duplication in payloads this information is filled in coreboot tables. `lb_spi_flash()` is updated to fill in the details about these windows by making a call to `spi_flash_get_mmap_windows()` which is implemented by the driver providing the boot media mapping device.

2020-12-08soc/intel/common/fast_spi: Add custom boot media deviceFurquan Shaikh
This change enables support for a custom boot media device in fast SPI controller driver if the platform supports additional decode window for mapping BIOS regions greater than 16MiB. Following new Kconfigs are added: 1. FAST_SPI_SUPPORTS_EXT_BIOS_WINDOW: SoC can select this to indicate support for extended BIOS window. 2. EXT_BIOS_WIN_BASE: If FAST_SPI_SUPPORTS_EXT_BIOS_WINDOW is selected, this provides the base address of the host space that is reserved for mapping the extended window. 3. EXT_BIOS_WIN_SIZE: If FAST_SPI_SUPPORTS_EXT_BIOS_WINDOW is selected, this provides the size of the host space reserved for mapping extended window. If platform indicates support for extended BIOS decode window, cbfstool add command is provided additional parameters for the decode window using --ext-win-base and --ext-win-size. It is the responsibility of the mainboard fmap author to ensure that the sections in the BIOS region do not cross 16MiB boundary as the host space windows are not contiguous. This change adds a build time check to ensure no sections in FMAP cross the 16MiB boundary. Even though the platform supports extended window, it depends upon the size of BIOS region (which in turn depends on SPI flash size) whether and how much of the additional window is utilized at runtime. This change also provides helper functions for rest of the coreboot components to query how much of the extended window is actually utilized.

2020-12-08commonlib/region: Allow multiple windows for xlate_region_devFurquan Shaikh
This change updates the translated region device (xlate_region_dev) to support multiple translation windows from the 1st address space to 2nd address space. The address spaces described by the translation windows can be non-contiguous in both spaces. This is required so that newer x86 platforms can describe memory mapping of SPI flash into multiple decode windows in order to support greater than 16MiB of memory mapped space. Since the windows can be non-contiguous, it introduces new restrictions on the region device ops - any operation performed on the translated region device is limited to only 1 window at a time. This restriction is primarily because of the mmap operation. The caller expects that the memory mapped space is contiguous, however, that is not true anymore. Thus, even though the other operations (readat, writeat, eraseat) can be updated to translate into multiple operations one for each access device, all operations across multiple windows are prohibited for the sake of consistency. It is the responsibility of the platform to ensure that any section that is operated on using the translated region device does not span multiple windows in the fmap description. One additional difference in behavior is xlate_region_device does not perform any action in munmap call. This is because it does not keep track of the access device that was used to service the mmap request. Currently, xlate_region_device is used only by memory mapped boot media on the backend. So, not doing unmap is fine. If this needs to be changed in the future, xlate_region_device will have to accept a pre-allocated space from the caller to keep track of all mapping requests.

2020-12-08soc/intel/common/gpio_defs: Add PAD_TRIG(OFF) in PAD_CFG_GPI_GPIO_DRIVERKaiyen Chang
Probabilistic interrupt storm is observed while kernel is configuring the GPIO for SD card CD pin. The root cause is that the macro PAD_CFG_GPI_GPIO_DRIVER isn't configuring trigger as PAD_TRIG(OFF). The way GPIO interrupts are handled is: 1. Pad is configured as input in coreboot. 2. Pad IRQ information is passed in ACPI tables to kernel. 3. Kernel configures the required pad trigger. Therefore, PAD_TRIG(OFF) should be added in PAD_CFG_GPI_GPIO_DRIVER to turn off the trigger while pad is configured as input in coreboot and then let kernel to configure the required pad trigger.

2020-12-04soc/intel/common/block/gpio: add code for NMI enablingMichael Niewöhner
Especially server boards, like the Supermicro X11SSM-F, often have a NMI button and NMI functionality that can be triggered via IPMI. The purpose of this is to cause the OS to create a system crashdump from a hang system or for debugging. Add code for enabling NMI interrupts on GPIOs configured with PAD_CFG_GPI_NMI. The enabling mechanism is the same as SMI, so the SMI function was copied and adapted. The `pad_community` struct gained two variables for the registers. Also register the NMI for LINT1 in the MADT in accordance to ACPI spec.

2020-12-03cbfs: Introduce cbfs_ro_map() and cbfs_ro_load()Julius Werner
This patch introduces two new CBFS API functions which are equivalent to cbfs_map() and cbfs_load(), respectively, with the difference that they always operate on the read-only CBFS region ("COREBOOT" FMAP section). Use it to replace some of the simple cases that needed to use cbfs_locate_file_in_region().

2020-12-02cbfs: Simplify load/map API names, remove type argumentsJulius Werner
This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file() to cbfs_map() and cbfs_load() respectively. This is supposed to be the start of a new, better organized CBFS API where the most common operations have the most simple and straight-forward names. Less commonly used variants of these operations (e.g. cbfs_ro_load() or cbfs_region_load()) can be introduced later. It seems unnecessary to keep carrying around "boot" in the names of most CBFS APIs if the vast majority of accesses go to the boot CBFS (instead, more unusual operations should have longer names that describe how they diverge from the common ones). cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly reap mappings when desired. A few new cbfs_unmap() calls are added to generic code where it makes sense, but it seems unnecessary to introduce this everywhere in platform or architecture specific code where the boot medium is known to be memory-mapped anyway. In fact, even for non-memory-mapped platforms, sometimes leaking a mapping to the CBFS cache is a much cleaner solution than jumping through hoops to provide some other storage for some long-lived file object, and it shouldn't be outright forbidden when it makes sense. Additionally, remove the type arguments from these function signatures. The goal is to eventually remove type arguments for lookup from the whole CBFS API. Filenames already uniquely identify CBFS files. The type field is just informational, and there should be APIs to allow callers to check it when desired, but it's not clear what we gain from forcing this as a parameter into every single CBFS access when the vast majority of the time it provides no additional value and is just clutter.

2020-11-20soc/intel/common/acpi: work around Windows crash on S0ix-enabled boardsMichael Niewöhner
Windows does not comply with the Low Power Idle S0 specification and crashes with an `INTERNAL_POWER_ERROR` bluescreen when function 1, does not return at least one device constraint, even when function 1 is announced as being not available by the enum function. Returning an empty package does not work. At least the following Windows versions were verified to be affected: - Windows 8.1 x64, release 6.3.9600 - Windoes 10 x64, version 1809, build 17763.379 - Windows 10 x64, version 1903, build 18362.53 - Windows 10 x64, version 2004, build 19041.508 - Windows 10 x64, version 20H2 / 2009, build 19042.450 To make Windows work on S0ix-enabled boards, return a dummy constraint package with a disabled dummy device. Since the device constraints are only used for debugging low power states in Linux and probably also in Windows, there shouldn't be any negative effect to S0ix. Real device constraint entries could be added at a later point, if needed. Note: to fully prevent the BSOD mentioned above the LPIT table is required on Windows, too. The patch for this is WIP, see CB:32350. If you want to test this, you need to applie the whole ACPI patch series including the hacky LPIT test implementation from CB:47242: https://review.coreboot.org/q/topic:%22low_power_idle_fix%22 Test: no bluescreen anymore on Clevo L140CU on all Windows versions listed above and S0ix gets detected in `powercfg -a`.

Rename LPID to PEPD for consistency. PEPD means "Power Engine Plug-In Device" and is the name Intel and vendors usually use, so let's comply.

2020-11-19soc/intel/common/acpi: move S0ix UUID to the conditionMichael Niewöhner
Move the UUID to the condition, since there is no need to assign a name when it is only used once. Also add a comment to make clear that the functions inside that condition are only used by the Low Power Idle S0 functionality, while the PEPD in general can be present on boards without S0ix capability, too. For details check CB:46469.
