2021-01-11util/sconfig: Emit chip config pointers for PCI devices on root busFurquan Shaikh
This change emits chip config pointers for PCI devices on root bus in static_devices.h so that the config structure can be accessed directly without having to reference the device structure. This allows the linker to optimize out unused parts of the device tree from early stages like bootblock.

2020-12-28device + util/sconfig: introduce new device `gpio`Michael Niewöhner
Introduce a new device `gpio` that is going to be used for generic abstraction of gpio operations in the devicetree. The general idea behind this is that every chip can have gpios that shall be accessible in a very generic way by any driver through the devicetree. The chip that implements the chip-specific gpio operations has to assign them to the generic device operations struct, which then gets assigned to the gpio device during device probing. See CB:48583 for how this gets done for the SoCs using intelblocks/gpio. The gpio device then can be added to the devicetree with an alias name like in the following example: chip soc/whateverlake device gpio 0 alias soc_gpio on end ... end Any driver that requires access to this gpio device needs to have a device pointer (or multiple) and an option for specifying the gpio to be used in its chip config like this: struct drivers_ipmi_config { ... DEVTREE_CONST struct device *gpio_dev; u16 post_complete_gpio; ... }; The device `soc_gpio` can then be linked to the chip driver's `gpio_dev` above by using the syntax `use ... as ...`, which was introduced in commit 8e1ea52: chip drivers/ipmi use soc_gpio as gpio_dev register "bmc_jumper_gpio" = "GPP_D22" ... end The IPMI driver can then use the generic gpio operations without any knowlege of the chip's specifics: unsigned int gpio_val; const struct gpio_operations *gpio_ops; gpio_ops = dev_get_gpio_ops(conf->gpio_dev); gpio_val = gpio_ops->get(conf->bmc_jumper_gpio); For a full example have a look at CB:48096 and CB:48095. This change adds the new device type to sconfig and adds generic gpio operations to the `device_operations` struct. Also, a helper for getting the gpio operations from a device after checking them for NULL pointers gets added. Successfully tested on Supermicro X11SSM-F with CB:48097, X11SSH-TF with CB:48711 and OCP DeltaLake with CB:48672.

2020-10-26sconfig: Split up sconfig-generated static.hTim Wawrzynczak
Currently sconfig generates a `static.h` to accompany `static.c`. However, some payloads may decide they would like to consume the FW_CONFIG macros as well. The current state of `static.h` makes this impossible (relying on `device/device.h`). This patch splits up `static.h` into 3 files: `static.h, `static_devices.h`, and `static_fw_config.h`. `static.h` simply includes the other two `.h` files to ensure no changes are needed to other code. `static_devices.h` contains the extern'd definitions of the device names recently introduced to sconfig. `static_fw_config.h` contains the FW_CONFIG_FIELD_* macros only, which makes it easily consumable by a payload which wishes to use FW_CONFIG. Also refactor the generation of all these output files, as the code was getting messy.

2020-09-11sconfig: Allow to link devices to other device's driversNico Huber
Rarely, the driver of one device needs to know about another device that can be anywhere in the device hierarchy. Current applications boil down to EEPROMs that store information that is consumed by some code (e.g. MAC address). The idea is to give device nodes in the `devicetree.cb` an alias that can later be used to link it to a device driver's `config` structure. The driver has to declare a field of type `struct device *`, e.g. struct some_chip_driver_config { DEVTREE_CONST struct device *needed_eeprom; }; In the devicetree, the referenced device gets an alias, e.g. device i2c 0x50 alias my_eeprom on end The author of the devicetree is free to choose any alias name that is unique in the devicetree. Later, when configuring the driver the alias can be used to link the device with the field of a driver's config: chip some/chip/driver use my_eeprom as needed_eeprom end Override devices can add an alias if it does not exist, but cannot change the alias for a device that already exists. Alias names are checked for conflicts both in the base tree and in the override tree. References are resolved after the tree is parsed so aliases and references do not need to be in a specific order in the tree.

In addition these fields and options can be used to probe for a device and have that device be disabled if it is not found at boot time. New tokens: fw_config: top level token, table can be defined before chips field: define field in the mask with the start and end bits option: define option in a field with the value of the field probe: indicate that a device should probe by field and option Example: fw_config field FEATURE 0 0 option DISABLE 0 option ENABLE 1 end end chip drivers/generic/feature device generic 0 on probe FEATURE ENABLE end end Variants can add new fields and add new options to existing fields in overridetree.cb but cannot redefine an existing option. Devices can have multiple probe tokens, and the device will be considered to be found if any of them return true. The output from defining this field are: 1) the various fields and options will be added as macro constants to static.h and can be used by fw_config for probing. 2) the probe entries will result in a list of fields/options to probe that is added to the resulting struct device and handled by coreboot.

2020-05-07util/sconfig: Drop use of ref_count for chip_instanceFurquan Shaikh
chip_instance structure currently uses a ref_count to determine how many devices hold reference to that instance. If the count drops to zero, then it is assumed that the chip instance is a duplicate in override tree and has a similar instance that is already overriden in base device tree. ref_count is currently decremented whenever a device in override tree matches the one in base device tree and the registers from the override tree instance are copied over to the base tree instance. On the other hand, if a device in override tree does not match any device in base tree under a given parent, then the device is added to base tree and all the devices in its subtree that hold pointers to its parent chip instance are updated to point to the parent's chip instance in base tree. This is done as part of update_chip_pointers. However, there are a couple of issues that this suffers from: a) If a device is present only in override tree and it does not have its own chip (i.e. pointing to parent's chip instance), then it results in sconfig emiiting parent's chip instance (which can be the SoC chip instance) in static.c even though it is unused. This is because update_chip_pointers() does not call delete_chip_instance() before reassigning the chip instance pointer. b) If a device is added under root device only in the override tree and it does not have its own chip instance (i.e. uses SoC chip instance), then it results in sconfig emitting a copy of the SoC chip instance and setting that as chip_ops for this new device in the override tree. In order to fix the above issues, this change drops the ref_count field from chip_instance structure and instead adds a forwarding pointer `base_chip_instance`. This is setup as per the following rules: 1. If the instance belongs to base devicetree, base_chip_instance is set to NULL. 2. If the instance belongs to override tree, then it is set to its corresponding chip instance in base tree (if present), else set to NULL. State of base_chip_instance is then used when emitting chips and devices using the following rules: 1. If a chip_instance has non-NULL base_chip_instance, then that chip instance is not emitted to static.c 2. When emitting chip_ops for a device, base_chip_instance is used to determine the correct chip instance name to emit. BUG=b:155549176 TEST=Verified that the static.c file generated for base/override tree combination is correct when new devices without chips are added only to override tree.

2020-05-07util/sconfig: Move chip instance id assignment to emit_chips()Furquan Shaikh
This change moves the assignment of id for chip instance from new_chip_instance() to emit_chips(). This is similar to the previous change for moving dev id assignment to happen much later. This ensures that the same ID gets assigned to a chip when adding support for device trees which makes it easier to compare static.c files.

2020-05-07util/sconfig: Drop id from struct device maintained by sconfigFurquan Shaikh
This change drops the id field from struct device as used by sconfig. It was primarily used for generating unique device names. This was maintained within device structure so that the order in which the device tree entries were parsed is clear. Since the ids are assigned in parsing order, it is problematic when a device is moved from base devicetree to override tree. The entire parsing order changes which makes it really difficult to compare what really changed in static.c file. By moving the dev name assignment to happen later when doing pass0 of static.c generation, the difference in static.c file is minimized when adding support for override trees.

2020-02-08Add configurable ramstage support for minimal PCI scanningRonald G. Minnich
This CL has changes that allow us to enable a configurable ramstage, and one change that allows us to minimize PCI scanning. Minimal scanning is a frequently requested feature. To enable it, we add two new variables to src/Kconfig CONFIGURABLE_RAMSTAGE is the overall variable controlling other options for minimizing the ramstage. MINIMAL_PCI_SCANNING is how we indicate we wish to enable minimal PCI scanning. Some devices must be scanned in all cases, such as 0:0.0. To indicate which devices we must scan, we add a new mandatory keyword to sconfig It is used in place of on, off, or hidden, and indicates a device is enabled and mandatory. Mandatory devices are always scanned. When MINIMAL_PCI_SCANNING is enabled, ONLY mandatory devices are scanned. We further add support in src/device/pci_device.c to manage both MINIMAL_PCI_SCANNING and mandatory devices. Finally, to show how this works in practice, we add mandatory keywords to 3 devices on the qemu-q35. TEST= 1. This is tested and working on the qemu-q35 target. 2.

This patch creates a new commonlib/bsd subdirectory with a similar purpose to the existing commonlib, with the difference that all files under this subdirectory shall be licensed under the BSD-3-Clause license (or compatible permissive license). The goal is to allow more code to be shared with libpayload in the future. Initially, I'm going to move a few files there that have already been BSD-licensed in the existing commonlib. I am also exracting most contents of the often-needed <commonlib/helpers.h> as long as they have either been written by me (and are hereby relicensed) or have an existing equivalent in BSD-licensed libpayload code. I am also relicensing <commonlib/compression.h> (written by me) and <commonlib/compiler.h> (same stuff exists in libpayload). Finally, I am extracting the cb_err error code definitions from <types.h> into a new BSD-licensed header so that future commonlib/bsd code can build upon a common set of error values. I am making the assumption here that the enum constants and the half-sentence fragments of documentation next to them by themselves do not meet the threshold of copyrightability.

2019-07-12util/sconfig: Fix compile error with older glibc-headersWerner Zeh
In patch e29a6ac16a9f478fc00ce7cb83f3779954e3168d (util/sconfig: Add commonlib/helpers.h) helpers.h has been added to the include-list. In headers.h we have a definition for __unused: On a host system environment where glibc-headers-2.12-1.212 is installed, a file included by <sys/stat.h> called bits/stat.h have the following content on line 105 and onwards: long int __unused[3]; where the mentioned part is part of the structure called struct stat. If we include commonlib/helpers.h _before_ <sys/stat.h>, the symbol for __unused will be defined by the preprocessor to be '__attribute__((unused))', therefore the above mentioned structure member will be expanded by the preprocessor to be 'long int __attribute__((unused))[3];', which is not a valid C syntax and therefore produces a compile error for sconfig tool. To handle this case we need to make sure commonlib/helpers.h is included _after_ <sys/stat.h>. As the needed part of stat.h (which is struct stat) is only used in main.c it is safe to move the include from sconfig.h directly into main.c while taking care of the order.

2018-06-25util/sconfig: Add support for overriding base tree properties/nodeFurquan Shaikh
This change adds support to allow variants to override the devices and properties in base device tree by providing an override device tree. It works as follows: 1. Both base and override device trees are parsed from provided input files. 2. Walk through the trees in lockstep fashion using depth-first traversal checking if a node in override tree has a matching node in base tree. - If matching node is found, then update the properties of base node using the override node. Continue walking the children of the nodes. - If matching node is not found, then copy the entire override subtree of the node under the current base parent. In addition to that, chip instance pointers of the nodes in override tree need to be updated if they were pointing to the override parents chip instance. Since chip always expects a device to be present, it leads to a side-effect that overriding chip registers requires that a device is always provided for the chip in the override tree as well.

2018-06-05util/sconfig: Re-factor sconfig to not assume chip as deviceFurquan Shaikh
This change adds a new structure "struct chip" to identify elements of type chip rather than re-using the structure for device. Until now chip was treated as a device while generating the parse tree and then device tree postprocessing skipped over all the chip entries in children and sibling pointers of device nodes. With this change, the device tree will only contain struct device in the parsed tree. It helps by avoiding unnecessary pointers to chip structure as children or next_sibling and then skipping those elements in post processing. Every device can then hold a pointer to its chip. When generating static.c, chip structure is emitted before device structure to ensure that the device structure has chip within its scope. Externally, the only visible change in static.c should be the order in which chip/device elements are emitted i.e. previously all chips under a particular device were emitted to static.c and then the devices using those chips. Now, all chips are emitted before all the devices in static.c BUG=b:80081934 TEST=Verified that abuild is successful for all boards. Also, verified that static.c generated for eve, kahlee, scarlet, asrock imb_a180 is unchanged from before in node definitions.

2018-05-11devicetree: Add USB device typeDuncan Laurie
This commit adds support for describing USB ports in devicetree.cb. It allows a USB port location to be described in the tree with configuration information, and ACPI code to be generated that provides this information to the OS. A new scan_usb_bus() is added that will scan bridges for devices so a tree of ports and hubs can be created. The device address is computed with a 'port type' and a 'port id' which is flexible for SOC to handle depending on their specific USB setup and allows USB2 and USB3 ports to be described separately. For example a board may have devices on two ports, one with a USB2 device and one with a USB3 device, both of which are connected to an xHCI controller with a root hub: xHCI | RootHub | | USB2[0] USB3[2] device pci 14.0 on chip drivers/usb/acpi register "name" = ""Root Hub"" device usb 0.0 on chip drivers/usb/acpi register "name" = ""USB 2.0 Port 0"" device usb 2.0 on end end chip drivers/usb/acpi register "name" = ""USB 3.0 Port 2"" device usb 3.2 on end end end end end Change-Id: I64e6eba503cdab49be393465b535e139a8c90ef4 Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: https://review.coreboot.org/26169 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>

2017-04-25lib: provide clearer devicetree semanticsAaron Durbin
The devicetree data structures have been available in more than just ramstage and romstage. In order to provide clearer and consistent semantics two new macros are provided: 1. DEVTREE_EARLY which is true when !ENV_RAMSTAGE 2. DEVTREE_CONST as a replacment for ROMSTAGE_CONST The ROMSTAGE_CONST attribute is used in the source code to mark the devicetree data structures as const in early stages even though it's not just romstage. Therefore, rename the attribute to DEVTREE_CONST as that's the actual usage. The only place where the usage was not devicetree related is console_loglevel, but the same name was used for consistency. Any stage that is not ramstage has the const C attribute applied when DEVTREE_CONST is used.

2012-08-08Fix SMBIOS generationStefan Reinauer
Dropping mainboard's chip.h broke execution of the mainboard's enable function and the addition of mainboard specific smbios tables. The former was fixed by Kyosti in http://review.coreboot.org/1374 This patch fixes the breakage in static.c and also backs out a small portion of Kyosti's patch (because it's not needed anymore) Change-Id: I6fdea9cbb8c6041663bd36f68f1cae4b435c1f9b Signed-off-by: Stefan Reinauer <reinauer@google.com> Reviewed-on: http://review.coreboot.org/1421 Tested-by: build bot (Jenkins) Reviewed-by: Kyösti Mälkki <kyosti.malkki@gmail.com> Reviewed-by: Anton Kochkov <anton.kochkov@gmail.com>
2012-08-04Make the device tree available in the rom stageStefan Reinauer
We thought about two ways to do this change. The way we decided to try was to 1. drop all ops from devices in romstage 2. constify all devices in romstage (make them read-only) so we can compile static.c into romstage 3. the device tree "devices" can be used to read configuration from the device tree (and nothing else, really) 4. the device tree devices are accessed through struct device * in romstage only. device_t stays the typedef to int in romstage 5. Use the same static.c file in ramstage and romstage We declare structs as follows: ROMSTAGE_CONST struct bus dev_root_links[]; ROMSTAGE_CONST is const in romstage and empty in ramstage; This forces all of the device tree into the text area. So a struct looks like this: static ROMSTAGE_CONST struct device _dev21 = { #ifndef __PRE_RAM__ .ops = 0, #endif .bus = &_dev7_links[0], .path = {.type=DEVICE_PATH_PCI,{.pci={ .devfn = PCI_DEVFN(0x1c,3)}}}, .enabled = 0, .on_mainboard = 1, .subsystem_vendor = 0x1ae0, .subsystem_device = 0xc000, .link_list = NULL, .sibling = &_dev22, #ifndef __PRE_RAM__ .chip_ops = &southbridge_intel_bd82x6x_ops, #endif .chip_info = &southbridge_intel_bd82x6x_info_10, .next=&_dev22 }; Change-Id: I722454d8d3c40baf7df989f5a6891f6ba7db5727 Signed-off-by: Ronald G.

2012-07-13MPTAPLE: generate from devicetree.cbSven Schnelle
This patch adds support for autogenerating the MPTABLE from devicetree.cb. This is done by a write_smp_table() declared weak in mpspec.c. If the mainboard doesn't provide it's own function, this generic implementation is called. Syntax in devicetree.cb: ioapic_irq <APICID> <INTA|INTB|INTC|INTD> <INTPIN> The ioapic_irq directive can be used in pci and pci_domain devices. If there's no directive, the autogen code traverses the tree back to the pci_domain and stops at the first device which such a directive, and use that information to generate the entry according to PCI IRQ routing rules.

2011-12-24Sconfig: parse Kconfig options from devicetree.cbKyösti Mälkki
Mainboard and chip Kconfig files have several build options that are redundant with information in devicetree.cb. This patch enables sconfig to auto-generate equivalent configuration. sconfig -s Generates mainboard's static.c file, as before. sconfig -b This operation creates mainboard's bootblock init code. By default, for every chip listed in mainboard/devicetree.cb, if there is a chip/bootblock.c file, the init function is called. A mainboard/bootblock.c file can be added to override default behaviour. sconfig -k This operation generates select -options for component paths.
