sconfig: Allow to specify device operations Currently we only have runtime mechanisms to assign device operations to a node in our devicetree (with one exception: the root device). The most common method is to map PCI IDs to the device operations with a `struct pci_driver`. Another accustomed way is to let a chip driver assign them. For very common drivers, e.g. those in soc/intel/common/blocks/, the PCI ID lists grew very large and are incredibly error-prone. Often, IDs are missing and sometimes IDs are added almost mechanically without checking the code for compatibility. Maintaining these lists in a central place also reduces flexibility. Now, for onboard devices it is actually unnecessary to assign the device operations at runtime. We already know exactly what operations should be assigned. And since we are using chipset devicetrees, we have a perfect place to put that information. This patch adds a simple mechanism to `sconfig`. It allows us to speci- fy operations per device, e.g. device pci 00.0 alias system_agent on ops system_agent_ops end The operations are given as a C identifier. In this example, we simply assume that a global `struct device_operations system_agent_ops` exists.

device + util/sconfig: introduce new device `gpio` 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.

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.

device + util/sconfig: introduce new device `gpio` 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.

sconfig: Add support for firmware configuration This change adds support to sconfig for generating the firmware configuration field and option definitions in devicetree.cb. 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.

sconfig: Allow to specify device operations Currently we only have runtime mechanisms to assign device operations to a node in our devicetree (with one exception: the root device). The most common method is to map PCI IDs to the device operations with a `struct pci_driver`. Another accustomed way is to let a chip driver assign them. For very common drivers, e.g. those in soc/intel/common/blocks/, the PCI ID lists grew very large and are incredibly error-prone. Often, IDs are missing and sometimes IDs are added almost mechanically without checking the code for compatibility. Maintaining these lists in a central place also reduces flexibility. Now, for onboard devices it is actually unnecessary to assign the device operations at runtime. We already know exactly what operations should be assigned. And since we are using chipset devicetrees, we have a perfect place to put that information. This patch adds a simple mechanism to `sconfig`. It allows us to speci- fy operations per device, e.g. device pci 00.0 alias system_agent on ops system_agent_ops end The operations are given as a C identifier. In this example, we simply assume that a global `struct device_operations system_agent_ops` exists.

device + util/sconfig: introduce new device `gpio` 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.

The most common method is to map PCI IDs to the device operations with a `struct pci_driver`. Another accustomed way is to let a chip driver assign them.

device + util/sconfig: introduce new device `gpio` 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.

device + util/sconfig: introduce new device `gpio` Introduce a new device `gpio` that is going to be used for generic abstraction of gpio operations in the devicetree.

sconfig: Allow to link devices to other device's drivers 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.

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.

case 60: /* fw_config_option: FW_CONFIG_OPTION STRING NUMBER */
device + util/sconfig: introduce new device `gpio` 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.

sconfig: Add support for firmware configuration This change adds support to sconfig for generating the firmware configuration field and option definitions in devicetree.cb. 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.

sconfig: Allow to specify device operations Currently we only have runtime mechanisms to assign device operations to a node in our devicetree (with one exception: the root device). The most common method is to map PCI IDs to the device operations with a `struct pci_driver`. Another accustomed way is to let a chip driver assign them. For very common drivers, e.g. those in soc/intel/common/blocks/, the PCI ID lists grew very large and are incredibly error-prone. Often, IDs are missing and sometimes IDs are added almost mechanically without checking the code for compatibility. Maintaining these lists in a central place also reduces flexibility. Now, for onboard devices it is actually unnecessary to assign the device operations at runtime. We already know exactly what operations should be assigned. And since we are using chipset devicetrees, we have a perfect place to put that information. This patch adds a simple mechanism to `sconfig`. It allows us to speci- fy operations per device, e.g. device pci 00.0 alias system_agent on ops system_agent_ops end The operations are given as a C identifier. In this example, we simply assume that a global `struct device_operations system_agent_ops` exists.

YYABORT, YYACCEPT, or YYERROR immediately after altering yychar or
if it invokes YYBACKUP. In the case of YYABORT or YYACCEPT, an
