	We all knew this was coming, 32 bits is never enough. Doing this early so that it doesn't affect too much code yet. Take care of every usage of fw_config throughout the codebase so the conversion is all done at once. BUG=b:169668368 TEST=Hacked up this code to OR 0x1_000_0000 with CBI-sourced FW_CONFIG and verify the console print contained that bit.

2020-10-09	sconfig: Allow chipset to provide a base devicetree	Duncan Laurie
	This change extends the devicetree override one more layer and allows the chipset to provide the base devicetree. This allows the chipset to assign alias names to devices as well as set default register values. This works for both the baseboard devicetree.cb as well as variant overridetree.cb. chipset.cb: device pci 15.0 alias i2c0 off end devicetree.cb: device ref i2c0 on end BUG=b:156957424 Change-Id: Ia7500a62f6211243b519424ef3834b9e7615e2fd Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/44037 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Nico Huber <nico.h@gmx.de> Reviewed-by: Furquan Shaikh <furquan@google.com>
2020-09-11	sconfig: Allow to link devices to other device's drivers	Nico 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.

2020-06-02	sconfig: Add support for firmware configuration	Duncan Laurie
	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.

2020-05-07	util/sconfig: Drop use of ref_count for chip_instance	Furquan 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.

2020-05-07	util/sconfig: Drop id from struct device maintained by sconfig	Furquan 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.

2020-02-08	Add configurable ramstage support for minimal PCI scanning	Ronald 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.

2019-07-12	util/sconfig: Fix compile error with older glibc-headers	Werner 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.

2018-06-25	util/sconfig: Add support for overriding base tree properties/node	Furquan 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.

If there are duplicate entries in the devicetree, then there will be multiple buses under the device and each bus will have its own set of children. The tree starts out with a root device which has a root bus under it. This is a special device which is created statically and its parent is its own root bus. When parsing the device tree file, devices get added under the root bus as children. Since this change re-organizes the way devicetree is represented, it gets rid of latestchild and next_sibling pointers from struct device.

2018-06-05	util/sconfig: Re-factor sconfig to not assume chip as device	Furquan 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.

2015-05-21	Remove address from GPLv2 headers	Patrick Georgi
	As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA[, ]02110-1301[, ]USA:Foundation, Inc.:" {} + $ find -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]Suite 330, Boston, MA 02111-1307[, ]USA:Foundation, Inc.:" {} + $ find -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \.patch \ -a \! -name \_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>

2012-07-13	MPTAPLE: generate from devicetree.cb	Sven 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.
