* util/sconfig: Throw an error if override tree has no devicesFurquan Shaikh2019-04-241-0/+5
| | | | | | | | | | | | | | | | | If override tree does not have any device, then the chip info structure in it cannot be associated with the correct device and ends up being added as a standalone chip info structure without any device actually using it. This change prevents this condition by throwing an error during compilation.

* util/sconfig: Add support for overriding base tree properties/nodeFurquan Shaikh2018-06-252-10/+394
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* util/sconfig: Enable parsing of override device treeFurquan Shaikh2018-06-251-6/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This change allows sconfig utility to accept an extra optional parameter to specify override device tree that can be used to override the properties or add new devices in addition to that provided by base device tree. This is helpful for variants that share most of the devicetree but have to override certain registers or add some devices which might not be applicable to base devicetree. In order to support the override devicetree, following changes are made in this CL: 1. override_root_dev and override_root_bus are provided. 2. main() function is updated to accept an optional argument. 3. If override device file is provided, then parse_devicetree is called for override_devtree as well. This change in itself does not provide the override feature. It is only a small step towards the final goal. The override devicetree parsed by sconfig is currently unused.

* util/sconfig: Re-factor device structure in parse treeFurquan Shaikh2018-06-085-300/+410
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change re-factors the device structure in parse tree to be able to support multidev devices just like non-multidev devices. With this change, every device has a bus under it which is the parent of all devices that fall on the bus. 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. Also, the tree traversal to generate static.c is changed to breadth-first walk instead of using the next_sibling. BUG=b:80081934 TEST=Verified using abuild that all boards compile successfully.

* util/sconfig: Re-factor sconfig to not assume chip as deviceFurquan Shaikh2018-06-055-108/+195
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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>

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.

| | | | | | | | | | | | | | | | | | Use the second token for an i2c device entry in devicetree.cb to indicate if it should use 10-bit addressing or 7-bit. The default if not provided is to use 7-bit addressing, but it can be changed to 10-bit addressing with the ".1" suffix. For example: chip drivers/i2c/generic device i2c 3a.1 on end end Change-Id: I1d81a7e154fbc040def4d99ad07966fac242a472 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/14788 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Aaron Durbin <adurbin@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | Currently you cannot assign a string to a register in devicetree because the quotes are removed when parsing and the literal is assigned directly. Add a parse option for two double-quotation marks to indicate a string and return a quoted literal that can be assigned to a register with a 'const char *' type. Example: chip drivers/i2c/generic register "hid" = ""INT343B"" register "uid" = "1" device i2c 15 on end end Change-Id: I621cde1f7547494a8035fbbab771f29522da1687 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/14787 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
