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.

2020-01-28commonlib: Add commonlib/bsdJulius Werner
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.

2019-11-26util/sconfig: Fix illogical override rule for resourceBill XIE
The old logic only uses the type to identify resources, which makes a resource in override tree overriding the first resource with the same type (but possibly different index) in base tree, and resources with same type (but again different index) in override tree overriding each other. Resources had better be identified with both their type and index.

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.

2018-06-25util/sconfig: Enable parsing of override device treeFurquan Shaikh

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.

2018-06-08util/sconfig: Re-factor device structure in parse treeFurquan Shaikh
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.

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.

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.

2016-05-16sconfig: Add a new generic device typeDuncan Laurie
Add support for a basic generic device in the devicetree to bind to a device that does not have a specific bus, but may need to be described in tables for the operating system. For instance some chips may have various GPIO connections that need described but do not fall under any other device. In order to support this export the basic 'scan_static_bus()' that can be used in a device_operations->scan_bus() method to scan for the generic devices. It has been possible to get a semi-generic device by using a fake PNP device, but that isn't really appropriate for many devices. Also Re-generate the shipped files for sconfig. Use flex 2.6.0 to avoid everything being rewritten. Clean up the local paths that leak into the generated configs.

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>
