2021-09-20device/mmio: Make buffer_to_fifo32() take a const bufferJulius Werner
The input buffer to the buffer_to_fifo family of functions is only read, so it can be a const pointer. (Also, remove the MIPS check in libpayload for these functions... the MIPS architecture has been removed a while ago.)

2021-08-20qualcomm/sc7180: Switch to common MIPI panel libraryJulius Werner
This patch changes the sc7180 boards to use the new common MIPI panel framework, which allows more flexible initialization command packing and sharing panel definitions between boards. (I'm taking the lane count control back out again for now, since it seems we only ever want 4 for now anyway, and if we ever have a need for a different lane count it's not clear whether that should be a property of the board or the panel or both. Better to leave that decision until we have a real use case.) Also, the code was not written to deal with DCS commands that were not a length divisible by 4 (it would read over the end of the command buffer). The corresponding kernel driver seems to pad the command with 0xff instead, let's do the same here. (Also increase the maximum allowed command length to 256 bytes, as per Qualcomm's recommendation.)

2021-08-18device: Move MIPI panel library from mainboard/google/kukui into commonJulius Werner
All boards that are trying to use MIPI panels eventually run into the problem that they need to store physical parameters and a list of DCS initialization commands for each panel, and these commands can be very different (e.g. a large amount of very short commands, a few very large commands, etc.). Finding a data format to fit all these different cases efficiently into the same structures keeps being a challenge, and the Kukui mainboard already once put a lot of effort into designing a clean, flexible and efficient solution for this. This patch moves that framework into a common src/device/mipi/ library where it can be used by other boards as well. (Also, this will hopefully allow us to save some duplicated work when using the same panel on different boards at some point.)

2021-05-24device: Consider fw_config probing in `is_dev_enabled()`Furquan Shaikh
With the introduction of fw_config support in coreboot, it is possible for mainboards to control the state of a device (on/off) in ramstage using fw_config probe conditions. However, the device tree in immutable in all other stages and hence `is_dev_enabled()` does not really reflect the true state as in ramstage. This change adds a call to `fw_config_probe_dev()` in `is_dev_enabled()` when device tree is immutable (by checking DEVTREE_EARLY) to first check if device is disabled because of device probe conditions. If so, then it reports device as being disabled. Else, dev->enabled is used to report the device state. This allows early stages (bootblock, romstage) to use `is_dev_enabled()` to get the true state of the device by taking probe conditions into account and eliminates the need for each caller to perform their own separate probing.

2021-03-24device/azalia_device.c: Unify `wait_for_valid` timeoutsAngel Pons
The timeout is never reached when the codec is functioning properly. Using a small timeout value can result in spurious errors with some codecs, e.g. a codec that is slow to respond but operates correctly. When a codec is non-operative, the timeout is only reached once per verb table, thus the impact on booting time is relatively small. So, use a reasonably long enough timeout to cover all possible cases. Remove the unconditional 25 µs delay and increase the timeout delay. The new value of 1 ms is the maximum of all existing implementations.

2021-03-15pciexp_device: Rewrite LTR configurationNico Huber
I was bugged by spurious "Failed to enable LTR" messages for years. Looking at the the current algorithm, it is flawed in multiple ways: * It looks like the author didn't know they implemented a recursive algorithm (pciexp_enable_ltr()) inside another recursive algorithm (pciexp_scan_bridge()). Thus, at every tree level, everything is run again for the whole sub- tree. * LTR is enabled no matter if `.set_ltr_max_latencies` is implemented or not. Leaving the endpoints' LTR settings at 0: They are told to always report zero tolerance. In theory, depending on the root-complex implementation, this may result in higher power consumption than without LTR messages. * `.set_ltr_max_latencies` is only considered for the direct parent of a device. Thus, even with it implemented, an endpoint below a (non-root) bridge may suffer from the 0 settings as described above. * Due to the double-recursive nature, LTR is enabled starting with the endpoints, then moving up the tree, while the PCIe spec tells us to do it in the exact opposite order. With the current implementation of pciexp_scan_bridge(), it is hard to hook anything in that runs for each device from top to bottom. So the proposed solution still adds some redundancy: First, for every device that uses pciexp_scan_bus(), we enable LTR if possible (see below). Then, when returning from the bus- scanning recursion, we enable LTR for every device and configure the maximum latencies (if supported). The latter runs again on all bridges, because it's hard to know if pciexp_scan_bus() was used for them. When to enable LTR: * For all devices that implement `.set_ltr_max_latencies`. * For all devices below a bridge that has it enabled already.

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.

There's many copies of this function in the tree. Make the copy in azalia_device.c non-static and rename it to `azalia_set_bits`, then replace all other copies with it. Since azalia_device.c is only built when AZALIA_PLUGIN_SUPPORT is selected, select it where necessary. This has the side-effect of building hda_verb.c from the mainboard directory. If this patch happens to break audio on a mainboard, it's because its hda_verb.c was always wrong but wasn't being compiled.

2020-12-14drivers: Replace multiple fill_lb_framebuffer with single instancePatrick Rudolph
Currently it's not possible to add multiple graphics drivers into one coreboot image. This patch series will fix this issue by providing a single API that multiple graphics drivers can use. This is required for platforms that have two graphic cards, but different graphic drivers, like Intel+Aspeed on server platforms or Intel+Nvidia on consumer notebooks. The goal is to remove duplicated fill_fb_framebuffer(), the advertisment of multiple independent framebuffers in coreboot tables, and better runtime/build time graphic configuration options. Replace all duplications of fill_fb_framebuffer and provide a single one in edid_fill_fb.c. Should not change the current behaviour as still only one graphic driver can be active at time.

Add a NULL check and only skip setting the default operations if `.ops` was set by a driver. It's fairly unlikely that some- body adds a driver and forgets the `.ops` pointer. So this is mostly to increase readability: Nobody should have to wonder if we're missing a NULL-check. The condition is moved out of the loop to reduce indentation levels. Alternatively, we could jusk skip drivers that don't have `.ops` set (i.e. continue the loop).

2020-10-21device: Allow virtual/generic devices under PCI in devicetreeDuncan Laurie
This change allows a generic device to be described in the devicetree under a PCI device, such as a root port. Previously any device under a PCI device was expected to also be a PCI device and that does not allow for a virtual/generic device to be present, for example to provide ACPI properties for a root port. The changes are: - Ignore non-PCI devices found under a PCI device when scanning and do not print an error for each devfn scanned. - Don't treat non-PCI devices as leftover and remove them, instead enable them as a static device. - Don't attempt to configure a static device in the tree that is not a PCIe device type. With these changes it is now possible to have a generic device under a PCI device, for example in a USB4/TBT root port (PCIe hotplug device) this generic device will add ACPI properties for the PCIe tunnel routed to the external port: device pci 07.0 on chip soc/intel/common/block/pcie device generic 0 on end end end TEST=boot on volteer with the USB4 root port devices in chipset.cb and ensure they are enabled properly and there are no errors printed in the coreboot log, and that the device properties are created in the SSDT.

2020-08-31device: Add method to configure bus mastering based on KconfigFelix Singer
The bus master bit is set at many places in coreboot's code, but the reason for that is not quite clear. We examined not setting the bus master bit whereever possible and tried booting without it, which worked fine for internal PCI devices but not for PCIe. As a PCIe device we used a Samsung M.2 NVMe SSD. For security reasons, we would like to disable bus mastering where possible. Depending on the device, bus mastering might get enabled by the operating system (e.g. for iGPU) and it might be required for some devices to work properly. However, the idea is to leave it disabled and configure the IOMMU first before enabling it. To have some sort of "backwards compatibility", add a method which configures bus mastering based on an additional config option. Since CB:42460 makes usage of this treewide, enable it by default to keep the current behaviour for now. Tested with Siemens/Chili, a Coffee Lake based platform.
