2023-02-06device/pci_device.c: Add way to limit max bus numbersArthur Heymans
By default this limits PCI buses to CONFIG_MMCONF_BUS_NUMBER. Some platforms have multiple PCI root busses (e.g. xeon_sp), where bus numbers are limited. This provides a basic check. On some platforms it looks like programming 0xff to the subordinate bus number confuses and hangs the hardware.

Intel Ice Lake is unmaintained and the only user of this platform ever was the Intel CRB (Customer Reference Board).

2022-11-24src/device + util/sconfig: Introduce new device 'mdio'Mario Scheithauer
This patch extends the available device paths with a new device 'mdio'. MDIO is the 'Management Data Input/Output' called interface which is used to access an Ethernet PHY behind a MAC to change settings. The real payload data path is not handled by this interface. To address the PHY correctly on the MDIO bus, there is a 5 bit address needed, which often can be configured via pins on the mainboard. Therefore, the new introduced device has an 'addr' field to define its address. If one wants to use a MDIO device in devicetree, the syntax is straight forward (example): device mdio 0x2 on end As the MDIO interface is driven by the MAC, most likely this MDIO device will be hooked in as a child device of the (PCI attached) MAC device. With the new introduced ops_mdio a new interface is added to provide an API for read and write access over MDIO.

2022-09-04pciexp_device: Propagate above-4G flag to all hotplug devicesNico Huber
The `IORESOURCE_ABOVE_4G` flag was only explicitly set for our dummy device that reserves resources behind a hotplug port. The current re- source allocator implicitly extends this to all devices below the port, including real ones. Let's make that explicit, so future changes to the allocator can't break this rule.

2022-02-16device: Add support for PCIe Resizable BARsTim Wawrzynczak
Section 7.8.6 of the PCIe spec (rev 4) indicates that some devices can indicates support for "Resizable BARs" via a PCIe extended capability. When support this capability is indicated by the device, the size of each BAR is determined in a different way than the normal "moving bits" method. Instead, a pair of capability and control registers is allocated in config space for each BAR, which can be used to both indicate the different sizes the device is capable of supporting for the BAR (powers-of-2 number of bits from 20 [1 MiB] to 63 [8 EiB]), and to also inform the device of the size that the allocator actually reserved for the MMIO range. This patch adds a Kconfig for a mainboard to select if it knows that it will have a device that requires this support during PCI enumeration. If so, there is a corresponding Kconfig to indicate the maximum number of bits of address space to hand out to devices this way (again, limited by what devices can support and each individual system may want to support, but just like above, this number can range from 20 to 63) If the device can support more bits than this Kconfig, the resource request is truncated to the number indicated by this Kconfig. BUG=b:214443809 TEST=compile (device with this capability not available yet), also verify that no changes are seen in resource allocation for google/brya0 before and after this change.

This patch provides a function similar to pciexp_find_extended_cap that can be used to search through multiple instances of the same capability by returning the offset of the next extended capability of the given type following the passed-in offset. The base functionality of searching for a given capability from an offset is extracted to a local helper function and both pciexp_find_extended_cap and pciexp_find_next_extended_cap use this helper.
