pci: mediatek: add support for multiple ports in mediatek pcie gen3 driver

2025-01-23T18:11:49Z

One MediaTek PCIe Gen3 controller has only one port, where PCI bus 0 on this port represents the controller itself and bus 1 represents the external PCIe device. If multiple PCIe controllers are probed in U-Boot, U-Boot will use bus numbers greater than 2 as input parameters. Therefore, we should convert the BDF bus number to either 0 or 1 by subtracting the offset by controller->seq_. Signed-off-by: Sam Shih Signed-off-by: Weijie Gao

Merge patch series "upl: Prerequite patches for updated spec"

2025-01-22T23:08:47Z

Simon Glass says: The current UPL spec[1] has been tidied up and improved over the last year, since U-Boot's original UPL support was written. This series includes some prerequisite patches needed for the real UPL patches. It is split from [2] [1] https://github.com/UniversalPayload/spec/tree/3f1450d [2] https://patchwork.ozlabs.org/project/uboot/list/?series=438574&state=* Link: https://lore.kernel.org/r/20250111000029.245022-1-sjg@chromium.org

Add this information to the handoff structure so that it is available to U-Boot proper. Update bochs and the video handoff. Signed-off-by: Simon Glass

pci: Add support for Qualcomm PCIe controller

2025-01-22T15:43:54Z

Add support for the PCIe busses on Qualcomm platforms, by using the pcie_dw_common infrastructure. The driver is based on the Linux driver but only supporting the "1_9_0" and compatible platforms like: - sa8540p - sc7280 - sc8180x - sc8280xp - sdm845 - sdx55 - sm8150 - sm8250 - sm8350 - sm8450 - sm8550 - sm8650 - x1e80100 But it has only been tested on: - sc7280 - sm8550 - sm8650 - x1e80100 It supports setting the IOMMU SID table for supported platforms.

Merge patch series "Implement ACPI on aarch64"

2024-10-28T00:44:13Z

Patrick Rudolph says: Based on the existing work done by Simon Glass this series adds support for booting aarch64 devices using ACPI only. As first target QEMU SBSA support is added, which relies on ACPI only to boot an OS. As secondary target the Raspberry Pi4 was used, which is broadly available and allows easy testing of the proposed solution. The series is split into ACPI cleanups and code movements, adding Arm specific ACPI tables and finally SoC and mainboard related changes to boot a Linux on the QEMU SBSA and RPi4. Currently only the mandatory ACPI tables are supported, allowing to boot into Linux without errors. The QEMU SBSA support is feature complete and provides the same functionality as the EDK2 implementation. The changes were tested on real hardware as well on QEMU v9.0: qemu-system-aarch64 -machine sbsa-ref -nographic -cpu cortex-a57 \ -pflash secure-world.rom \ -pflash unsecure-world.rom qemu-system-aarch64 -machine raspi4b -kernel u-boot.bin -cpu cortex-a72 \ -smp 4 -m 2G -drive file=raspbian.img,format=raw,index=0 \ -dtb bcm2711-rpi-4-b.dtb -nographic Tested against FWTS V24.03.00. Known issues: - The QEMU rpi4 support is currently limited as it doesn't emulate PCI, USB or ethernet devices! - The SMP bringup doesn't work on RPi4, but works in QEMU (Possibly cache related). - PCI on RPI4 isn't working on real hardware since the pcie_brcmstb Linux kernel module doesn't support ACPI yet.

arm: mach-bcm283x: Bring in some header files from tianocore

2024-10-27T23:24:13Z

These header files presumably duplicate things already in the U-Boot devicetree. For now, bring them in to get the ASL code and ACPI table code to compile.
