https://source.denx.de/u-boot/custodians/u-boot-socfpga into next SoCFPGA updates for v2025.10: CI: https://source.denx.de/u-boot/custodians/u-boot-socfpga/-/pipelines/27762 This pull request brings a set of updates across SoCFPGA platforms covering Agilex5, Agilex7, N5X, and Stratix10. The changes include: * Agilex5 enhancements: - USB3.1 enablement and DWC3 host driver support - System Manager register configuration for USB3 - Watchdog timeout increase and SDMMC clock API integration - dcache handling improvements in SMC mailbox path - Enable SPL_SYS_DCACHE_OFF in defconfig * Clock driver improvements: - Introduce dt-bindings header for Agilex clocks - Add enable/disable API and EMAC clock selection fixes - Replace manual shifts with FIELD_GET usage * DDR updates: - IOSSM mailbox compatibility check - Correct DDR calibration status handling * Device tree changes: - Agilex5: disable cache allocation for reads - Stratix10: add NAND IP node - Enable driver model watchdog - Enable USB3.1 node for Agilex5 * Config cleanups: - Simplify Agilex7 VAB defconfig - Remove obsolete SYS_BOOTM_LEN from N5X VAB config - Enable CRC32 support for SoCFPGA - Increase USB hub debounce timeout Overall this set improves reliability of DDR and cache flows, adds missing USB and MMC features for Agilex5, and refines clock and configuration handling across platforms. This patch set has been tested on Agilex 5 devkit, and Agilex devkit.
2025-09-25pci: pcie-rcar-gen4: Add missing 1ms delay after PWR reset assertionMarek Vasut
R-Car V4H Reference Manual R19UH0186EJ0130 Rev.1.30 Apr. 21, 2025 page 585 Figure 9.3.2 Software Reset flow (B) indicates that for peripherals in HSC domain, after reset has been asserted by writing a matching reset bit into register SRCR, it is mandatory to wait 1ms. Because it is the controller driver which can determine whether or not the controller is in HSC domain based on its compatible string, add the missing delay into the controller driver. This 1ms delay is documented on R-Car V4H and V4M, it is currently unclear whether S4 is affected as well. This patch does apply the extra delay on R-Car S4 as well.

2025-09-25pci: pcie-rcar-gen4: Assure reset occurs before DBI accessMarek Vasut
Assure the reset is latched and the core is ready for DBI access. On R-Car V4H, the PCIe reset is asynchronized and does not take effect immediately, but needs a short time to complete. In case DBI access happens in that short time, that access generates an SError. Make sure that condition can never happen, read back the state of the reset which should turn the asynchronized reset into synchronized one, and wait a little over 1ms to add additional safety margin.

2025-09-25pci: pcie-rcar-gen4: Fix inverted break condition in PHY initializationMarek Vasut
R-Car V4H Reference Manual R19UH0186EJ0130 Rev.1.30 Apr. 21, 2025 page 4581 Figure 104.3b Initial Setting of PCIEC(example), third quarter of the figure indicates that register 0xf8 should be polled until bit 18 becomes set to 1. Register 0xf8 bit 18 is 0 immediately after write to PCIERSTCTRL1 and is set to 1 in less than 1 ms afterward. The current readl_poll_timeout() break condition is inverted and returns when register 0xf8 bit 18 is set to 0, which in most cases means immediately. In case CONFIG_DEBUG_LOCK_ALLOC=y , the timing changes just enough for the first readl_poll_timeout() poll to already read register 0xf8 bit 18 as 1 and afterward never read register 0xf8 bit 18 as 0, which leads to timeout and failure to start the PCIe controller. Fix this by inverting the poll condition to match the reference manual initialization sequence. Signed-off-by: Marek Vasut <[email protected]>

2025-07-14pci: Assign a default value on reads on errorAndrew Goodbody
Many callers of PCI read functions do not check the return value for error before using the variable that should contain the value read were there not to be an error. However in the error case this variable is never assigned to and so will contain uninitialised data.

Add R-Car Gen4 PCIe controller support for host mode. This controller is based on Synopsys DesignWare PCIe. However, this particular controller has a number of vendor-specific registers, and as such, requires initialization code, including PHY firmware loading. The PHY firmware loading is implemented in an entirely generic manner, by calling a firmware loading script, which the user can configure in a way they require. This provides the user with flexibility of loading the PCIe firmware from whichever storage device they need to load it from. Signed-off-by: Marek Vasut <[email protected]>

2025-03-12pci_auto: Downgrade prefetch if necessaryPatrick Rudolph
Legacy PCI devices, like qemu's Bochs VGA device, are allowed to have prefetchable 32-bit BARs, while PCIe devices are not allowed to have 32-bit prefetchable BARs. Typically prefetchable BARs are 64-bit and typically the prefetch MMIO window is also 64-bit and placed above 4GiB, as it's the case on qemu sbsa-ref. Currently the U-Boot code assumes that prefetchable BARs are 64-bit BARs and always tries to assign them into the prefetch MMIO window. When a 32-bit BAR is marked as prefetch, but the prefetch area is not within the first 4GiB of the address space, then downgrade the BAR and place it in the non-prefetch MMIO window. For prefetch BARs there's no downside on being placed in non prefetch MMIO areas, besides the possible slower performance when a driver tries to map it Write-Combine. TEST: Fixes pci_auto on QEMU sbsa-ref fails to autoconfigure BAR0. Signed-off-by: Patrick Rudolph <[email protected]>
2025-01-23pci: mediatek: add support for multiple ports in mediatek pcie gen3 driverWeijie Gao
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_.

2024-10-27Merge patch series "Implement ACPI on aarch64"Tom Rini
Patrick Rudolph <[email protected]> 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.
