treewide: move bi_dram[] from bd to gd

2026-06-25T00:13:24Z

Currently, the bi_dram[] information is stored in the board info structure (bd). Because bd is only valid after reserve_board(), dram_init_banksize() must be called late in the initialization process. This limitation is problematic, as it forces us to rely on a variety of bespoke functions to determine board RAM, bank memory sizes, and other early setup requirements. By moving bi_dram[] into the global data (gd), we can run it earlier. This is particularly convenient since boards define their own dram_init_banksize() routines, which do not always rely on parsing Device Tree (DT) memory nodes. Additionally, U-Boot defaults to relocating to the top of the first memory bank. While boards currently use custom functions to override this behavior, having the DRAM bank information available earlier in gd makes relocating to a different bank trivial and standardizes the process.

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.

acpi: x86: Write FADT in common code

2024-10-27T23:12:44Z

Write the FADT in common code since it's used on all architectures. Since the FADT is mandatory all SoCs or mainboards must implement the introduced function acpi_fill_fadt() and properly update the FADT. Signed-off-by: Patrick Rudolph Reviewed-by: Simon Glass Cc: Simon Glass Cc: Bin Meng

x86: cpu: Use default print_cpuinfo() for all

2024-10-18T20:10:22Z

Most of the copies of the print_cpuinfo() call the default method. Remove all of those in order to have only the default one when no `cpu` command is compiled. This also helps avoiding compiler warning, e.g.: arch/x86/cpu/tangier/tangier.c:23:5: warning: no previous prototype for ‘print_cpuinfo’ [-Wmissing-prototypes] Signed-off-by: Andy Shevchenko Reviewed-by: Simon Glass

This follows the example of RISC-V where includes directly as "gd" includes a reference to bd_info already and so the first must include the second anyhow. We then remove from all of the places which include references to "gd" an so have already. Signed-off-by: Tom Rini

acpi: use 64-bit addresses in FADT table

2024-01-07T20:45:07Z

Fields X_FIRMWAE_CTRL and X_DSDT must be 64bit wide. Convert pointers to to uintptr_t to fill these. If field X_FIRMWARE_CTRL is filled, field FIRMWARE must be ignored. If field X_DSDT is filled, field DSDT must be ignored. We should not fill unused fields.
