[PATCH 1/7] m68k: Implement a default flush_dcache_all
by Tom Rini 10 Sep '24

10 Sep '24

Implement a weak default version of flush_dcache_all which is based on the ARM default, which is to flush the entire range via flush_dcache_range(...).

[PATCH 0/3] cmd: clk: simplify clk command
by Heinrich Schuchardt 10 Sep '24

10 Sep '24

The clk command cannot provide useful output without a clock driver. So let it depend on CONFIG_CLK. Fix the Kconfig description of the command. As with the series the clk command is only built if CONFIG_CLK=y we can remove some #ifdefs. Enabling the clk command on the sandbox will allow us to write tests for it.

[PATCH v2 00/28] Implement ACPI on aarch64
by Patrick Rudolph 09 Sep '24

09 Sep '24

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 Please note that the current implementation still requires a DTB to be provided to U-Boot and that the DTB is used within U-Boot to load drivers, to disable/enable certain hardware blocks in ACPI. The DTB is not passed to the OS when using the bootefi cmd. 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 real hardware, but works in QEMU. - PCI on RPI4 isn't working on real hardware since the pcie_brcmstb Linux kernel module doesn't support ACPI yet.

[PATCH v2] cmd: sf: prevent overwriting the reserved memory
by Prasad Kummari 09 Sep '24

09 Sep '24

Added LMB API to prevent SF command from overwriting reserved memory areas. The current SPI code does not use LMB APIs for loading data into memory addresses. To resolve this, LMB APIs were added to check the load address of an SF command and ensure it does not overwrite reserved memory addresses. Similar checks are used in TFTP, serial load, and boot code to prevent overwriting reserved memory. Signed-off-by: Prasad Kummari <prasad.kummari(a)amd.com> --- Changes in V2: - Rebased the code changes on top of the next branch.
