arm64: Enable RW, RX and RO mappings for the relocated binary

2025-03-14T11:37:54Z

Now that we have everything in place switch the page permissions for .rodata, .text and .data just after we relocate everything in top of the RAM. Unfortunately we can't enable this by default, since we have examples of U-Boot crashing due to invalid access. This usually happens because code defines const variables that it later writes. So hide it behind a Kconfig option until we sort it out. It's worth noting that EFI runtime services are not covered by this patch on purpose. Since the OS can call SetVirtualAddressMap which can relocate runtime services, we need to set them to RX initially but remap them as RWX right before ExitBootServices.

sandbox: remap memory load addresses

2025-03-08T14:27:22Z

The existing memory layout places the bloblist at 0xb000 and the fdt at 0x100, resulting in a 0xaf00 size constraint for the fdt. This constraint has been reached. Lets modify the layout by moving the bloblist to 0x100, device tree to 0x1000 and placing early memory allocation after pre-console buffer at 0xf4000. This should guarantee sufficient memory allocation for future expansion. Signed-off-by: Svyatoslav Ryhel

bloblist: kconfig for mandatory incoming standard passage

2025-02-20T00:49:36Z

In previous commit, incoming standard passage is used by default when initializing the bloblist, so explicitly BLOBLIST_PASSAGE is no more needed. Rename it as BLOBLIST_PASSAGE_MANDATORY to determine the behaviors when an incoming transfer list does not exist or is invalid. When it is selected, incoming standard passage is mandatory and U-Boot will report an error when a valid incoming transfer list is missing. Signed-off-by: Raymond Mao

bloblist: add support for CONFIG_BLOBLIST_PASSAGE

2025-02-12T00:08:58Z

When the configuration option CONFIG_BLOBLIST_PASSAGE is selected, the bloblist present in the incoming standard passage is utilised in-place. There is no need to specify the size of the bloblist as the system automatically detects it using the header information. Signed-off-by: Harrison Mutai

bloblist: Make BLOBLIST_ALLOC the default

2025-01-22T21:58:03Z

We want to encourage people to use an allocated bloblist since it is more flexible than a fixed one. Make this the default, being sure not to change existing users. The unit tests require BLOBLIST_FIXED so add a dependency in the Makefile to avoid build errors. All sandbox builds require BLOBLIST_FIXED so make that the default for sandbox.

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.
