Use a function to obtain the device EFI filename, so that we can control
how sandbox behaves.

menu: add support to check if menu needs to be reprinted

2024-11-04T22:41:38+00:00

This patch adds a new callback named need_reprint for menu.
The need_reprint will be called before printing the menu. If the
callback exists and returns FALSE, menu printing will be canceled.

This is very useful if the menu was not changed. It can save time
for serial-based menu to handle more input data.

lmb: Fix lmb_add_region_flags() return codes and testing

2024-10-29T22:17:47+00:00

The function description says this should return 0 or -1 on failures.
When regions coalesce though this returns the number of coalescedregions
which is confusing and requires special handling of the return code.
On top of that no one is using the number of coalesced regions.

So let's just return 0 on success and adjust our selftests accordingly

fdt: lmb: add reserved regions as no-overwrite

2024-10-29T18:09:55+00:00

The boot_fdt_add_mem_rsv_regions() function reserves the memreserve and
reserved-memory regions. These regions are being set with the LMB_NONE
flag which allows overwriting and re-using the regions. This was fine
earlier when the LMB memory map was local and not enforced
globally. But that is no longer the case. Mark these regions as
LMB_NOOVERWRITE so that they cannot be used.

Merge patch series "Implement ACPI on aarch64"

2024-10-28T00:44:13+00:00

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.

serial: serial_pl01x: Implement .getinfo() for PL01

When ACPI is enabled on arm it will use the getinfo function to fill
the SPCR ACPI table.
