All the uclass functions for finding a device end up creating a uclass
if it doesn't exist. Add a function which instead returns NULL in this
case.
This is useful when in the 'unbind' path, since we don't want to undo
any unbinding which has already happened.

Unlike linked lists, it is inefficient to remove items from an alist,
particularly if it is large. If most items need to be removed, then the
time-complexity approaches O(n2).
Provide a way to do this efficiently, by working through the alist once

Heinrich Schuchardt <[email protected]> says:
With this series opendir, readdir, closedir are implemented for ext4.
These functions are needed for the UEFI sub-system to interact with
the ext4 file system.
To reduce code growth the functions are reused to implement the ls
command for ext4.
A memory leak in ext4fs_exists is resolved.
ext4fs_iterate_dir is simplified by removing a redundant pointer copy.

The SPI_ADVANCE description does not explain what the switch does.
It does not have anything to do with any advanced functionality, it
only gates off support for stacked and parallel SPI NORs. Rename the
Kconfig symbol, update description, and move it right next to Xilinx
hardware as it seems to be specific to this hardware. Make sure the
symbol is also protected by if DM_SPI in Kconfig.

lmb_alloc_flags() & lmb_alloc_base_flags() are just a wrappers for
_lmb_alloc_base(). Since the only difference is the max address of the
allowed allocation which _lmb_alloc_base() already supports with the
LMB_ALLOC_ANYWHERE flag, remove one of them.
Keep the lmb_alloc_base_flags() which also prints an error on failures
and adjust efi_allocate_pages() to only use one of them.

Due to the removal of weak functions in 7d6cee2cd0 ("cmd: cache: Remove
weak function"), U-Boot fails to compile after updating to v2024.10 for
mediatek target in OpenWrt with GCC-14 with error:
cmd/cache.c: In function 'do_dcache':
cmd/cache.c:57:25: error: implicit declaration of function
'noncached_set_region' [-Wimplicit-function-declaration]
Thus, provide a prototype in include/cpu_func.h to fix a build
error in cmd/cache.c, since related prototypes are also located there.
The issue occurred after the update of uboot-mediatek in OpenWrt to
v2024.10, in combination with GCC-14 toolchain. It was reported and
discussed in https://github.com/openwrt/openwrt/issues/16697, and

Due to new DDR size introduction, the current logic of determining the
DDR size is not able to get the correct size.
Instead, the DDR size is determined by the FSBL(SEBOOT) then passed to
u-boot through the scratchpad info.
The SEBoot version must be >= D/V01.04.01.02 to support this change.
Also now for some variants, the DDR size may > 2GB, so borrow some code
from the TI evm to iot2050 to support more than 2GB DDR.

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.

On Arm platforms that use ACPI they cannot rely on the "spin-table"
CPU bringup usually defined in the FDT. Thus implement the
'ACPI Multi-processor Startup for ARM Platforms', also referred to as
'ACPI parking protocol'.
The ACPI parking protocol works similar to the spin-table mechanism, but
the specification also covers lots of shortcomings of the spin-table
implementations.
Every CPU defined in the ACPI MADT table has it's own 4K page where the
spinloop code and the OS mailbox resides. When selected the U-Boot board
code must make sure that the secondary CPUs enter u-boot after relocation
as well, so that they can enter the spinloop code residing in the ACPI
parking protocol pages.
The OS will then write to the mailbox and generate an IPI to release the
CPUs from the spinloop code.
For now it's only implemented on ARMv8, but can easily be extended to
other platforms, like ARMv7.

Add support for Arm sbsa [1] v0.3+ that is supported by QEMU [2].
Unlike other Arm based platforms the machine only provides a minimal
FDT that contains number of CPUs, ammount of memory and machine-version.
The boot firmware has to provide ACPI tables to the OS.
Due to this design a full DTB is added here as well that allows U-Boot's
driver to properly function. The DTB is appended at the end of the U-Boot
image and will be merged with the QEMU provided DTB.
In addition provide documentation how to use, enable binman to fabricate both
ROMs that are required to boot and add ACPI tables to make it full compatible
to the EDK2 reference implementation.
The board was tested using Fedora 40 Aarch64 Workstation. It's able
to boot from USB and AHCI or network.
Tested and found working:
- serial
- PCI
- xHCI
- Bochs display
- AHCI
- network using e1000e
- CPU init
- Booting Fedora 40

Support reading the "interrupts" property from the devicetree in case
the "interrupts-extended" property isn't found. As the "interrupts"
property is commonly used, this allows to parse all existing FDT and
makes irq_get_by_index() more useful.
The "interrupts" property doesn't contain a phandle as "interrupts-extended"
does, so implement a new method to locate the interrupt-parent called
irq_get_interrupt_parent().
