Change the logging of each algorithm from info level to debug level.
On the original devices supported by this code there were typically only
one or two algorithms in a firmware and one or two DSPs so this logging
only used a small number of log lines.
However, for the latest devices there could be 30-40 algorithms in a
firmware and 8 DSPs being loaded in parallel, so using 300+ lines of log
for information that isn't particularly important to have logged.

Kyril reports that crashkernels fail to work on confidential VMs that
rely on the unaccepted memory table, and this appears to be caused by
the fact that it is not considered part of the set of firmware tables
that the crashkernel needs to map.
This is an oversight, and a result of the use of the EFI_LOADER_DATA
memory type for this table. The correct memory type to use for any
firmware table is EFI_ACPI_RECLAIM_MEMORY (including ones created by the
EFI stub), even though the name suggests that is it specific to ACPI.
ACPI reclaim means that the memory is used by the firmware to expose
information to the operating system, but that the memory region has no
special significance to the firmware itself, and the OS is free to
reclaim the memory and use it as ordinary memory if it is not interested
in the contents, or if it has already consumed them. In Linux, this
memory is never reclaimed, but it is always covered by the kernel direct
map and generally made accessible as ordinary memory.
On x86, ACPI reclaim memory is translated into E820_ACPI, which the
kexec logic already recognizes as memory that the crashkernel may need
to to access, and so it will be mapped and accessible to the booting
crash kernel.

Alexandre Ghiti <alexghiti@rivosinc.com> says:
The following KASLR implementation allows to randomize the kernel mapping:
- virtually: we expect the bootloader to provide a seed in the device-tree
- physically: only implemented in the EFI stub, it relies on the firmware to
provide a seed using EFI_RNG_PROTOCOL. arm64 has a similar implementation
hence the patch 3 factorizes KASLR related functions for riscv to take
advantage.
The new virtual kernel location is limited by the early page table that only
has one PUD and with the PMD alignment constraint, the kernel can only take
< 512 positions.

We can now use arm64 functions to handle the move of the kernel physical
mapping: if KASLR is enabled, we will try to get a random seed from the
firmware, if not possible, the kernel will be moved to a location that
suits its alignment constraints.

firmware drivers.
On the soc driver side, the updates are mostly cleanups across a
number of Arm platforms. On driver for loongarch adds power management
for DT based systems, another driver is for HiSilicon's Arm server
chips with their HCCS system health interface.

Instead of bypassing the kernel's adaptation layer for performing EFI
runtime calls, wire up ACPI PRM handling into it. This means these calls
can no longer occur concurrently with EFI runtime calls, and will be
made from the EFI runtime workqueue. It also means any page faults
occurring during PRM handling will be identified correctly as
originating in firmware code.

Avoid duplicating the EFI arch setup and teardown routine calls numerous

__efi_call_virt() exists as an alternative for efi_call_virt() for the
sole reason that ResetSystem() returns void, and so we cannot use a call
to it in the RHS of an assignment.
Given that there is only a single user, let's drop the macro, and expand
it into the caller. That way, the remaining macro can be tightened
somewhat in terms of type safety too.
Note that the use of typeof() on the runtime service invocation does not
result in an actual call being made, but it does require a few pointer
types to be fixed up and converted into the proper function pointer
prototypes.

Qualcomm driver updates for v6.6
Compatible and clock handling in the Qualcomm SCM driver is cleaned up,
together with a couple stylistic cleanups and transition to mark
exported symbols GPL only.
An abstraction for the RPM subsystem is introduced, to make align the
structure of the SMD and GLINK nodes thereof with the structure when a
remoteproc is involved. This is done to facilitate associating
additional entities with the RPM subsystem.
The qmp_send() API is modified to not expose hardware requirements onto
the client drivers, and then further extended to allow command
formatting directly in the API, to facilitate this typical use case.
In the Qualcomm Command DB driver, NUL characters previously included in
identifiers are dropped from the debugfs, to facilitate scripting.
The thresholds of the BWMON driver are simplified to avoid hard coded
starting values.
The OCMEM driver is updated with some cleanups and fixes, and addition
of MSM8226 support.
PMIC_GLINK gains support for retimer switches, safe mode is selected
when the cable is disconnected from altmode and the same is enabled for
SM8550.
An off-by-one string length check is corrected in the QMI encoder
decoder library.
The RPMh tracepoints are extended to include the state of the request,
to provide needed context in the traced events.
The series from Ulf creating a genpd framework is integrated, to
facilitate the other changes to the cpr, rpmpd and rpmhpd driver.
SDX75 support is added to the rpmhpd driver, and the rpmpd driver is
extended with the same sync_state logic found in the rpmhpd driver.
The socinfo driver gains knowledge about SM4450 and SM7125, the IPQ5019
platform is dropped.
Clock handling in the GSBI driver is cleaned up with the use of
devm_clk_get_enabled().
The list of VMIDs defined for the SCM assign memory interface is
extended.

efi_queue_work() is a macro that implements the non-trivial manipulation

The current code that marshalls the EFI runtime call arguments to hand
them off to a async helper does so in a type unsafe and slightly messy
manner - everything is cast to void* except for some integral types that
are passed by reference and dereferenced on the receiver end.
Let's clean this up a bit, and record the arguments of each runtime
service invocation exactly as they are issued, in a manner that permits
the compiler to check the types of the arguments at both ends.

Only the arch_efi_call_virt() macro that some architectures override
needs to be a macro, given that it is variadic and encapsulates calls
via function pointers that have different prototypes.
The associated setup and teardown code are not special in this regard,
and don't need to be instantiated at each call site. So turn them into
ordinary C functions and move them out of line.

Before adding a new FW control, its name is checked against
existing controls list. But the string length in strncmp used
to compare controls names is taken from the list, so if beginnings
of the controls are matching, then the new control is not created.
For example, if CAL_R control already exists, CAL_R_SELECTED
is not created.
The fix is to compare string lengths as well.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Record SCU wakeup interrupt in /sys/power/pm_wakeup_irq
The user can further identify the exact wakeup source by using the
following interface:
cat /sys/firmware/scu_wakeup_source/wakeup_src
The above will print the wake groups and the irqs that could have
contributed to waking up the kernel. For example if ON/OFF button was the
wakeup source:
cat /sys/firmware/scu_wakeup_source/wakeup_src
Wakeup source group = 3, irq = 0x1
The user can refer to the SCFW API documentation to identify all the
wake groups and irqs.

Use blocking_notifier_chain instead of atomic_notifier_chain, otherwise
there will be RCU complaint, because unregister/register_virtio_device()
will issue mbox message.
mbox_send_message() is blocking again after received M4 partition reset.

The bare metal decompressor code was never really intended to run in a
hosted environment such as the EFI boot services, and does a few things
that are becoming problematic in the context of EFI boot now that the
logo requirements are getting tighter: EFI executables will no longer be
allowed to consist of a single executable section that is mapped with
read, write and execute permissions if they are intended for use in a
context where Secure Boot is enabled (and where Microsoft's set of
certificates is used, i.e., every x86 PC built to run Windows).
To avoid stepping on reserved memory before having inspected the E820
tables, and to ensure the correct placement when running a kernel build
that is non-relocatable, the bare metal decompressor moves its own
executable image to the end of the allocation that was reserved for it,
in order to perform the decompression in place. This means the region in
question requires both write and execute permissions, which either need
to be given upfront (which EFI will no longer permit), or need to be
applied on demand using the existing page fault handling framework.
However, the physical placement of the kernel is usually randomized
anyway, and even if it isn't, a dedicated decompression output buffer
can be allocated anywhere in memory using EFI APIs when still running in
the boot services, given that EFI support already implies a relocatable
kernel. This means that decompression in place is never necessary, nor
is moving the compressed image from one end to the other.
Since EFI already maps all of memory 1:1, it is also unnecessary to
create new page tables or handle page faults when decompressing the
kernel. That means there is also no need to replace the special
exception handlers for SEV. Generally, there is little need to do
any of the things that the decompressor does beyond
- initialize SEV encryption, if needed,
- perform the 4/5 level paging switch, if needed,
- decompress the kernel
- relocate the kernel
So do all of this from the EFI stub code, and avoid the bare metal
decompressor altogether.

Before refactoring the EFI stub boot flow to avoid the legacy bare metal
decompressor, duplicate the SNP feature check in the EFI stub before
handing over to the kernel proper.
The SNP feature check can be performed while running under the EFI boot
services, which means it can force the boot to fail gracefully and
return an error to the bootloader if the loaded kernel does not
implement support for all the features that the hypervisor enabled.

x86 will need to limit the kernel memory allocation to the lowest 512
MiB of memory, to match the behavior of the existing bare metal KASLR
physical randomization logic. So in preparation for that, add a limit
parameter to efi_random_alloc() and wire it up.

Currently, the EFI stub relies on DXE services in some cases to clear
non-execute restrictions from page allocations that need to be
executable. This is dodgy, because DXE services are not specified by
UEFI but by PI, and they are not intended for consumption by OS loaders.
However, no alternative existed at the time.
Now, there is a new UEFI protocol that should be used instead, so if it
exists, prefer it over the DXE services calls.

In preparation for updating the EFI stub boot flow to avoid the bare
metal decompressor code altogether, implement the support code for
switching between 4 and 5 levels of paging before jumping to the kernel
proper.
Reuse the newly refactored trampoline that the bare metal decompressor
uses, but relies on EFI APIs to allocate 32-bit addressable memory and
remap it with the appropriate permissions. Given that the bare metal
decompressor will no longer call into the trampoline if the number of
paging levels is already set correctly, it is no longer needed to remove
NX restrictions from the memory range where this trampoline may end up.

The so-called EFI handover protocol is value-add from the distros that
permits a loader to simply copy a PE kernel image into memory and call
an alternative entrypoint that is described by an embedded boot_params
structure.
Most implementations of this protocol do not bother to check the PE
header for minimum alignment, section placement, etc, and therefore also
don't clear the image's BSS, or even allocate enough memory for it.
Allocating more memory on the fly is rather difficult, but at least
clear the BSS region explicitly when entering in this manner, so that
the EFI stub code does not get confused by global variables that were
not zero-initialized correctly.
When booting in mixed mode, this BSS clearing must occur before any
global state is created, so clear it in the 32-bit asm entry point.

Now that the EFI entry code in assembler is only used by the optional
and deprecated EFI handover protocol, and given that the EFI stub C code
no longer returns to it, most of it can simply be dropped.
While at it, clarify the symbol naming, by merging efi_main() and
efi_stub_entry(), making the latter the shared entry point for all
different boot modes that enter via the EFI stub.
The efi32_stub_entry() and efi64_stub_entry() names are referenced
explicitly by the tooling that populates the setup header, so these must
be retained, but can be emitted as aliases of efi_stub_entry() where
appropriate.
