This patch leverages the alternative mechanism to dynamically optimize
bitops (including __ffs, __fls, ffs, fls) with Zbb instructions. When
Zbb ext is not supported by the runtime CPU, legacy implementation is
used. If Zbb is supported, then the optimized variants will be selected
via alternative patching.
The legacy bitops support is taken from the generic C implementation as
fallback.
If the parameter is a build-time constant, we leverage compiler builtin to
calculate the result directly, this approach is inspired by x86 bitops
implementation.
EFI stub runs before the kernel, so alternative mechanism should not be
used there, this patch introduces a macro NO_ALTERNATIVE for this purpose.

As mentioned in Documentation/process/coding-style.rst:
In source files, separate functions with one blank line. If the function
is exported, the **EXPORT** macro for it should follow immediately after
the closing function brace line.
So inline with guideline move zynqmp_pm_feature export symbol after its
definition.

The Qualcomm SMC an QSEECOM drivers are moved into a "qcom"
subdirectory, to declutter the base directory. Missing include guards
are added to the qseecom header file. Unneded extern specifiers are
removed from the scm call wrappers.
__counted_by is added to the apr_rx_buf structure, in the APR driver.
Lastly in the pmic_glink driver the pmic_glink drm_bridge type is
corrected to DisplayPort, over the incorrect "USB" value. The return
values are added to error prints for the various typec set() calls.

Michael reported soft lockups on a system that has unaccepted memory.
This occurs when a user attempts to allocate and accept memory on
multiple CPUs simultaneously.
The root cause of the issue is that memory acceptance is serialized with
a spinlock, allowing only one CPU to accept memory at a time. The other
CPUs spin and wait for their turn, leading to starvation and soft lockup
reports.
To address this, the code has been modified to release the spinlock
while accepting memory. This allows for parallel memory acceptance on
multiple CPUs.
A newly introduced "accepting_list" keeps track of which memory is
currently being accepted. This is necessary to prevent parallel
acceptance of the same memory block. If a collision occurs, the lock is
released and the process is retried.
Such collisions should rarely occur. The main path for memory acceptance
is the page allocator, which accepts memory in MAX_ORDER chunks. As long
as MAX_ORDER is equal to or larger than the unit_size, collisions will
never occur because the caller fully owns the memory block being
accepted.
Aside from the page allocator, only memblock and deferered_free_range()
accept memory, but this only happens during boot.
The code has been tested with unit_size == 128MiB to trigger collisions
and validate the retry codepath.

Qualcomm driver updates for v6.7
This introduces partial support for the Qualcomm Secure Execution
Environment SCM interface, and uses this to implement EFI variable
access on the Windows On Snapdragon devices (for now).
The 32/64-bit calling convention detector of the SCM interface is
updated to not choose 64-bit convention when Linux is 32-bit. The
"extern" specifier is dropped from the interface include file.
The LLCC driver gains support for carrying configuration for multiple
different system/DDR configurations for a given platform, and selecting
between them. Support for Q[DR]U1000 is added to the driver.
All exported symbols are transitioned to EXPORT_SYMBOL_GPL().
The platform_drivers in the Qualcomm SoC are transitioned to the
void-returning remove_new implementation.
The rmtfs memory driver gains support for leaving guard pages around the
used area, to avoid issues if the allocation happens to be placed
adjacent to another protected memory region.
The socinfo driver gains knowledge about IPQ8174, QCM6490, SM7150P and
various PMICs used together with SM8550.

After the vga console no longer relies on global screen_info, there are
only two remaining use cases:
- on the x86 architecture, it is used for multiple boot methods
(bzImage, EFI, Xen, kexec) to commucate the initial VGA or framebuffer
settings to a number of device drivers.
- on other architectures, it is only used as part of the EFI stub,
and only for the three sysfb framebuffers (simpledrm, simplefb, efifb).
Remove the duplicate data structure definitions by moving it into the
efi-init.c file that sets it up initially for the EFI case, leaving x86
as an exception that retains its own definition for non-EFI boots.
The added #ifdefs here are optional, I added them to further limit the
reach of screen_info to configurations that have at least one of the
users enabled.

To prepare for completely separating the VGA console screen_info from
the one used in EFI/sysfb, rename the vgacon instances and make them
local as much as possible.
ia64 and arm both have confurations with vgacon and efi, but the contents
never overlaps because ia64 has no EFI framebuffer, and arm only has
vga console on legacy platforms without EFI. Renaming these is required
before the EFI screen_info can be moved into drivers/firmware.
The ia64 vga console is actually registered in two places from
setup_arch(), but one of them is wrong, so drop the one in pcdp.c and
fix the one in setup.c to use the correct conditional.
x86 has to keep them together, as the boot protocol is used to switch
between VGA text console and framebuffer through the screen_info data.

Arm FF-A updates for v6.7
The main addition is the initial support for the notifications and
memory transaction descriptor changes added in FF-A v1.1 specification.
The notification mechanism enables a requester/sender endpoint to notify
a service provider/receiver endpoint about an event with non-blocking
semantics. A notification is akin to the doorbell between two endpoints
in a communication protocol that is based upon the doorbell/mailbox
mechanism.
The framework is responsible for the delivery of the notification from
the ender to the receiver without blocking the sender. The receiver
endpoint relies on the OS scheduler for allocation of CPU cycles to
handle a notification.
OS is referred as the receiver’s scheduler in the context of notifications.
The framework is responsible for informing the receiver’s scheduler that
the receiver must be run since it has a pending notification.
The series also includes support for the new format of memory transaction
descriptors introduced in v1.1 specification.
Apart from the main additions, it includes minor fixes to re-enable FF-A
drivers usage of 32bit mode of messaging and kernel warning due to the
missing assignment of IDR allocation ID to the FFA device. It also adds
emitting 'modalias' to the base attribute of FF-A devices.

Arm SCMI updates for v6.7
Main additions this time include:
1. SCMI v3.2 clock configuration support:
This helps to retrieve the enabled state of a clock as well as allow
to set OEM specific clock configurations.
2. Support for generic performance scaling(DVFS):
The current SCMI DVFS support is limited to the CPUs in the kernel.
This extension enables it to used for all kind of devices and not
only for the CPUs. It updates the SCMI cpufreq to utilize the power
domain bindings. It also adds a more generic SCMI performance domain
based on the genpd framework that as be used for all the non-CPU
devices.
3. Extend the generic performance scaling(DVFS) support for firmware
driver OPPs:
Consumer drivers for devices that are attached to the SCMI performance
domain can't make use of the current OPP library to scale performance
as the OPPs are firmware driven and often obtained from the firmware
rather than the device tree. These changes extend the generic OPP
and genpd PM domain frameworks to identify and utilise these firmware
driven OPPs.
4. SCMI v3.2 clock parent support:
This enables the support for discovering and changing parent clocks
and extending the SCMI clk driver to use the same.
5. Qualcom SMC/HVC transport support:
The Qualcomm virtual platforms require capability id in the hypervisor
call to identify which doorbell to assert when supporting multiple
SMC/HVC based SCMI transport channels. Extra parameter is added to
support the same and the same is obtained at the fixed address in the
shared memory which is initialised by the firmware.
6. Move the existing SCMI power domain driver under drivers/pmdomain
Apart from the above main changes, it also include couple of minor fixes
and cosmetic reworks.

Add suspend hook and a 'suspended' field in the 'struct tegra_bpmp'
to mark if BPMP is suspended. Also, add a 'flags' field in the
'struct tegra_bpmp_message' whose 'TEGRA_BPMP_MESSAGE_RESET' bit can be
set from the Tegra MC driver to signal that the reset of BPMP IPC
channels is required before sending MRQ to the BPMP FW. Together both
the fields allow us to handle any requests that might be sent too soon
as they can cause hang during system resume.
One case where we see BPMP requests being sent before the BPMP driver
has resumed is the memory bandwidth requests which are triggered by
onlining the CPUs during system resume. The CPUs are onlined before the
BPMP has resumed and we need to reset the BPMP IPC channels to handle
these requests.
The additional check for 'flags' is done to avoid any un-intended BPMP
IPC reset if the tegra_bpmp_transfer*() API gets called during suspend
sequence after the BPMP driver is suspended.

identify the doorbell from the VM's capability namespace, similar

The hypervisor, in addition to the function-id, expects the capability-id

The capability-id is allocated by the hypervisor on bootup and is stored in

The function documentation for devm_rpi_firmware_get() was missing
a description for the dev parameter.
Provide it and clear the warning produced here.

Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.

With quite a few v1.1 features supported, we can bump the driver version
to v1.1 now.

Update memory transaction descriptor structure to accommodate couple of
new entries in v1.1 which were previously marked reserved and MBZ(must
be zero).
It also removes the flexible array member ep_mem_access in the memory
transaction descriptor structure as it need not be at fixed offset.
Also update ffa_mem_desc_offset() accessor to handle both old and new
formats of memory transaction descriptors.
The updated ffa_mem_region structure aligns with new format in v1.1 and
hence the driver/user must take care not to use members beyond and
including ep_mem_offset when using the old format.

In preparation to add support to the new memory transaction descriptor,
the ep_mem_access member needs to be removed and hence even the macro
COMPOSITE_OFFSET(). Let us switch to using the new ffa_mem_desc_offset()
accessor in ffa_setup_and_transmit().
This will enable adding the support for new format transparently without
any changes here again.

SCMI v3.2 spec introduces CLOCK_POSSIBLE_PARENTS_GET, CLOCK_PARENT_SET
and CLOCK_PARENT_GET. Add support for these to enable clock parents
and use them in the clock driver.

The computation of endpoint memory access descriptor's composite memory
region descriptor offset is using COMPOSITE_CONSTITUENTS_OFFSET which is
unnecessary complicated. Composite memory region descriptor always follow
the endpoint memory access descriptor array and hence it is computed
accordingly. COMPOSITE_CONSTITUENTS_OFFSET is useless and wrong for any
input other than endpoint memory access descriptor count.
Let us drop the usage of COMPOSITE_CONSTITUENTS_OFFSET to simplify the
computation of total transmit and fragment length in the memory
transactions.

With all the necessary plumbing in place, let us add handling the
notifications as part of schedule receiver interrupt handler. In order
to do so, we need to just register scheduling callback on behalf of the
driver partition.

The framework provides an interface to the sender endpoint to specify
the notification to signal to the receiver endpoint. A sender signals
a notification by requesting its partition manager to set the
corresponding bit in the notifications bitmap of the receiver.
Expose the ability to send a notification to another partition.
