Currently, the framework notifications are not supported at all.
handle_notif_callbacks() doesn't handle them though it is called with
framework bitmap. Make that explicit by adding checks for the same.
Also, we need to further classify the framework notifications as Secure
Partition Manager(SPM) and NonSecure Hypervisor(NS_HYP). Extend/change
notify_type enumeration to accommodate all the 4 type and rejig the
values so that it can be reused in the bitmap enable mask macros.
While at this, move ffa_notify_type_get() so that it can be used in
notifier_hash_node_get() in the future.
No functional change.

When the firmware compatibility was handled previously in the commit
8e3f9da608f1 ("firmware: arm_ffa: Handle compatibility with different firmware versions"),
we only addressed firmware versions that have higher minor versions
compared to the driver version which is should be considered compatible
unless the firmware returns NOT_SUPPORTED.
However, if the firmware reports higher major version than the driver
supported, we need to reject it. If the firmware can work in a compatible
mode with the driver requested version, it must return the same major
version as requested.

Both the FF-A core and the bus were in a single module before the
commit 18c250bd7ed0 ("firmware: arm_ffa: Split bus and driver into distinct modules").
The arm_ffa_bus_exit() takes care of unregistering all the FF-A devices.
Now that there are 2 distinct modules, if the core driver is unloaded and
reloaded, it will end up adding duplicate FF-A devices as the previously
registered devices weren't unregistered when we cleaned up the modules.
Fix the same by unregistering all the FF-A devices on the FF-A bus during
the cleaning up of the partitions and hence the cleanup of the module.

Currently it is assumed that the firmware doesn't present the host
partition in the list of partitions presented as part of the response
to PARTITION_INFO_GET from the firmware. However, there are few
platforms that prefer to present the same in the list of partitions.
It is not manadatory but not restricted as well.
So handle the same by making sure to check the presence of the host
VM ID in the XArray partition information maintained/managed in the
driver before attempting to add it.

Currently the FF-A driver doesn't support big-endian correctly. It is
hard to regularly test the setup due to lack of test infrastructure and
tools.
In order to support full stack, we need to take small steps in getting
the support for big-endian kernel added slowly. This change fixes the
support in __ffa_partition_info_regs_get() so that the response from the
firmware are converted correctly as required. With this change, we can
enumerate all the FF-A devices correctly in the big-endian kernel if the
FFA_PARTITION_INFO_REGS_GET is supported.

(AP, AOC, ...). ACPM firmware operates on the Active Power Management
(APM) module that handles overall power activities.

communicate with each other using mailbox messages and shared memory.

UEFI 2.11 introduced EFI_MEMORY_HOT_PLUGGABLE to annotate system memory
regions that are 'cold plugged' at boot, i.e., hot pluggable memory that
is available from early boot, and described as system RAM by the
firmware.
Existing loaders and EFI applications running in the boot context will
happily use this memory for allocating data structures that cannot be
freed or moved at runtime, and this prevents the memory from being
unplugged. Going forward, the new EFI_MEMORY_HOT_PLUGGABLE attribute
should be tested, and memory annotated as such should be avoided for
such allocations.
In the EFI stub, there are a couple of occurrences where, instead of the
high-level AllocatePages() UEFI boot service, a low-level code sequence
is used that traverses the EFI memory map and carves out the requested
number of pages from a free region. This is needed, e.g., for allocating
as low as possible, or for allocating pages at random.
While AllocatePages() should presumably avoid special purpose memory and
cold plugged regions, this manual approach needs to incorporate this
logic itself, in order to prevent the kernel itself from ending up in a
hot unpluggable region, preventing it from being unplugged.
So add the EFI_MEMORY_HOTPLUGGABLE macro definition, and check for it
where appropriate.

Pull driver core and debugfs updates from Greg KH:
"Here is the big set of driver core and debugfs updates for 6.14-rc1.
Included in here is a bunch of driver core, PCI, OF, and platform rust
bindings (all acked by the different subsystem maintainers), hence the
merge conflict with the rust tree, and some driver core api updates to
mark things as const, which will also require some fixups due to new

There are also a bunch of debugfs updates from Al, and there is at
least one user that does have a regression with these, but Al is
working on tracking down the fix for it. In my use (and everyone
else's linux-next use), it does not seem like a big issue at the

Here's a short list of the things in here:
- driver core rust bindings for PCI, platform, OF, and some i/o
functions.
We are almost at the "write a real driver in rust" stage now,
depending on what you want to do.
- misc device rust bindings and a sample driver to show how to use
them
- debugfs cleanups in the fs as well as the users of the fs api for
places where drivers got it wrong or were unnecessarily doing
things in complex ways.
- driver core const work, making more of the api take const * for

Enabling a (modular) test should not silently enable additional kernel
functionality, as that may increase the attack vector of a product.
Fix this by making FW_CS_DSP_KUNIT_TEST (and FW_CS_DSP_KUNIT_TEST_UTILS)
depend on REGMAP instead of selecting it.
After this, one can safely enable CONFIG_KUNIT_ALL_TESTS=m to build
modules for all appropriate tests for ones system, without pulling in
extra unwanted functionality, while still allowing a tester to manually
enable REGMAP_BUILD and this test suite on a system where REGMAP is not
enabled by default.

Pull EFI updates from Ard Biesheuvel:
- Increase the headroom in the EFI memory map allocation created by the
EFI stub. This is needed because event callbacks called during
ExitBootServices() may cause fragmentation, and reallocation is not
allowed after that.
- Drop obsolete UGA graphics code and switch to a more ergonomic API to
traverse handle buffers. Simplify some error paths using a __free()
helper while at it.
- Fix some W=1 warnings when CONFIG_EFI=n
- Rely on the dentry cache to keep track of the contents of the
efivarfs filesystem, rather than using a separate linked list.
- Improve and extend efivarfs test cases.
- Synchronize efivarfs with underlying variable store on resume from
hibernation - this is needed because the firmware itself or another
OS running on the same machine may have modified it.
- Fix x86 EFI stub build with GCC 15.
- Fix kexec/x86 false positive warning in EFI memory attributes table
sanity check.

GCC 15 changed the default C standard version to C23, which should not
have impacted the kernel because it requests the gnu11 standard via
'-std=' in the main Makefile. However, the EFI libstub Makefile uses its
own set of KBUILD_CFLAGS for x86 without a '-std=' value (i.e., using
the default), resulting in errors from the kernel's definitions of bool,
true, and false in stddef.h, which are reserved keywords under C23.
./include/linux/stddef.h:11:9: error: expected identifier before ‘false’
11 | false = 0,
./include/linux/types.h:35:33: error: two or more data types in declaration specifiers
35 | typedef _Bool bool;
Set '-std=gnu11' in the x86 cflags to resolve the error and consistently
use the same C standard version for the entire kernel. All other
architectures reuse KBUILD_CFLAGS from the rest of the kernel, so this
issue is not visible for them.

1. Extension of the transport properties read from devicetree to support

the SCMI core while the automatic loading of vendor protocols was not.

The EFI stub implements various ways of setting the resolution of the
EFI framebuffer at boot, and this duplicates a lot of boilerplate for
iterating over the supported modes and extracting the resolution and
color depth.
Refactor this into a single helper that takes a callback, and use it for
the 'auto', 'list' and 'res' selection methods.
