fix(gicv3): map generic interrupt type to GICv3 group
The generic interrupt controller identifies an interrupt based on its
type whereas the GIC uses the notion of groups to identify an
interrupt.
fix(gicv3): map generic interrupt type to GICv3 group
The generic interrupt controller identifies an interrupt based on its
type whereas the GIC uses the notion of groups to identify an
interrupt.
Currently, they are used interchangeably in GICv3 driver. It did not
cause any functional issues since the matching type and group had the
same value for corresponding macros. This patch makes the necessary
fixes.
The generic interrupt controller APIs, such as
plat_ic_set_interrupt_type map interrupt type to interrupt group
supported by the GICv3 IP. Similarly, other generic interrupt
controller APIs map interrupt group to interrupt type as needed.
This patch also changes the name of the helper functions to use group
rather than type for handling interrupts.

feat(ethos-n)!: add protected NPU firmware setup
When the Arm(R) Ethos(TM)-N NPU driver is built with TZMP1 support, the
NPU should use the firmware that has been loaded into the protected
memory by BL2. The Linux Kernel NPU driver in the non-secure world is
not allowed to configure the NPU to do this in a TZMP1 build so the SiP
service will now configure the NPU to boot with the firmware in the
protected memory.
BREAKING CHANGE: The Linux Kernel NPU driver can no longer directly
configure and boot the NPU in a TZMP1 build. The API version has
therefore been given a major version bump with this change.

The SiP service for the Arm(R) Ethos(TM)-N NPU driver will now handle
setting up the NPU's event and aux control registers during the SMC
reset call.

The SiP service for the Arm(R) Ethos(TM)-N NPU driver will now handle
setting up the NPU's event and aux control registers during the SMC
reset call. The aux control register will no longer be accessible by the
non-secure world.
The API version has been given a minor bump with this change to indicate
the added functionality.

feat(ethos-n): add SMC call to get FW properties
When the Arm(R) Ethos(TM)-N NPU firmware is loaded by BL2 into protected
memory, the Linux kernel NPU driver cannot access the firmware. To still
allow the kernel driver to access some information about the firmware,
SMC calls have been added so it can check compatibility and get the
necessary information to map the firmware into the SMMU for the NPU.
The API version has been given a minor version bump with this change to
indicate the added functionality.

to make sure that an event always wakes up the NPU.

indicate that this fix is included.
