The ARM Generic Interrupt Controller v1 (e.g. PL390) works with the
ARM Cortex-family processors.

help
The ARM Generic Interrupt Controller v2 (e.g. GIC-400) works with the
ARM Cortex-family processors.

The ARM Generic Interrupt Controller v3 (e.g. GIC-500 and GIC-600)
works with the ARM Cortex-family processors.

config GIC_SINGLE_SECURITY_STATE
bool

help
Some ARM Cortex-family processors only supports single security
state.

bool

default y if CPU_CORTEX_R52
help
Some platforms only use aff0 to match mpdir and GICR.aff. With this
enabled, we find the target redistributor by comparing the aff0 only.
config GIC_V3_ITS
bool "GIC v3 Interrupt Translation Service"
depends on GIC_V3
# ITS generates Non-secure Group 1 LPI interrupts, requiring EL1NS
select ARMV8_A_NS
select DYNAMIC_INTERRUPTS
help
Support for the optional Interrupt Translation Service used to translate
hardware interrupt from PCIe MSI messages for example. Please note
that ITS uses dynamic memory, so HEAP_MEM_POOL_SIZE should be
enough to allocate ITS tables (size is probed at runtime).
