CONFIG_ARM_CUSTOM_INTERRUPT_CONTROLLER
(No prompt – not directly user assignable.)
Type: bool
Help
This option indicates that the ARM CPU is connected to a custom (i.e.
non-GIC) interrupt controller.
A number of Cortex-A and Cortex-R cores (Cortex-A5, Cortex-R4/5, ...)
allow interfacing to a custom external interrupt controller and this
option must be selected when such cores are connected to an interrupt
controller that is not the ARM Generic Interrupt Controller (GIC).
When this option is selected, the architecture interrupt control
functions are mapped to the SoC interrupt control interface, which is
implemented at the SoC level.
N.B. This option is only applicable to the Cortex-A and Cortex-R
family cores. The Cortex-M family cores are always equipped with
the ARM Nested Vectored Interrupt Controller (NVIC).
