# ARM architecture configuration options # Copyright (c) 2014-2015 Wind River Systems, Inc. # SPDX-License-Identifier: Apache-2.0 menu "ARM Options" depends on ARM config ARCH default "arm" config ARM64 bool select 64BIT config CPU_CORTEX bool help This option signifies the use of a CPU of the Cortex family. config ARM_CUSTOM_INTERRUPT_CONTROLLER bool depends on !CPU_CORTEX_M 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). if !ARM64 rsource "core/aarch32/Kconfig" endif if ARM64 rsource "core/aarch64/Kconfig" endif endmenu |
