This prevented common, target-agnostic code like the SMMU model from using these definitions without triggering "cpu.h included from common code" errors. To resolve this, this commit introduces a new, lightweight header, include/hw/arm/arm-security.h, which is safe for inclusion by common code. The following change was made: - The ARMSecuritySpace enum and the arm_space_is_secure() and arm_secure_to_space() helpers have been moved from target/arm/cpu.h to the new hw/arm/arm-security.h header. This refactoring decouples the security state definitions from the core CPU implementation, allowing common hardware models to correctly handle security states without pulling in heavyweight, target-specific headers.
