Detailed Description

Normal-world nRF5340 hooks for the TrustZone API.

Provides the NS-side wake mechanism that the secure side pends via tz_arch_signal_ns. EGU0_IRQn is borrowed as a software-only doorbell: the EGU peripheral itself is unused, only its NVIC slot.

tz_arch_init_ns_signal()

void tz_arch_init_ns_signal

(

void

)

Initialize the platform-specific mechanism that delivers secure-side wake-up requests to the normal world.

Called once during normal-world TrustZone initialization. Weakly defined as a no-op so platforms without a wake mechanism still link; in that case secure-only events do not autonomously wake the normal world.
