/*******************************************************************************
 * cy_wcm_shim.h — Minimal WCM type stubs for CM55 IPC service compilation.
 *
 * WiFi runs on CM33_NS only (SDHC0 PPC-protected). CM55 wifi_manager is a
 * stub returning errors. This header provides the types and constants that
 * ipc_service.c references so it compiles without the full WiFi stack.
