// Purpose:       This provides generic startup code for the eCos system.
// Description:   We start the system with the entry point cyg_start()
//                which is called from the eCos HALs. This in turn invokes
//                cyg_prestart(), cyg_package_start() and cyg_user_start().
//                All these can be overriden by the user.
// Usage:         Override the defaults to use your own startup code.
//                cyg_package_start() is used to call into individual
//                packages' startup code. Alternatively leave it be and
//                use the configuration options to set the appropriate
//                compatibility environment e.g. uItron, ISO C, etc.
//                This may be automatically generated in the future.
