// Author(s):     jlarmour

// Contributors:  jlarmour

// Date:          1999-01-21

// 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,

//                which will allow you to take complete control after the

//                HAL initialization
