123 *
124 * In case the BSP enabled the MPC55XX_ENABLE_START_PROLOGUE option, then this
125 * function will be called directly after the Boot Assist Module (BAM) jumped
126 * to the start entry defined by the reset configuration.
127 *
128 * This function executes in the context initialized by the BAM.  There exists
129 * no valid stack pointer and the internal RAM has an invalid ECC state.
130 *
131 * The default implementation does nothing.  The application may provide its
132 * own implementation.
