//  File: at91_startup.mac
//
// This file will put the AT91 in protected mode to allow debugger
// windows showing register and memory content to read the AIC controller
// without interfering with the AIC interrupt controller.
// This must be done before execution of the program to allow for the
// case when a window showing AIC content is active when the debugger starts.
// The EB55 PLL and memory controller is initialized and a REMAP
// command executed.
//
