23.3.4.4 .dbg_excpt Section

This section reserves space for the debug exception vector. This section is only allocated if the symbol _DEBUGGER has been defined. (This symbol is defined if the -mde-bugger command line option is specified to the shell.) This section is located at the debug exception address (_DBG_EXCPT_ADDR) as specified in the processor definitions linker script and is assigned to the boot memory region (kseg1_boot_mem). The section is marked as NOLOAD as it is only intended to ensure that application code cannot be placed at locations reserved for the debug executive.
