		stored at the beginning of the FLASH.  It should be
		used when the (hard reset) IP and boot memory space
		are both mapped to address 0.

		The HIGH option selects the memory layout for an image
		stored in the last Megabyte of FLASH.  It should be
		used when the (hard reset) IP maps the interrupt
		vector base address to 0xFFF00000 and the boot memory
		space to the last 32 Megabytes of FLASH.

		The RAM option is a hack used to place the ROM image
		in RAM in order to simplify the development of a ROM
		monitor by using the existing ROM monitor to load it
		into RAM, but pretend like it is in ROM."
