This option selects which memory layout file should be

The LOW option selects the memory layout for an image
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."
