I'm not sure what you mean. If you mean that you want to adjust the
memory range based on the size of the your program, then the answer is
that you can not do that using the MEMORY command. The MEMORY command
is intended for a system with different types of memory at different
addresses. If all your memory is the same, use a linker script
without the MEMORY command.
