Currently, in the linkcmds file, all the .text sections are located together because of the *(.text*) input section description.  The envisaged memory map goes like this:

Take a look at this page:

http://sourceware.org/binutils/docs-2.19/ld/Input-Section-Basics.html#Input-Section-Basics

and specifically the part on including sections for a specific file. 
Maybe that can help. The complication comes with other data in the flash 
or ROM memory that is part of the application but not at the separated 
address

Why do want to keep the application code separate ?
