You really should be using current version of GDB together with remote
stub that supports flash write -- in which case it will be totally transparent 
for you;-)

The current (vague) plan is to have 'debugger configuration' thing, where the 'application'
can be either binary, or a target in the build system. In the latter case, it would
be reasonable to grab as much data as possible from the build system. OTOH,
I'm not quite sure that "ROM/RAM" option is a standard thing in any build system
nowdays. Probably, we can use Python scripting to do different thing depending on
the linker script used by the target being debugged.
