The STD/USER jumper is just an inversion of an address bit. 

However, note that the EB40a flash isn't heterogenous. It has 0x2000 
and 0x10000 size sectors. 

I assume you are not deploying the EB40a board, so you probably want to leave 
the jumper in the position(SDT?) where 0x1000000-0x1010000 has 0x2000 long 
sectors.

arm-elf-gdb when connecting to the target with BDI JTAG debugger does not have 
a start address. It simply halts the CPU. After a reset, the BDI JTAG debugger 
messes around with the remap registers(I haven't needed to look to carefully at 
what it is doing).

The concept of a "start address" doesn't really apply in the same way as it 
exists for PC applications(Linux/Windows). The situation is much more analogous 
to using the gdb "attach" command for a PC application.
