Function located to a fixed address

ARM MDK 3.4: module / function startadress.
I would like to have a flash programming function on a specified address (0xf000) from where the normal program can be updated. This would be a simplified approach for ISP. If something goes wrong, JTAG will solve this problem.
I could not find a linker control which would allow this. I already searched forum, with no success.

Functionality:
a) first installed program (0x0000..<0xf000) contains ISP function on 0xf000
b) updated program (0x0000..<0xf000) does not contain ISP function, only absolut call to it.

Thanks for any hints Werner

Thanks Marcus, your extensive explanations gave me a good starting point. Checking out doulos.com made me order the C und C++ fÃ¼r Embedded Systems book.
