placing function in given offset

[pavithvishnu]

My reqiurement is to place a piece of function in given offset.
for example,
I need to create a single project. with bootcode and application
bootcode func -> just need to jump to application offset
application -> hello world code.

bootcode func should in 8000 offset
application is my main code should be in c800 offset.

can consider following partition.
Bootcode - offset 8000 length-2kb
Storage 0 - offset 8800 length -8kb
Storage1 - offset A800 length - 8kb
Application - offset C800 length -256kb

can anyone help me out, how to achieve my requirements in a single project. Also i have memory constraints bootcode func should not exceed 2kb.
