[U-Boot-Users] Stand alone applications

I have written a stand alone application for an MPC855T for U-Boot, which runs fine. My problem is that the .bin file is around 128kB, when the actual application only takes up about 4kB. The file is then zero'd out from about 4k until the end of the file (around 128kB) where there is about a 256 Byte block of what looks like strings. How do I get this compressed down to a file that is only as large as it needs to be?
