Normally I'd recommend P&E Microcomputer Systems (http://www.pemicro.com), whose products we normally use with our development tools. However, they don't look like they support DSPs, although you could check.
However, Domain Technologies (http://www.domaintec.com/) has offerings that work with Freescale DSPs. I have no experience with their products so I can't vouch for their reliability. If no one else offers a suggestion, I'd Google for Freescale+DSP+Flash+programmer. HTH.
