Olimex makes an 
inexpensive adapter for the 10 Pin connectors on modern Cortex M4 devices.
This will work for your own deisgns if you use the 10 pin JTAG standard, but not for the Standard 19 pin header that Freescale uses.
Future Sells the 19 pin adapter from IAR/ Segger
Please add a comment if you know somewhere else that also sells them…

Segger makes a more expensive one, and a non connector one that can be attached directly to the board (http://www.segger.com/pricelist-j-link-related.html#Adapters) . Also the IAR iJet has both standard, btw https://www.iar.com/en/Products/Hardware-Debug-probes/I-jet/

Is a good reference for the 19 and 10 pin adapters themselves.
