Hello r7warlord@gmail.com,
Unfortunately, here we are handling questions about the Model-Based Design Toolbox.
However, a simple search provided me the following links, which can be a starting point for you.
On this page, FRDM-KL25Z|Freedom Development Platform|Kinetis® MCU | NXP
under Software > Development Software there a link to the Arm Keil MDK, probably what you are interested about.
Hope this helps,
Marius
