The first question to ask is "Do I need to write a new BSP?" :)
Second: Can I augment/modify an existing BSP?

Whether you use or modify an existing BSP, or create a new one,
you have to have a cross compilation toolset. This is the primary
thing you do with the RSB.
First, use the RSB to build the cross toolset.
Next, I recommend building RTEMS for a BSP from your processor
architecture that runs on a simulator. This gives you something to
easily experiment with and ensure your installation is correct.
What is the HW platform you are looking at?
