Thanks for the clarification. I have been focused too much on the concept
of a kernel image customized for a single device.

I can see how having to support multiple platforms with a single kernel
image makes things more difficult, especially when trying to optimize for
something. I will have to think about how to manage this when trying to
optimize memcpy-related functions.
