Stripped down core

[kodakrome]

Is it possible to strip out most functionality from the boom core? I've been trying to get the smallest possible out of order RV core with little success. Example: trying to disable the floating point unit results in a not found error. Is there any special setting to reduce/remove functions/ISA extensions? Thanks for any help.

Unfortunately, you'll have to do some RTL hacking to strip stuff out like FP, virtual memory, etc.
